Understanding Scalp Psoriasis: Causes, Symptoms, and Differences from Other Conditions

Psoriasis is a chronic autoimmune disease that affects an estimated 125 million people worldwide, with 45 to 56 percent of those individuals experiencing it on the scalp. It occurs when the body’s immune system mistakenly attacks healthy skin cells, leading to an overproduction of new cells that accumulate on the skin’s surface. This results in thick, red, and scaly patches that can be particularly problematic on the scalp.

Scalp psoriasis can be differentiated from other similar-looking conditions like seborrheic dermatitis. While both can cause a red, flaky, and itchy scalp, psoriasis often produces thicker, drier patches that can extend beyond the scalp, whereas seborrheic dermatitis is usually confined to the scalp and accompanied by more greasy, yellow-tinged dandruff flakes.

Top Dermatologist-Recommended Shampoos for Scalp Psoriasis

When it comes to managing scalp psoriasis, the right shampoo can make a significant difference. Dermatologists recommend looking for products containing specific ingredients that can help soothe the scalp and reduce symptoms.

Selsun Blue Moisturizing Dandruff Shampoo

This long-time favorite for dandruff sufferers may also be effective for mild cases of scalp psoriasis. It contains 1% selenium sulfide to combat dry, itchy flakes, as well as aloe to soothe and nourish the scalp.

Philip B Anti-Flake Relief Shampoo

Dermatologist Ava Shamban recommends this shampoo, which features zinc pyrithione (also known as zinc omadine) as the main active ingredient, along with soothing botanicals like sage, juniper, and tea tree oil. It’s a coal tar-free option for those who want to avoid that ingredient.

Head & Shoulders Clinical Strength Dry Scalp Rescue Shampoo

The selenium sulfide formula in this shampoo helps relieve stubborn dandruff symptoms while leaving hair feeling soft and clean. According to dermatologist Wilkerson, the inclusion of zinc pyrithione works synergistically with the selenium sulfide to address the root cause of dandruff and scalp irritation.

Philip B Peppermint Avocado Scalp Scrub

Exfoliating scalp scrubs can be beneficial for psoriasis, says Shamban. This one contains Australian sea salt, as well as hydrating ingredients like peppermint, avocado, and eucalyptus oils to cleanse, soothe, and rejuvenate the scalp.

Key Ingredients to Look for in Scalp Psoriasis Treatments

When selecting products for scalp psoriasis, Shamban recommends keeping an eye out for the following beneficial ingredients:

Salicylic Acid

Salicylic acid can help soften and break down the thick, scaly patches that often develop on the scalp with psoriasis. It also helps other medications and treatments penetrate deeper into the skin.

Zinc Pyrithione (Zinc Omadine)

This ingredient has both antimicrobial and anti-fungal properties, making it effective for addressing the underlying causes of scalp irritation and conditions like seborrheic dermatitis that can co-occur with psoriasis.

Tea Tree Oil

Tea tree oil is another beneficial ingredient for its antimicrobial and anti-inflammatory effects, which can help soothe the scalp and reduce symptoms.

Seeking Professional Treatment for Severe Scalp Psoriasis

While over-the-counter shampoos and treatments can be helpful for managing mild to moderate scalp psoriasis, more severe cases may require prescription medications or other professional interventions. It’s important to consult a dermatologist if your symptoms are persistent or worsening, as they can provide a proper diagnosis and recommend the most effective course of treatment.

Maintaining a Healthy Scalp and Hair with Scalp Psoriasis

In addition to using the right shampoo and other topical treatments, there are several lifestyle and hair care habits that can help support a healthy scalp and hair when dealing with psoriasis:

  • Gently exfoliate the scalp to remove built-up scales and flakes
  • Avoid harsh hair products and styles that may further irritate the scalp
  • Minimize stress, as it can exacerbate psoriasis symptoms
  • Stay hydrated and maintain a balanced, nutrient-rich diet
  • Protect the scalp from environmental aggressors like sun exposure

By understanding the nature of scalp psoriasis, utilizing the right products and treatments, and adopting healthy scalp and hair care habits, individuals living with this chronic condition can find relief and manage their symptoms effectively.

8 Best Shampoos for Psoriasis, Dermatologist-Approved 2021

Living with a dry, itchy, and flaky scalp can be challenging, but even more so if you have scalp psoriasis—which is why a good shampoo for psoriasis comes in handy. But we’ll get to that shortly. It’s estimated that 125 million people worldwide have psoriasis (celebs like Kim Kardashian, Cara Delevingne, and Jonathan Van Ness all have the chronic autoimmune disease), with 45 to 56 percent having it on the scalp. The good news is, there are products out there that can help decrease the symptoms of scalp psoriasis, such as specially formulated shampoos, so we turned to experts for advice.

It’s best to know what psoriasis is, since it can look similar to other scalp conditions (keep scrolling past the products for more info). If you suspect you have it, see a doctor to get properly diagnosed.

Recommended shampoos and products for scalp psoriasis

Selsun Blue Moisturizing Dandruff Shampoo — $7.00

A longtime favorite of dandruff sufferers, Shamban says Selsun Blue may also work well for more mild psoriasis cases. It contains 1 percent selenium sulfide to combat dry and itchy flakes, plus aloe to soothe and nourish the scalp.

Philip B Anti-Flake Relief Shampoo — $42.00

Shamban likes this shampoo as its main active is zinc pyrithione (also known as zinc omadine) and also includes sage, juniper, tea tree oil (which she recommends) and soothing aloe vera. Note: There is both an extra strength formula and this coal tar-free formula—coal tar is an effective treatment for scalp psoriasis, according to the AAD, but some people may want to avoid it, as there are potential side effects such as skin sensitivity.

Head & Shoulders Clinical Strength Dry Scalp Rescue Shampoo — $9.00

The selenium sulfide formula relieves stubborn dandruff symptoms while leaving hair feeling soft and clean. “Another ingredient to make sure is included in your scalp regimen, is ZPT [zinc pyrithione], as it works with selenium sulfide to address the source of dandruff and its symptoms, an irritant resulting from a natural occurring fungus on the scalp,” says Wilkerson.

Philip B Peppermint Avocado Scalp Scrub — $75.00

“Exfoliating scalp scrubs and calming, moisturizing ingredients are helpful,” says Shamban. This one contains Australian sea salt, plus hydrating peppermint, avocado, and eucalyptus oils to cleanse, soothe, and rejuvenate the scalp.

What is psoriasis?

According to Ava Shamban, a board-certified dermatologist based in Beverly Hills, psoriasis causes the body to create an overproduction of new skin cells over the course of a few days rather than weeks like normal skin does, resulting in the immune system mistakenly attacking our normal, healthy skin cells.

