Is biotin effective: Does Biotin Really Work for Hair Growth? – Cleveland Clinic

Does Biotin Really Work for Hair Growth? – Cleveland Clinic

If you find yourself browsing the hair care aisle or searching the internet for hair treatments, one thing that might pop up is biotin. This B vitamin has a reputation for helping your locks stay healthy, and it’s frequently recommended by dermatologists to help with hair loss.

But can biotin actually help your hair grow, too? 

“We find biotin to be very helpful for hair disorders,” says dermatologist Wilma Bergfeld, MD. “It also makes nails thicker, and oral biotin is exceedingly safe.”

Does this mean it can also help your hair longer? Not quite. Biotin contains essential proteins that help with the development of your skin, nails and hair, but this doesn’t mean it’s a miracle product for your locks. Let’s brush up on what biotin can — and can’t — do for your hair.

Why does hair fall out?

If you’re dealing with hair loss, you’re likely wondering not only what you can do about it, but also why it’s happening in the first place. Hair loss has multiple causes, many of which are systemic. “If your hair is falling out at the roots, often something is going wrong in your body or in your life situation,” Dr. Bergfeld says.

Certain medical conditions are linked to hair loss. Among them are endocrine disorders, which include problems with your pituitary, parathyroid or adrenal glands, or your ovaries or testes. “For example, premenopausal women who bleed excessively may be losing iron, and anemia causes hair loss,” Dr. Bergfeld explains.

Anything that disrupts your gastrointestinal (GI) tract can also affect hair growth, she adds.

But one of the most common causes may surprise you: nutrition. “When we look at what our patients eat, we find they are often low in protein and essential vitamins,” Dr. Bergfeld notes. “Also, you need some carbohydrates to make hormones, and your brain needs fat.”

It’s important to understand what’s causing your hair loss, but this can take some detective work. Dr. Bergfeld says dermatologists start with a thorough physical exam. They consider not just your diet, but your exercise habits and family history as well. Then, they review your medications (because some can cause hair loss) and bloodwork.

Does biotin help increase hair growth?

Biotin is an essential vitamin that helps with the production of keratin (a protein that’s in charge of forming nails, skin and hair). Some research, including a 2016 study, has shown that a lack of biotin in your system can lead to hair loss.

In which case, you may be wondering if increasing your intake of biotin will lead to better hair growth. And any googling you may have done on the topic has likely brought up such claims. But first, it’s first important to know that there’s a difference between something that helps promote hair growth and something that helps prevent hair loss.

For now, there isn’t enough research to definitively state that biotin can help grow hair.

But biotin has been shown to help with preventing balding and hair loss.

In fact, biotin is primarily used for alopecia — a condition that causes hair loss in all sexes. “Biotin helps maintain hair growth and helps with inflammation,” Dr. Bergfeld says. “The hair follicle, the skin and the nails all benefit.”

In a small 2012 study, women with self-perceived thinning hair experienced improvement in their hair’s overall thickness and growth after taking a multivitamin that contained biotin. But as the multivitamin contained other ingredients, it’s hard to attribute it completely to biotin. 

Without robust research, is biotin something you should try? The good news is that taking biotin in reasonable amounts won’t do any harm.

How much biotin should you take?

If you want to make sure you’re getting enough biotin, the daily recommended biotin intake is 30 micrograms (mcg) for adults, according to the National Institute of Health. If you’re pregnant, you need about 35 mcg a day.

If you’re experiencing alopecia, your doctor may recommend certain biotin supplements or a higher biotin-rich diet as a way to combat hair loss. They may recommend upping your dosage to 3 milligrams (or 3,000 mcg) a day.

What types of biotin are there?

There are a couple different ways to reap the benefits of biotin. Believe it or not, you may be already getting a decent dose without knowing it.

Here are some ways you can get biotin:

Biotin-rich foods

First, you may consider working some biotin-rich foods into your diet. This is the best way to get biotin into your system naturally. And you may already have some items in your pantry or fridge that fit the bill.