“As our dermis goes into high defense mode, it rapidly produces new cells that accumulate. The overdrive in skin cell production can accumulate anywhere on the skin’s surface, producing thick red dry patches of skin on face, body, palms of the hands, bottoms of the feet, and even scalp,” she explains. “There are several types of psoriasis, with the most common form being plaque psoriasis which presents as thick and scaly patches that are most often red, raw, painful, extremely dry, flaky, cracking and itchy. In extreme cases they can even bleed.”

What does scalp psoriasis look like?

Scalp psoriasis, Shamban explains, occurs on the scalp and nape of the neck, and thick patches can sometimes lead to hair loss. “Conditions are different in that our dermis is thicker naturally on the scalp and we have a significantly more active sebaceous network and millions of follicles unlike any other place on the body.” It’s also important to rule out other scalp conditions first. For example, Shamban says that psoriasis and seborrheic dermatitis share some similar presentations in the forms of red, scaly skin. “Seborrheic dermatitis is usually very itchy and often a yellow accompanied by dandruff flakes down the hair shaft,” she says. “Psoriasis however has a tendency to extend beyond the scalp while seborrheic dermatitis is usually confined to the scalp. In addition, the scales may be thicker lesions and somewhat drier in appearance than seborrheic dermatitis.”

Ingredients that can benefit scalp psoriasis

Shamban says that when looking for products, keep an eye out for gels and shampoos or pre-treatments containing salicylic acid, as it can help soften thick patches of skin on the scalp. Another good thing about salicylic acid? It penetrates into skin and pores, allowing other medications for other symptoms to get in deeper. “Look for products with antibacterial, antimicrobial, and anti-fungal properties that can help treat seborrheic dermatitis and scalp psoriasis,” she adds. “Antifungals also inhibit yeast growth, a main factor in dandruff which is a secondary outcome with the condition.”

Ingredients to avoid

There are also certain shampoo ingredients to avoid, such as sulfates and alcohol and other drying agents, according to Shamban. And if you didn’t guess already, fragrance-free formulas are best. Meanwhile, Dr. Rolanda Wilkerson, Principal Scientist and Senior Manager of Scientific Communications in Beauty Care at Procter & Gamble, says that chemical treatments can cause dryness on the scalp. “I would not say it has to be avoided, however, it is best to make sure you are following the proper protocol and recommended frequency for using them so that the health of the scalp is not negatively impacted,” she says. “Dry shampoos, although can be your best friend while trying to prolong styles, can cause build up and dryness with daily use and no washes in between.”

The 4 Best Shampoos For Psoriasis

Dealing with psoriasis can be difficult and stressful — but there are ways to manage this autoimmune condition on your own. For example, if you have psoriasis on your scalp, using the right shampoo can make a big difference. According to board-certified hair loss expert Dr. William Yates, with whom Elite Daily spoke for this article, the best shampoos for psoriasis contain salicylic acid or coal tar, so look for products that contain one of those ingredients. Salicylic acid can soften and break down thick patches of psoriasis, while coal tar is useful for people experiencing scalp irritation and itching. Shampoos containing apple cider vinegar can also help soothe inflammation on the scalp, says Dr. Yates, who even makes his own.

Dr. Yates also recommends steering clear of products that contain added fragrance and strong chemicals. He’s also “not opposed” to using soothing oils on the scalp that can help calm irritation. And since psoriasis can be triggered by stress, he advises his patients to strive for as healthy and stress-free of a lifestyle as possible.

Below are the best shampoos for scalp psoriasis, all available on Amazon. But if using an over-the-counter shampoo isn’t doing enough to alleviate the psoriasis on your scalp, speak with your dermatologist to discuss short-term topical steroids and other treatment options.

We only recommend products we love and that we think you will, too. We may receive a portion of sales from products purchased from this article, which was written by our Commerce team.

“One of my favorite OTC shampoos is T/Gel, which contains coal tar,” says Dr. Yates. This is a popular drugstore product among people with inflammatory scalp conditions, and it received the National Psoriasis Foundation (NPF) Seal of Recognition, meaning it’s intended to be nonirritating and safe for people with psoriasis. Coal tar helps alleviate itching and reduce buildup on the scalp, so it’s also helpful for treating things like dandruff.

Do be aware that coal tar can temporarily discolor lighter-colored hair, and it also poses the risk of staining skin or clothing. For best results, leave this shampoo in your hair for a few minutes before rinsing it out throughly.

A Shampoo With A Higher Concentration Of Coal Tar

03

A Shampoo With Salicylic Acid

This medicated shampoo from Dermarest (yes, it also has the NPF seal) contains the other known effective ingredient for treating scalp psoriasis: salicylic acid, which works by removing scalp buildup and can thereby help relieve redness and itching. It comes with a matching conditioner, too, both for under $15 on Amazon.

04

A Shampoo With Apple Cider Vinegar

If you prefer milder ingredients to the more heavy-duty options above (or want another shampoo to alternate with your coal tar/salicylic acid shampoo), try Aveeno’s Scalp Soothing Apple Cider Vinegar Blend Shampoo. In addition to the clarifying apple cider vinegar, it contains skin-soothing oats, and has a fresh, pleasant scent, unlike most medicated shampoos. That said, if your skin has a known sensitivity to fragrance, this may not be the best choice for you.

If your scalp is super dry, that can exacerbate itching and irritation, which is why Dr. Yates says it’s fine to use soothing oils to replenish moisture on your scalp. For example, apply this 100% pure coconut oil as a leave-in treatment. Not only will it restore moisture to your hair and scalp, which may be dry from your medicated shampoos, but it can also be used all over your body.

What is scalp psoriasis?

Psoriasis is a common skin condition, characterised by red scaly thickened patches (plaques). It often affects the scalp. Scalp psoriasis may occur in isolation or with any other form of psoriasis.

The back of the head is a common site for psoriasis, but multiple discrete areas of the scalp or the whole scalp may be affected. Scalp psoriasis is characterised by thick scale over well-defined, red thickened skin. The scale is often silvery white. Psoriasis may extend slightly beyond the hairline (facial psoriasis).

Scalp psoriasis, even though often adequately camouflaged by the hair, is often a source of social embarrassment due to flaking of the scale and severe ‘dandruff’. Scalp psoriasis may not cause any symptoms at all or may be extremely itchy. It tends to be a chronic problem, lasting many years, although it often fluctuates in severity and extent.

In very severe cases, there may be some temporary mild localised hair loss, but scalp psoriasis does not cause permanent balding.

Sebopsoriasis

Sebopsoriasis is an overlap between psoriasis and another common skin condition, seborrhoeic dermatitis. Sebopsoriasis tends to have less silvery scale than psoriasis and more yellowish, greasy scale.

Pityriasis amiantacea

Pityriasis amiantacea is characterised by thick, yellow-white scales densely coating the scalp skin and adhering to the hairs as they exit the scalp. The scales are arranged in an overlapping manner like tiles on a roof or flakes of asbestos, hence the name. The underlying scalp skin may appear normal, aside from the scale, or can be reddened or scaly. Pityriasis amiantacea is often present without any apparent underlying cause but may be associated with psoriasis, seborrhoeic dermatitis or lichen simplex (another form of dermatitis).

Psoriatic hair loss

Most patients with scalp psoriasis do not lose hair despite thick plaques. However, hair loss and localised bald patches (alopecia) can occur.

  • Psoriatic alopecia often affects psoriatic plaques (ie, red, scaly, thickened skin)
  • Scratching, combing, pulling off scale can contribute by pulling out clumps of hair
  • The hair usually completely regrows after some time
  • Scarring alopecia due to psoriasis is rare
  • Generalised hair shedding can occur (telogen effluvium)
  • Psoriasis may be associated with other autoimmune diseases including alopecia areata
  • Treatment might lead to hair loss, for example, due to the oral retinoid acitretin or biologics

Scalp psoriasis associated with hair loss

Scalp care

Scalp psoriasis requires slightly different regimes from psoriasis affecting the skin elsewhere. This is due to hair, which makes the application of many topical products difficult and protects the scalp from the effects of ultraviolet light. Unfortunately, many scalp treatments for scalp psoriasis are messy and smelly. Most treatments will need to be used regularly for several weeks before a benefit is seen.

Special medicated shampoos can be purchased from the chemist.

  • Coal tar shampoos are suitable for most patients with scalp psoriasis.
  • Ketoconazole, ciclopirox, zinc pyrithione and other antifungal shampoos are effective for dandruff and seborrhoeic dermatitis. They have a varying effect on sebopsoriasis and psoriasis.

The shampoos work best if rubbed into the scalp well, and left in for 5 or 10 minutes and then reapplied. They are safe for daily use but may irritate if applied more than twice weekly. If you dislike the smell of coal tar, try shampooing again with a favourite brand, and use a conditioner.

More severe cases require leave-on scalp applications.

  • Alcohol-based, foam, gel or lotion forms of topical steroid and calcipotriol can reduce redness and itch, but they don’t lift scale very well. Use topical steroids intermittently; overuse results in more extensive and severe psoriasis.
  • Salicylic acid and coal tar creams work much better but are messy. Coconut oil compound ointment is a combination of coal tar, salicylic acid and sulphur and seems particularly effective. Leave on for at least an hour and shampoo off later. Most people rub the cream into the plaques at night and wash it off in the morning.
  • Dithranol may be effective but is difficult to use and may be messy as it stains hair and fabrics.

Use the scalp preparation daily at first then as the condition improves, reduce the frequency. In many cases the scale soon builds up again, so the creams may have to be applied regularly to keep the scalp clear. Topical steroids are best used only 2-3 times weekly, long term to avoid complications.

Cutting hair short helps control scalp psoriasis, probably by making the treatments easier to apply, but is not appealing to everyone.

Phototherapy is effective for chronic plaque psoriasis but challenging to deliver to the scalp. Special targeted devices and UVB combs have been devised, and appear very helpful. In some cases, prolonged clearance has resulted from a course of treatment.

Intralesional corticosteroid injections and systemic therapy may be justified for patients with severe scalp psoriasis that has failed to respond to topical treatments and targeted phototherapy. These include acitretin, methotrexate, ciclosporin and biologic agents.

Salicylic Acid is the single most popular active ingredient in dandruff shampoos on the market today.    An astonishing 24% of the shampoos we’ve reviewed contains the ingredient (almost 1 in 4).  And the reasons for that are – its effective and it’s incredibly versatile.  It’s so effective that it’s listed on the World Health Organization’s List of Essential Medicines, is an FDA approved treatment for seb derm and psoriasis and salicylic acid shampoos are an incredibly popular option to treat dandruff caused by both seborrheic dermatitis and scalp psoriasis.

We love this ingredient when used at the right time for the right condition.  And, as you’d probably expect with so many variations, some of the shampoos are best in class, whereas others have been as bad as it gets.

After completing approximately 100+ hours of research, and speaking to four board-certified dermatologists,  we’re in a unique position to name the best salicylic acid shampoos on the market today.

What’s in this article:

The Winner

Dead Sea Spa Magik Mineral Shampoo

Dead Sea Spa Magik Mineral Shampoo is a worthy winner of our best salicylic acid shampoo.

The shampoo is a unique formulation containing a combination of zinc pyrithione and salicylic acid.

Zinc Pyrithione is a gentle, well tolerated, antifungal agent found in many dandruff shampoos.  It’s used primarily to treat mild cases of seborrheic dermatitis.

Salicylic Acid is on the other hand used in shampoos, creams, and ointments mainly for its keratolytic effects – the ingredient causes the epidermis to shed more easily, helping to remove dry and flaky skin [4]. You’ll often see salicylic acid referred to as an exfoliator – and its added to dandruff shampoos to help shift existing build up.

Salicylic Acid and Zinc Pyrithione compliment each other so well because Salicylic Acid can soften the existing build up on your scalp and help the Zinc Pyrithione penetrate the scalp more effectively [5].

Dr. Matthew Zirwas, a board-certified dermatologist and founder of Bexley Dermatology in Bexley, Ohio, prefers shampoos that contain multiple active ingredients.  He told us, “compounded shampoos that contain multiple active ingredients work much better than regular shampoos.”

Aside from the active ingredients, Dead Sea Spa has chosen some innovative help ingredients that really made this shampoo stand out.

The surfactants are extremely gentle.  And while Dead Sea Spa isn’t sulfate-free, the sulfate used is Sodium Coceth Sulfate. The good news is that Sodium Coceth Sulfate is an extremely gentle surfactant often see it used in baby cleansers, gels, and cleaners.

In addition to Sodium Coceth Sulfate, the shampoo contains Sodium Beeswax (aka beeswax soap). This ingredient is derived from beeswax and acts as both an emulsifier and a cleaning agent. The beauty of sodium beeswax is that it provides the same antiviral, anti-inflammatory, and antibacterial properties of beeswax while helping to moisturize and strengthen the skin defense barrier.

The shampoo also contains a number of extracts including:

  • Chamomile – often used as a natural treatment for itchy skin caused by dry skin or eczema
  • Linden flower – an antioxidant that locks moisture into the skin. It’s also an astringent, balancing your scalps natural sebum production. It can also calm an irritated an itchy scalp.
  • Rooibos – an antioxidant that helps fight free radicals in the skin. These same antioxidants help soothe irritations caused by sunburn, eczema, or dryness of the skin. Rooibos also contains AHAs and zinc. AHA’s are a great exfoliator that helps get rid of older layers of skin cells. Zinc is an antifungal agent.

It must also be noted that these extracts contain fragrances. Some of these fragrances may be too much for a sensitive scalp, so pay attention if you’re fragrance sensitive.