Biotin is present in many foods, including: 

  • Beef liver (30.8 mcg).
  • Eggs (10 mcg). 
  • Salmon (5 mcg).
  • Pork chop (3.8 mcg).
  • Sweet potatoes (2.4 mcg).
  • Almonds (1.5 mcg).
  • Broccoli (0.4 mcg). 

Mega-B vitamins

If you have certain dietary restrictions or need an extra biotin boost, certain supplements may be used as alternatives.   

For supplementation, many dermatologists favor a mega-B vitamin combination that includes:

  • 3 milligrams (mg) of biotin.
  • 30 mg of zinc.
  • 200 mg of vitamin C.
  • < 1 mg of folic acid.

“Occasionally, the mega B-vitamin combination gives some patients minor gastric trouble, but switching them to biotin alone relieves it,” Dr. Bergfeld notes.

And if you can’t find the mega B-vitamin combination, you can buy biotin, zinc and vitamin C separately.

Biotin shampoo

If your goal is for biotin to help your hair grow, you may consider adding a biotin shampoo into your wash routine. Sounds like an easy fix, right?

It’s true that many shampoo brands utilize biotin in their formulas as a way to combat hair loss. However, similar to the research around biotin supplements, the data to support hair growth from biotin-infused shampoo is limited. But there’s no harm really in giving this kind of shampoo a try if you want your hair to feel fuller — but don’t expect a magical regrowth of hair.

Possible side effects of biotin

Working more biotin into your system (whether through supplements or diet) is generally safe. But it’s important not to overdo it. In some rare cases, too much biotin from supplements can cause stomach issues, trouble sleeping and skin rashes. 

Another concern surrounding biotin is that it may interfere with certain common lab tests done by your doctors. Best way to avoid this? Don’t take too much. Stick to the recommended amount and be sure to talk to your doctor before upping your dosage. And if you’re taking large amounts of biotin, be sure your healthcare provider knows before you do any lab tests. 

While there’s still a lot of research needed on the effects of biotin on hair growth, as well as preventing hair loss, it has been shown to work for some. But it’s best to first make sure you’re eating a well-balanced diet of biotin-rich foods before considering too many supplements.

What the Experts Have to Say – Cleveland Clinic

Biotin is a B vitamin that’s important for many body functions, including metabolizing food — the process of turning food into energy. And many people swear that biotin has improved their hair, skin and nail health, too.

But is biotin the magic solution to getting flowing locks, strong nails and glowing skin? Registered dietitian Courtney Barth, RD, explains the possible benefits of biotin and whether this nutrient could help you.

Benefits of biotin

Biotin plays an important role in converting carbohydrates, fats and proteins into energy. It also helps your body’s cells function well. Biotin is essential, which means you can’t live without it.

But why does biotin get superhero status when it comes to hair, skin and nail health? Maybe because biotin deficiency — not having enough biotin — can lead to:

  • Brittle nails.
  • Hair loss.
  • Red, scaly rash.

“But biotin deficiency is rare in the U.S.,” Barth explains. “So if you have thinning hair or brittle nails, it’s probably not due to a biotin deficiency. There’s usually another health condition causing these problems, such as iron deficiency or a thyroid issue.

So don’t assume taking biotin supplements will cure hair, skin or nail problems. “If you notice sudden changes in your hair, skin or nails, see your provider,” says Barth. “Don’t self-treat with biotin supplements without knowing the cause.”

How much biotin do you need?

Adults need 30 micrograms of biotin each day to avoid a deficiency. Most people get adequate biotin through their diet.

“Biotin is in many of the foods we eat, such as fortified cereal, egg yolks, meat and legumes (like lentils, chickpeas and beans),” explains Barth. “And it’s always better to get your vitamins and minerals through a balanced diet rather than supplements.”

If you’re pregnant or breastfeeding, you need more biotin, though — 35 micrograms per day.