Washing with this shampoo is a pleasure.  The liquid is a lightly scented thick white liquid that foams well. Our reviewer said their hair felt great after the shampooing with lots of bounce and volume. It didn’t feel like a medicated shampoo at all, and more like a high-end salon shampoo.

Aside from the fragrances, our only gripe with this shampoo is the addition Cocamidopropyl Betaine, a secondary surfactant that has the dubious distinction of being awarded the contact allergen of the year by the American Contact Dermatitis Society in 2004.

While no shampoo is perfect for everyone, Dead Sea Spa have done an outstanding job in formulating a unique, highly intelligent shampoo

We simply can’t recommend this shampoo highly enough.

Dead Sea Spa Magik Mineral Shampoo
Dead Sea Spa Magik Mineral shampoo is a worthy winner of our best salicylic acid shampoo. It looks and washes like a premium product but doesn’t have a price tag to match. Dead Sea Spa has formulated a shampoo lacking many of the harsh chemicals you often find in dandruff shampoos. They have instead added extracts of chamomile, linden flower, rooibos and beeswax to create one of the most innovative dandruff shampoo formulations we’ve ever seen. Just steer clear if you’re sensitive to fragrances.

The Runner Up

Vichy Dercos Anti-Dandruff Sensitive Shampoo

Vichy is a cosmetics company of some repute in the world of female skin care and not in the world of shampoos. However, this sensitive skin dandruff shampoo is simply outstanding.
The shampoo is sulfate free, paraben free and colorant free but contains a combination of Piroctone Olamine and Salycic Acid to control dandruff. Piroctone Olamine is an anti-fungal ingredient which, in recent studies, has been shown to be more effective than the far more established Zinc Pyrithione when used in combination with Salicylic Acid.[9]

Instead of sulfates, Vichy has added a number of gentle cleaning agents which our reviewer said left their hair feeling, “absolutely fantastic”.

No doubt the addition of Bisabolol help with this. Bisabolol is an anti-inflammatory that helps to calm and soothe your skin. It can help the skin to absorb other active ingredients more effectively. It’s found in chamomile and has been used for centuries for its skin healing properties.

Joint 3rd Place

Neutrogena T/Sal Therapeutic Shampoo

In joint 3rd place comes two “pure” salicylic acid shampoos that we simply couldn’t separate.

Neutrogena T/Sal shampoo is a 3% salicylic acid formula that is a classic brand with a fervent following. The shampoo is free of sulfates, parabens and fragrances and as such is virtually odorless. T/Sal is a clear thick shampoo that washes extremely well. Our reviewer couldn’t believe that the formulation was so gentle without requiring any harsh sulfates. In their words, “it felt really luxurious. Certainly for a medicated shampoo.”

Neutrogena T/Sal Shampoo
Along with DHA Sal Shampoo, the best pure Salicylic Acid shampoo we’ve yet reviewed. The shampoo contains 3% Salicylic Acid combined with a fragrance-free, sulfate free and virtually every other nasty ingredient free formulation. It does this and still feels luxurious when washing.

Neutrogena should be exceptionally proud of this top class shampoo.

Which leads us to our other 3rd place salicylic acid shampoo

DHS Sal Dandruff Shampoo

This 3% salicylic acid shampoo contains few ingredients, is clear and does not contain any colorants or fragrances. It is not thick, but somewhat runny and resembles and acts much like a plain soap. The shampoo suds quite easily into a white, opaque foam and left our reviewers hair, “feeling fairly soft”, but they still recommend using a conditioner if you’re used to that level of softness.

The only ingredient to look out for is Sodium Laureth Sulfate, considered a gentler sulfate than SLS but worth pointing out all the same.

DHS Sal Shampoo
DHS Sal Shampoo is an outstanding 3% salicylic acid shampoo designed to treat Psoriasis and Seborrheic Dermatitis.

The shampoo contains relatively few ingredients, is gentle and won’t break the bank.

If you’re not sensitive to sulfates and are looking for a good salicylic acid shampoo, this is an excellent performer.

Yet again, DHS have produced a shampoo that we can’t recommend highly enough.

The 10 Best Salicylic Acid Shampoos

Vichy Dercos Anti-Dandruff Sensitive Shampoo

Designed to treat Seborrheic Dermatitis

One of the best and mildest shampoos out there for seb derm sufferers with sensitive skin.

Containing both Piroctone Olamine and Salicylic Acid as well as being SLS free, paraben free, artificial color free this shampoo has an absolutely outstanding choice of active and inactive ingredients.

There are still two or three chemicals in there that some may find irritating. Otherwise this would have been a five out of five performer.

DHS Sal Dandruff Shampoo

Designed to treat Seborrheic Dermatitis and Psoriasis

DHS Sal Shampoo is a 3% salicylic acid shampoo designed to treat Psoriasis and Seborrheic Dermatitis.

It’s an outstanding shampoo that washes well, contains relatively few ingredients, is gentle and won’t break the bank.

If you’re not sensitive to sulfates and are looking for a good salicylic acid shampoo, this is an excellent performer.

Yet again, DHS have produced a shampoo that we can’t recommend highly enough.

Capasal

Designed to treat Seborrheic Dermatitis and Psoriasis

Capasal have taken the unique step of combining 1% Coal Tar with 0.5% Salicylic Acid and added coconut oil.

It’s perhaps the most original and interesting shampoo formulation we’ve yet seen

While the shampoo is SLS, fragrance and paraben free there are still a few known contact allergens in there. Unfortunately it smells like a coal tar shampoo too.

That aside Capasal is an excellent shampoo for those who suffer mild to moderate scalp psoriasis.

La Roche-Posay Kerium Anti-Dandruff Shampoo

Designed to treat Seborrheic Dermatitis, Dry Scalp

La Roche Posay is a combination shampoo, combining both Piroctone Olamine and Salicylic Acid. The Salicylic Acid will help exfoliate existing dandruff build up while the Piroctone Olamine is designed to prevent any new outbreaks. It’s a match made in heaven.

I can’t let a mention of a review pass without commenting on how luxurious this shampoo feels and smells when washing – better than any medicated shampoo I have ever tried. And I’ve tried lots!

There are a couple of harsh ingredients but compared to the majority of the shampoos on the market, this is a first class Piroctone Olamine shampoo.

If you haven’t seen your favorite shampoo listed, chances are we have and it can be found if you check out all our salicylic acid reviews.

If there’s any we haven’t reviewed then please drop us a note and we’ll be absolutely delighted to look into it!

How we chose the winners

All our reviewers are experts in their field, be that product formulation, pharmacy or haircare.

They assess the primary purpose of the dandruff shampoo, by examining the active ingredients present in the formulation. These active ingredients are designed to control specific types of dandruff and we’ll explain what those are.

Our reviews will also assess the rest of the formulation, deconstructing the shampoos to their constituent parts and describe the key ones in detail.

In addition, we warn of the presence of any one of over 100 ingredients that can potentially itch, irritate and even cause dandruff themselves. A significant number (~90%) of these chemicals have never been tested for their effect on human health. Many of these chemicals are known to have adverse effects on our skin and one of these adverse effects is dandruff.

Unlike most review sites, our reviewers personally try every shampoo they review and they also assess how the shampoo washes, how it smells and look at the price point in their market. These may be medicated shampoos, but that doesn’t mean we want to compromise on a little bit of luxury!

What we won’t do is tell you if the shampoo will work for you. Our responses to the ingredients are highly personal, so we just couldn’t do that.

What we will do is explain, in layman’s terms, the purpose of the shampoo and what condition it is designed to alleviate.

What is Salicylic Acid?

A brief history

Salicylic acid is an intriguing ingredient, being a chemical precursor to ‘acetylsalicylic acid’ – more commonly known as aspirin. The watery bark sap of the willow tree (Salix alba) contains high concentrations of salicylic acid, which can be refined to make aspirin.

Salicylic Acid Crystals

For the past 120 years, aspirin has been used as a painkiller and anti-inflammatory, but now is more commonly used as an antiplatelet in the secondary prevention of cardiovascular disease [2].  The discovery of aspirin in the late 19th Century by the pharmaceutical company Bayer led to the creation of a new class of medications, the ‘non-steroidal anti-inflammatory drugs’ (NSAIDs). Research into the pharmacological mechanism of aspirin underpins our current understanding of inflammatory pathways, for which John Robert Vane, Sune Bergström, and Bengt Ingemar Samuelsson were awarded the 1982 Nobel Prize in Medicine [3].

What does Salicylic Acid do to the skin?

While salicylic acid is very closely related to aspirin, but they don’t have the same roles in the treatment of scalp conditions. Salicylic acid is used in shampoos, creams, and ointments mainly for keratolytic effects and local anti-inflammatory action. Keratolytic agents cause cells of the epidermis to shed more easily, helping to remove dry and flaky skin [4].  You’ll often see salicylic acid referred to as an exfoliator.

The keratolytic effects of salicylic acid are also used in certain products to increase the penetration of other ingredients. This can be necessary for dermatological conditions, where plaques and thickened skin prevent steroids from being absorbed into tissue – reducing efficacy [5].

And it’s this flexibility that makes it the single most widespread active ingredient on the market today.  It can be combined with virtually any other active ingredient to increase the efficacy of the other active ingredient.

How effective are Salicylic Acid shampoos at treating dandruff?

Salicylic Acid is commonly used to help combat dandruff caused by scalp psoriasis and seborrheic dermatitis.

The USFDA mandate that it can be considered a medicine is used in 1.8 to 3 percent concentrations in a shampoo.

It’s such an important healthcare treatment that:

Dr. Ben Barankin, a Toronto based board-certified dermatologist at the Toronto Dermatology Centre, recommends it’s usage when he told us, “For mild-moderate dandruff, my preferred over the counter dandruff ingredients include: zinc pyrithione, selenium sulfide, ketoconazole, tar and salicylic acid”.

How effective are Salicylic Acid shampoos at treating Seborrheic Dermatitis?

For a long time, seborrheic dermatitis was seen as a condition caused by excessive growth of skin cells (‘hyperproliferation), explaining the characteristic symptoms: flaky skin, itchiness, greasy skin. This rationalized the use of salicylic acid in shampoos. It’s now better understood that Malassezia yeasts play a role in the underlying condition, and so antifungal treatments are more useful first-line options (e.g. ketoconazole, selenium sulfide) [6].

Salicylic acid does not possess any antifungal properties necessary for the treatment of seb derm, but the keratolytic effects can help to remove flaky skin. The salicylic acid softens the existing build up while the anti-fungal can help prevent any further build up.

In addition, a recent study suggests that the presence of salicylic acid with an anti-fungal can help amplify the power of that anti-fungal agent. [7]

How effective are Salicylic Acid shampoos at treating Scalp Psoriasis?

Scalp Psoriasis is an auto-immune condition causing the hyperproliferation growth of skin cells. In a regular skin cycle skin, the turnover of skin cells takes about a month. If you have psoriasis, it can happen within a few days.

As a result, a number of raised plaques or patches of thick, scaly skin appear on various parts of your body.

The keratolytic properties of salicylic acid can help to soften and remove the flaky skin.

In severe cases of psoriasis, treatment is often combined with a topical steroid – the salicylic acid added to help penetration of the steroid – the scaly build up can prevent the steroid from entering the skin efficiently.

How often should I wash with a Salicylic Acid shampoo?

To use a dandruff shampoo, or any shampoo for that matter, shampoo, you should always follow the instructions on the label.

This isn’t always as straightforward as it sounds.  For example, Dead Sea Spa provides no guidance on frequency but instead recommend that you, “Apply to wet hair, massaging into scalp and hair. Rinse well. For best results follow with Spa Magik Hair Magic serum or Conditioning Scalp Mud.”

Neutrogena, on the other hand, recommends, “For best results, use at least twice a week or as directed by a doctor.”

So we asked a doctor for guidance.

Dr. Matthew Zirwas recommended trying a shampoo for, “at least a month because if your old shampoo had ingredients that were causing a dandruff-like rash of their own, it will take 4-8 weeks for that ingredient to work its way out of your body after you start the new stuff.”

For some further clarity, Dr. Ben Barankin, told us, “For mild-moderate dandruff, I recommend daily shampooing, and ideally alternating 3 shampoos, each with active anti-dandruff ingredients.”

And if it doesn’t work, board-certified dermatologist Adam J. Friedman, MD, FAAD, assistant professor of dermatology and director of dermatologic research, Albert Einstein College of Medicine explains via the AAD, “For most people, dandruff does not require medical attention. However, sometimes the flaking and itching that appears like dandruff is actually a medical condition, such as seborrheic dermatitis, psoriasis, fungal infections of the scalp, or eczema. If you continue to have symptoms after using a dandruff shampoo, consult a board-certified dermatologist.”

By visiting a board-certified dermatologist, you can be properly diagnosed and be prescribed stronger medication than you can pick up at the pharmacy. As Dr. Ben Barankin says, “for moderate to severe cases of dandruff, a steroid shampoo or leave-in lotion can be prescribed. A prescription ciclopirox olamine lotion is often a nice option.”

What are the risks of using a Salicylic Acid shampoo?

Salicylic acid shampoos are generally well-tolerated but should be avoided in those with a history of aspirin allergy. Only a very small amount of salicylic acid is absorbed into the bloodstream when applied to healthy skin. But this figure increases around 150 times when the skin is damaged (although this figure is for creams, and so will be lower for rinse-off shampoos). Toxicity has been reported, but these cases are typically associated with other contributory factors [8].