“Pregnant or breastfeeding women often benefit from a prenatal vitamin,” says Barth. “Prenatal vitamins contain biotin, folic acid and other nutrients that are important for the health of the mother and baby. If you’re not sure which prenatal vitamin to take, ask your provider.”

Do biotin supplements help with hair growth?

Maybe you’re not worried about biotin deficiency but wonder whether a biotin supplement could help you get amazing hair. After all, many products advertise biotin as a hair growth booster.

“No studies have proven that biotin supplements will change the appearance of your hair, skin or nails,” Barth says. “But some people find that taking a biotin supplement helps them boost hair and nail growth. It’s usually not harmful to try biotin for thicker hair or healthier nails.”

If you decide to take a supplement, be patient. “It takes several months to see new hair or nail growth,” notes Barth. “Biotin may be worth a try if your doctor gives you the go-ahead. But it’s not a guarantee that you’ll see a major change in your appearance.”

Biotin supplement side effects

Biotin supplements have few side effects if you take them as directed. “Biotin supplements and B-complex vitamins are safe for most people, though they may cause a slightly upset stomach,” Barth says.

High-dose biotin supplements can also interfere with certain medical test results, so tell your healthcare provider if you’re taking them, advises Barth.

Biotin and other B vitamins are water-soluble, so it’s hard to overdose on them. “If you take in more biotin than you need, your body doesn’t store it,” Barth explains. “You naturally get rid of excess biotin and other B vitamins when you urinate.”

Still, more is not always better. Don’t take more than the dosage listed on the package and stop taking biotin if you notice side effects.

A healthy lifestyle builds natural beauty

You can enhance your hair, skin and nail health even without a supplement. A balanced diet with a variety of fruits, vegetables and protein is important for all three. Drink plenty of water, too.

“Healthy food and proper hydration will help you feel and look your best,” says Barth.

BIOTIN FOR HAIR LOSS: Is it effective?

When faced with unusual hair loss, it is important to know how to proceed in order to avoid significant loss of hair density. One of the most popular remedies in recent times is what is known as biotin, which can be found in some shampoos as well as in nutritional supplements. But, Is biotin really effective against hair loss?

En Hospital Capilar, hairdresser in Madrid, Murcia and Pontevedra, we tell you everything you need to know about biotin for hair.

What is biotin?

Before you know how biotin works on hair loss, it’s important to know what it really is. Biotin is nothing but a B vitamin that promotes the production of enzymes in hair and skin.

Biotin can be found in foods such as oily fish or eggs. Also found in some dried fruits such as walnuts. The ideal way to keep your hair in good condition is to avoid deficiency of this nutrient, including through a healthy and varied diet.

How does biotin affect hair?

The main function of biotin in hair is to facilitate the supply of nutrients to the hair follicles, promoting blood circulation and oxygenation of the scalp . This keeps the hair healthy and in the best condition.

In short, biotin, along with other types of essential hair nutrients, is essential for maintaining healthy hair.

Is it true that biotin slows down hair loss?

Recently, many people decide to take biotin supplements for hair loss. But is it true that consuming this nutrient alone can reverse the effects of hair loss?

As we mentioned earlier, biotin contributes to the proper functioning of the scalp. However, the consumption of biotin for hair loss or its topical application will not stop us from hair loss. Yes, it’s true that it can help, but should never be used as a single and isolated treatment for unusual hair loss .

Therefore, it cannot be said that biotin is effective in treating hair loss on its own, but it is beneficial for the hair.

How to deal with unusual hair loss

If we notice a significant loss of hair density and even the appearance of areas without hair on the head, it is important to know how to act in order to reverse the effects as soon as possible.

Use effective hair products.

In cases where hair loss is not accompanied by the appearance of bald spots, hair loss remedies are very useful. Also in people with more severe hair loss, they are an ideal addition to other medical treatments.

Go for Hair Treatments

Continuous advances in hair medicine mean we now have effective treatments for common hair problems such as hair loss or hair miniaturization.

En Hospital Capilar we have medically tested hair care products to take care of your hair and stop it from falling out. All of them require a preliminary capillary diagnosis to determine which one best suits the needs of each patient.

Hair Redensification Treatment

El Hair Redensification Treatment, or HRT, consists of pharmaco-mesotherapy tailored to each patient. Thus, drugs and vitamins are injected into the scalp through subcutaneous infiltrates to treat hair loss from their root.

Capillary Regeneration Treatment

Another hair treatment at Hospital Capilar is called Capillary Regeneration Treatment or CRT. By extracting a small amount of blood from the patient himself, rich growth factors are obtained, which are injected into the scalp. Thus, hair regeneration is stimulated and hair miniaturization is prevented.

Biotin supplement for what

Recently, more and more people pay attention to their health and begin to take care of proper nutrition and sufficient intake of vitamins and minerals. And one of the most important vitamins necessary for the normal functioning of the human body is biotin.

Biotin, also known as vitamin H or vitamin B7, is an essential nutrient that helps improve the body’s metabolic processes. Biotin is essential for the proper functioning of many systems and organs, including the skin, hair, nails, nervous system, and digestive system.

This is why biotin has become so popular as a food supplement, or dietary supplement (dietary supplement), which can be very beneficial for our health and overall well-being. In this article, we will look at the benefits of biotin in dietary supplements and the benefits of using this supplement in food.

General Health Benefits of Biotin

Biotin for beauty hair and nails

Biotin, also known as vitamin H, is considered an essential element for strengthening and growing hair and nails. It helps improve cell metabolism, which promotes the synthesis of keratin, an essential component of hair and nails.

Biotin is also considered a beauty and skin health vitamin. Scientists have proven that it helps maintain a healthy and radiant appearance of the skin, because it is involved in the synthesis of fatty acids important for skin health. Some additional benefits of biotin for skin beauty include increased elasticity and slowing down the aging process.

If you are looking to improve your nails and hair, adding biotin to your diet or taking biotin supplements may be helpful. You can find biotin in foods like eggs, spinach, and mushrooms, as well as supplemental form in dietary supplements.

The effect of biotin on the digestive system

Biotin is an important nutrient that affects the human digestive system. It is a necessary enzyme for many metabolic processes, including the metabolism of carbohydrates, fats, and proteins. Biotin also helps to synthesize hormones needed for the proper functioning of the digestive system.

Biotin can help speed up the process of breaking down food and increase the amount of digestive enzymes in the body. This in turn can improve nutrient absorption and prevent stomach and intestinal upsets.

In addition, biotin may be beneficial for people suffering from irritable bowel syndrome and other dental disorders. It can help reduce inflammation and improve metabolism in the body.

Like many men my age, I gradually began to lose a lot of hair. Despite the fact that I try to go to bed on time, eat right and monitor my health, baldness continued to progress. In search of a solution to this problem, I began to look for information about various supplements that will help restore hair health. Advised to try bad biotin.

To be honest, I was a little skeptical, as I had never taken such drugs before. However, I decided to experiment and bought myself a bad biotin. I have been taking it for several weeks now and notice that my hair has become thicker, shiny and strong. I continue to take it and hope that this drug will help me regain a beautiful and healthy head of hair.

Alexey Petrov

I have always had strong and healthy hair, but after I began to get involved in sports and an active lifestyle, the problems began. Frequent training, overwork, and poor nutrition began to have a negative impact on my health. The hair began to fall out, and the remaining ones became dull and weak. I went to a dermatologist for help and he advised me to start taking biotin supplements.

I was pleasantly surprised that dietary supplement biotin is a fairly affordable and inexpensive drug. I bought myself a course for 3 months and started taking it every day, following the instructions. After a week, I noticed that the hair stopped falling out so quickly and became stronger. Now, after about two months of using bad biotin, the hair has become much thicker and stronger, and also acquired a healthy shine. Moreover, I noticed that not only the hair, but also the nails became stronger and did not break.

I recommend this preparation to anyone who has experienced hair loss or wants to strengthen their skin, hair and nails.