Systemic absorption is unlikely to result in any harm but reinforces that the lowest effective quantity should be used for the least amount of time. Typically in scalp conditions, this means using a medicated shampoo for two to four weeks, but exact recommendations vary by formulation and brand. Prolonged use of a keratolytic agent can also cause dry skin – worsening symptoms – and so excessive use should be avoided.

Scalp Psoriasis – an overview

Clinical Use of 1,25(OH)

2D3 and Its Analogs in Psoriasis and Other Skin Diseases

The use of 1,25(OH)2D3 and its analogs for the treatment of psoriasis resulted from two independent lines of investigation. Because psoriasis is a hyperproliferative skin disorder, it seemed reasonable that the antiproliferative effects of 1,25(OH)2D3 could be used for the treatment of this disease. Although it was known that 1,25(OH)2D3 was extremely potent in inhibiting keratinocytes proliferation before launching clinical trials in 1985, MacLaughlin and associates reported the observation that psoriatic fibroblasts were partially resistant to the antiproliferative effects of 1,25(OH)2D3[61]. This observation prompted MacLaughlin and associates to speculate, that 1,25(OH)2D3 may be effective in the treatment of the hyperproliferative skin disease psoriasis if pharmacologic doses were employed. The other line of investigation resulted from a clinical observation. In 1985, Morimoto and Kumahara reported that a patient, who was treated orally with 1α(OH)D3 for osteoporosis, had a dramatic remission of psoriatic skin lesions [62]. Morimoto et al. reported a follow-up study, demonstrating that almost 80% of 17 patients with psoriasis who were treated orally with 1α(OH)D3 at a dose of 1.0 μg/day for up to 6 month showed clinically significant improvement [63].

Currently, numerous studies have reported that various vitamin D analogs, including calcitriol (1,25(OH)2D3), calcipotriol, tacalcitol, hexafluoro-1,25(OH)2D3[64], and maxacalcitol are effective and safe in the topical treatment of psoriasis [65–73]. It has been shown that topical calcitriol and its analogs are very effective and safe for the long-term treatment of psoriasis [70–72]. Applied twice daily topically in amounts of up to 100 g of ointment (50 μg calcipotriol/g ointment) per week, calcipotriol was shown to be slightly more effective in the topical treatment of psoriasis than betamethasone 17-valerate ointment [72]. Efficacy of topical treatment with maxacalcitol was compared with topical calcipotriol treatment [68]. In this study, investigators’ overall assessment suggests that maxacalcitol 25 μg/g may be more effective than once-daily calcipotriol (50 μg/g). It has been reported that a mild dermatitis can be seen in about 10% of patients treated with calcipotriol (50 μg/g), particularly on the face [73]. This side effect (mild dermatitis on the face) is not reported after topical treatment with calcitriol. Allergic contact dermatitis to vitamin D analogs is very rare; however, cases with allergic contact dermatitis to other ingredients of the ointment including propylene glycol have been reported [74–76]. The most common adverse event observed in psoriasis patients treated with maxacalcitol (6–50 μg/g maxacalcitol ointment), was a burning sensation of the target plaque [68]. In three out of four patients developing this side effect in one study, symptoms were severe enough to require discontinuation of the treatment [68].

A double-blind, right/left comparison, placebo-controlled evaluation demonstrated efficacy and safety of topical treatment with hexafluoro-1,25(OH)2D3 (5 μg/g) in psoriasis patients [69]. Adverse events included mild irritation. This irritation did not necessitate discontinuation of the study medication. During the large area topical administration study period a cobblestone appearance was initially noted in a few patients. This resolved with continued therapy after 3–4 weeks. Hexafluoro-1,25(OH)2D3-treated plaques also developed very mild perilesional scales as observed with other vitamin D analogs [69]. Efficacy and safety of topical treatment with tacalcitol (4 μg/g and 20 μg/g) has been shown as well [69–71,77],. In one study tacalcitol treatment was generally well tolerated, and there were no serious or unexpected adverse events reported. However, discontinuation of treatment as a result of skin irritation was seen in 5.9% of these patients [71]. The greatest frequency of cutaneous side effects occurred during initial treatment, and the incidence decreased markedly as the treatment was well tolerated with continued use [71].

The results of four separate studies designed to evaluate specific local-safety parameters of various vitamin D analogs including cumulative irritancy, cutaneous contact sensitization, photoallergic contact sensitization, and phototoxicity were analyzed [78]. 1,25(OH)2D3 (3 μ/g ointment) was classified as nonirritant when compared with calcipotriol, tacalcitol, and white petrolatum (control). Petrolatum and tacalcitol were slightly irritant and calcipotriol moderately irritant. No sensitization was observed with 1,25(OH)2D3 (3 μ/g ointment). Regarding phototoxic potential, sites treated with calcitriol 3 μ/g ointment or vehicle ointment were less irritated than those treated with white petrolatum or those that were untreated. Using standard photoallergenicity testing methodology, there were no skin reactions of a photoallergic nature to the study material [78].

A long-term follow-up study demonstrated the efficacy and safety of oral calcitriol as a potential treatment of psoriasis [79]. Of the 85 patients included in that study that received oral calcitriol for 36 months, 88.0% had some improvement in their disease, whereas 26.5%, 26.3%, and 25.3% had complete, moderate, and slight improvement in their disease, respectively. Serum calcium concentrations and 24 h urinary calcium excretion increased by 3.9% and 148.2%, respectively, but were not outside the normal range. Bone mineral density of these patients remained unchanged. A very important consideration for the use of orally administered calcitriol is the dosing technique. To avoid its effects on enhancing dietary calcium absorption, it is very important to provide 1,25(OH)2D3 at night time. Perez et al. [79] showed that as a result of this dosing technique, doses of 2 μg/to 4 μg/night 1,25(OH)2D3 are well tolerated by psoriatic patients.

Patients with psoriasis may need intermittent treatment for their entire lives. Vitamin D analogs have been shown not to exhibit tachyphylaxis during treatment of psoriatic lesions, and topical treatment can be continued indefinitely.

Treatment of Scalp Psoriasis

A double-blind, randomized multicenter study demonstrated that calcipotriol solution is effective in the topical treatment of scalp psoriasis [80–82]. 49 patients were treated twice daily over a 4-week period [80]. 60% of patients on calcipotriol showed clearance or marked improvement versus 17% in the placebo group. No side effects were reported.

Treatment of Nail Psoriasis

The occurrence of nail psoriasis has been reported in up to 50% of patients. Nails, in general, are very difficult to treat and respond slowly. Until now, there has been no consistently effective treatment for psoriatic nails. It has been reported that calcipotriol ointment is effective in the treatment of nail psoriasis [83].

Treatment of Face and Flexures

Although the use of calcipotriol ointment is not recommended on face and flexures because of irritancy, most patients tolerate vitamin D analogs on these sites. It has been shown that calcitriol ointment (3 μg of 1,25(OH)2D3 per gram of petrolatum) was found to be better tolerated and would appear to be more effective than calcipotriol ointment (50 μg of calcipotriol per gram of petrolatum) in the treatment of psoriasis in sensitive areas [84].

Treatment of Skin Lesions in Children

During the past few years it has been shown that topical application of vitamin D analogs including calcitriol ointment (3 μg of 1,25(OH)2D3 per gram of petrolatum) is an effective, safe, and reliable therapy to cure psoriatic skin lesions in children [85–87].

Treatment of Psoriatic Lesions in HIV Patients

We have treated an HIV-positive patient suffering from psoriatic skin lesions with topical and oral 1,25(OH)2D3. The patient responded well, and there was no evidence of enhancement in HIV-disease activity or alterations in the number of T-lymphocytes, or CD4+, and CD8+ cells.

Combination of Vitamin D Analogs With Other Therapies

It has been reported that efficacy of topical treatment with vitamin D analogs in psoriasis can be increased by combination with other therapies, including methotrexate (MTX), very low dose oral cyclosporine (2 mg/kg/day), oral acitretin, topical dithranol, topical steroids, PUVA (psoralen plus UV-A) and UV-B, or narrow band UV-B phototherapy [88–96]. It has been shown that the combination of calcipotriol and MTX is safe and well tolerated [95]. The combination resulted in lower cumulative dosages of MTX compared with MTX and vehicle. Therefore the risk of MTX-induced side effects is substantially decreased [95]. Addition of calcipotriol ointment to oral application of acitretin (a vitamin A analog) was shown to produce a significantly better treatment response achieved with a lower cumulative dose of acitretin in patients with severe extensive psoriasis vulgaris, as compared with the group of patients treated with oral acitretin alone. The number of patients reporting adverse events was similar between the two treatment groups [90].

Complete clearing or 90% improvement in PASI was observed in 50% of patients treated with calcipotriol/cyclosporine versus 11.8% in the placebo/cyclosporine group. No difference was found in that study between the groups in short-time side effects. Kragballe and coworkers reported that efficacy of topical calcipotriol treatment in psoriasis can be improved by simultaneous UV-B phototherapy. Combination therapy of psoriasis with topical calcipotriol and narrow-band UV-B has been shown to be very effective for the treatment of psoriatic plaques [92]. One can speculate whether the therapeutic efficacy of UV-B in psoriasis may be at least in part because of increased cutaneous vitamin D synthesis. It has been shown that the combination of topical treatment with vitamin-D analogs and UV-radiation does not alter the tolerability or safety of therapy [97]. Vitamin D analogs may be topically applied at any time up to 2 hours before or immediately after UV-radiation [86]. Results of a controlled, right/left study have demonstrated that pretreatment of psoriasis with the vitamin D3 derivative tacalcitol increases the responsiveness to 311-nm UV-B [98]. Additionally, it was shown that tacalcitol ointment (4 μg/g) and 0.1% tazarotene gel are both comparably effective in improving the therapeutic result of PUVA therapy in patients with chronic plaque-type psoriasis [99]. The treatment requirements to induce complete or near complete clearing were significantly lower for both combination treatments than for PUVA monotherapy (P < .01). The median cumulative UV-A dose and number of exposures were 30.6 J/cm2 (95% CI 22.5–71.2) and 14 (95% CI 11–16) for tacalcitol plus PUVA, 32.3 J/cm2 (95% CI 22.5–73.8) and 14 (95% CI 11–19) for tazarotene plus PUVA, and 37.0 J/cm2 (95% CI 29.5–83.9) and 16 (95% CI 14–22) for PUVA monotherapy. No difference between the three regimens was observed with regard to duration of remission. Adverse reactions occurred more often with 0.1% tazarotene than with tacalcitol but were, in general, mild and completely reversible on using a lower concentration of 0.05% tazarotene. It has been concluded that besides accelerating the treatment response, both agents, by virtue of their UV-A dose-sparing effect, might also help to reduce possible long-term hazards of PUVA treatment. Previously, a case report described two patients treated with a combination treatment of calcipotriol and bath psoralens and UV-A who developed hyperpigmentation at the lesional sites where calcipotriol ointment was applied [100].

Combined topical treatment with calcipotriol ointment (50 μg/g) and betamethasone ointment was shown to be slightly more effective and caused less skin irritation than calcipotriol used twice daily [91]. A vehicle has been created with the objective of obtaining optimal stability of both calcipotriene and betamethasone dipropionate in the combination product. Early onset of action and efficacy of a fixed combination of calcipotriene and betamethasone dipropionate in this vehicle in the treatment of psoriasis has been reported, making it a standard therapy for the topical treatment of psoriasis [101].

Augustin et al. [102] evaluated scientific evidence about topical long-term therapy with 1,25(OH)2D3 analogs, corticosteroids, and their two-compound products in psoriasis vulgaris and scalp psoriasis and developed daily practice recommendations. Best evidence regarding topical long-term treatment was available for the two-compound formulation containing calcipotriene and betamethasone. In a comparative trial in psoriasis vulgaris the two-compound formulation showed superior tolerability and cost effectiveness compared with monotherapy. In scalp psoriasis the two-compound gel was superior compared with calcipotriene monotherapy. The authors concluded that because of a favorable risk–benefit ratio in maintenance trials and better cost-effectiveness, the application of two-compound products once or twice a week after initial therapy is recommended. It has been hypothesized that calcipotriol counteracts glucocorticoid-induced skin atrophy, which is associated with changes in the ECM. To elucidate the combined effects of calcipotriol and betamethasone on key ECM components, a comparative study to the respective monotreatments was carried out. The effect on collagen I synthesis, matrix metalloproteinase (MMP) secretion, and hyaluronic acid (HA) production was investigated in primary human fibroblast and keratinocyte cultures as well as in a human skin explant model. In that study, calcipotriol counteracted betamethasone-induced suppression of collagen I synthesis. Similarly, calcipotriol and betamethasone had opposing effects on MMP expression in both fibroblasts and keratinocytes. Moreover, calcipotriol was able to restore betamethasone-impaired HA synthesis in keratinocytes and prevented betamethasone-induced epidermal thinning in minipigs on treatment with a calcipotriol/betamethasone gel. In summary, these results showed for the first time in primary human skin cultures that calcipotriol reduces early signs of betamethasone-induced skin atrophy by modulation of key ECM components. These results indicate that the calcipotriol component of the fixed combination gel counteracts the atrophogenic effects of betamethasone on the skin [103].

Do Over-the-Counter Shampoos… | Southeast Dermatology Specialists

Living with scalp psoriasis can be difficult, especially if you’re not sure which treatment method is best. If you’re considering over-the-counter psoriasis shampoo treatments, here’s what you need to know.

Psoriasis Is Not Just Dry Skin

Unfortunately, many people believe that psoriasis is a cosmetic condition that can be treated with products designed to help heal dry skin. While products for dry skin may help ease some symptoms, psoriasis is an autoimmune condition that over-the-counter products designed for dry skin simply can’t effectively treat. In patients with psoriasis, inflammatory proteins cause an overproduction of skin cells. Without the necessary time to properly flake off, these skin cells build up and cause patches of excess skin buildup. As you can assume, an over-the-counter product for dry skin won’t have the desired effect on this condition.

You May Need to Rotate Treatments

While some people can find effective psoriasis treatment results with over-the-counter products, their success may be short-lived. In many cases, repeated exposure to a certain product or medication may reduce its effectiveness. This is especially true for any over-the-counter products, which can’t be sold with prescription-strength ingredients. Unfortunately, this may also make these treatments less than effective on your scalp. But if you do find an over-the-counter psoriasis shampoo that you like, be sure to keep a close eye on your condition’s progress. If you notice your scalp psoriasis getting worse or simply not improving, it may be time to switch up your treatment.

Check with Your Doctor First

Even if you’re investing in over-the-counter shampoos to treat your scalp psoriasis, it’s important to check in with your doctor about your purchase. Running the shampoo’s ingredients by them can help you better understand what they are. In addition, since they’re familiar with your condition and your skin, your doctor can alert you to how certain ingredients may affect both of those things.

Refrain from Washing Your Hair Vigorously

If you find an over-the-counter shampoo that works for you and helps with your psoriasis, it’s still extremely important to be gentle with your scalp. Your skin and hair follicles are already sensitive as a result of your condition, and irritating them further could cause hair breakage and even further irritation to your scalp.

Look for Products with Salicylic Acid

Salicylic acid has been known to help with scalp psoriasis treatment. If you’re looking for an over-the-counter shampoo treatment, try to make sure there’s salicylic acid present. That being said, be careful when using scalp psoriasis treatments with this ingredient. Salicylic acid does help the outer layers of skin shed, but it can also irritate the skin and weaken the hair, which could lead to breakage. As we noted above, make sure you speak to your doctor before beginning any over-the-counter psoriasis shampoo treatments.

It can feel like a constant uphill battle to find a treatment that really works for your scalp psoriasis. If you have questions about an over-the-counter shampoo or you’re looking for a prescription-grade treatment, make an appointment to speak with a member of our team at SE Dermatology Specialists today.

Salicylic Acid Shampoo – What Is It, Benefits, And How To Use It

In our battle with breakouts, there are a few OTC ingredients we reach out to immediately. Salicylic acid tops that list. This BHA (beta hydroxy acid) exfoliates the skin, has comedolytic properties, and is often used to manage acne vulgaris, freckles, photodamage, and melasma (1).

While it is a common ingredient in most acne-fighting products, you will also find salicylic acid in shampoos. Its exfoliating properties help manage dry and itchy scalp. Keep scrolling to learn what else salicylic acid shampoos can do for your hair and scalp.

Benefits Of A Salicylic Acid Shampoo

Salicylic acid (SA) is a keratolytic (exfoliating) and desmolytic agent. Meaning, it disrupts the connective tissues in the skin and promotes shedding (1). This property of salicylic acid makes it beneficial for multiple issues. Some of them include:

1. Dandruff Management

This itchy and flaky scalp condition is caused by the abundance of Malassezia, a type of fungus. Salicylic acid is often used for treating dandruff (2). It dissolves the flakes, making them easy to be washed off. This minimizes itching and irritation.

2. Seborrheic Dermatitis

Seborrheic dermatitis (known as dandruff when it occurs on the scalp) on the body is a condition marked by flaky, itchy skin and oily skin patches. Salicylic acid helps manage the condition by dissolving the skin patches and flakiness.

3. Scalp Psoriasis

Psoriasis is a chronic inflammatory condition affecting any body part, including the scalp. It is caused by excess cell turnover on the skin, causing itchy, scaly, and red patches. Salicyclic acid can manage the psoriatic plaques, minimizing itchiness (3).

If you have scalp psoriasis, using salicylic acid shampoos can help manage the flare-ups. However, salicylic acid does not treat psoriasis. You have to use medicated products and take prescription medicines to minimize it.

Scalp issues often affect the overall scalp health and may trigger hair loss. Now, the question is, does salicylic acid minimize hair loss? Find out in the next section.

Can Salicylic Acid Combat Hair Loss?

No. Salicylic acid does not treat hair loss. However, it can help manage and minimize a variety of issues affecting your scalp health. This may help minimize itchiness and your urge to scratch your scalp and reduce the chances of hair loss.

Let us move on to find out how to use a  salicylic acid shampoo for effective results.

How To Use Salicylic Acid Shampoo Effectively

  • Soak your hair wet with lukewarm or room temperature water.
  • Massage your hair and scalp with a salicylic acid shampoo. Adjust the quantity of shampoo as per the hair length.
  • Be gentle when massaging and scrubbing your scalp with the fingers. Avoid scratching, especially if you have any scalp condition. Rub along the hair length.
  • Rinse your hair and scalp thoroughly with room temperature water.
  • Apply conditioner only to the bottom two-thirds of the hair. Leave it on for a few minutes, and rinse.

Here are a few things to consider when using a salicylic acid-based shampoo. 

Things To Consider While Using Salicylic Acid Shampoos

  • Consult a doctor before using salicylic acid shampoos, especially if you are undergoing treatment for a scalp issue.
  • Check for any allergic reactions to avoid serious skin issues.
  • Avoid using a salicylic acid shampoo on broken, irritated, and compromised skin. Do not use it on any open cuts and wounds.
  • Overusing salicylic acid shampoos can further irritate the skin and cause dryness and itchiness. Consult the doctor regarding the frequency or follow the instructions on the shampoo bottle.
  • Do not use any other hair care product with salicylic acid and SA shampoos simultaneously. This can irritate the scalp.
  • Do not use it on children. Consult a doctor before using a salicylic acid shampoo on a child’s scalp.
  • Check the percentage of salicylic acid in the shampoo. Determine what concentration may work for your scalp condition (if any). Consult a doctor for the recommended concentration.
  • If you are pregnant or planning to get pregnant and breastfeeding, ask your doctor before using salicylic acid shampoos.

Although salicylic acid shampoos are safe to use, unregulated use may cause adverse reactions.

The Side Effects Of Using Salicylic Acid Shampoos

Salicylic acid shampoos may cause (1):

  • Contact sensitization (allergic reaction)
  • Dry skin
  • Stinging sensation
  • Erythema or inflammation
  • Salicylism (SA toxicity)
  • Peeling
  • Crusting
  • Skin irritation

Conclusion

Salicylic acid shampoos can keep your scalp and hair healthy, thus helping you manage multiple scalp conditions. However, they cannot treat any scalp issues and hair loss. If you are dealing with a scalp condition, consult with your doctor before using salicylic acid shampoo.
