Minoxidil Topical: Uses, Side Effects, Interactions, Pictures, Warnings & Dosing


Minoxidil solution and foam are used to help hair growth in the treatment of male pattern baldness. It is not used for baldness at the front of the scalp or receding hairline in men. The foam and 2 percent minoxidil solution is also used to help hair growth in women with thinning hair.Minoxidil belongs to a class of drugs known as vasodilators. It is not known how minoxidil causes hair growth. This medication is not used for sudden/patchy hair loss, unexplained hair loss (for example, if you have no family history of hair loss), or hair loss after giving birth.Do not use this product if you are 18 years old or younger.

How to use Minoxidil Solution, Non-

Read and follow all directions on the product package before using this product. If you have any questions, ask your doctor or pharmacist.

Clean and dry the scalp area before applying the medication. You may apply this product to damp hair. To use the solution, fill the applicator with 1 milliliter of medication (to the 1 milliliter line), or use 20 drops. Part your hair in the area of thinning and apply the solution evenly to the affected area of the scalp. Gently rub in. Allow the solution to dry completely before using other styling products (such as gels, mousse) or before going to bed.

Minoxidil for hair, the benefits and harms of minoxidil

Androgenetic alopecia most often develops in the stronger sex and leads to male pattern hair loss. This is due to the peculiarities of the hormonal background, in which the endocrine system produces an excessive amount of the male sex hormone – dihydrotesterone, which negatively affects the quality of the hair, causing hair loss, thinning and growth retardation.

It is worth noting that Minoxidil is mainly suitable for men. For the fair sex, androgenic baldness is very rare, in exceptional cases. And as an option, you can use 2% Minoxedil. A big plus of the drug is the absence of smell.

Minoxidil FAQ:

Ingredients Minoxidil

Supplied as a spray or foam. Active ingredient concentration: 2–15%. The drug is suitable for any form of hair, even for the most complex hairstyles.

The most popular minoxidil brands on the market are Rogaine and Alerana.

Rogaine consists of minoxidil, purified water and a combination of citric and lactic acids. Other components include stearic alcohol and glycerol. Alerana, in addition to the usual minoxidil and purified water, contains ethyl alcohol and propylene glycol.


There are situations when there is an allergic reaction to one of the components of the drug. Then, for the treatment of hair loss, the doctor may prescribe other drugs with a similar effect. Active analogues of minoxidil are preparations based on nanoxidil (Spectral DNS), aminexil (Vichy Dercos) and stemoxidine (Vichy Dercos Neogens).

To enhance the effect, in addition to taking medications, the doctor may recommend taking vitamins and microelements, the composition of which is selected specifically for hair, and not for general action. Also a good recommendation is mesotherapy and PRP/Price

The cost of the drug directly depends on the percentage of minoxidil in its composition. The most popular solutions are those containing 2% and 15% minoxidil. Accordingly, the first option will cost $13–15, while a five percent solution will cost $18–50.

The drug belongs to the conditional category “cost above average”, and due to the active appreciation of the dollar against the Russian ruble in recent days, its purchase may feel even more expensive. However, the price of the drug is fully justified, since minoxidil is one of the most effective substances for the treatment of hair loss, regardless of whether it is caused by a genetic predisposition or is one of the post-covid syndromes.

Instructions for use

It is best not to use Minoxidil as soon as a problem of hair loss is discovered, but to consult a trichologist. And especially not to use every day. Alcohol-containing solution often leads to flaking of the scalp. The maximum safe frequency is every other day for the night!

The daily dose of the drug – 1 ml of solution – is equal to seven injections on the scalp. In general, it is determined by the attending physician, but these are standard values. If the drug is supplied in the form of a foam, then 1 ml of the solution is approximately equal to half the vial cap.

Use of the product is as follows:

  1. First, the scalp is cleaned.
  2. The preparation is then gently rubbed into the skin.
  3. Leave on for several hours, the main thing is not to wash it off.

Regular use of the drug is implied, short-term use will not give the desired effect.

  • pregnancy;
  • breast-feeding;
  • allergic to minoxidil and other components of the drug;
  • skin lesions of the head;
  • diseases of the cardiovascular system, liver, kidneys;
  • Minoxidil is likely to be incompatible with other hair loss medications, we strongly recommend that you consult your doctor about additional contraindications.
Side effects

Rare but should be known in advance:

  • dizziness;
  • burning eyes;
  • allergy in the form of itching and rash;
  • swelling of the tongue, lips and throat;
  • lowering blood pressure;
  • palpitations; dyspnea.
Why is Minoxidil dangerous?

The appearance of side effects is possible both on the part of the hair and the body as a whole. Minoxidil is a crystalline powder that is dissolved in alcohol, which is quite drying to the skin and can cause seborrhea, dryness, tightness, and flaking. Harm from the use of Minoxidil can also be manifested from the side of the cardiovascular system – such manifestations as dizziness, tachycardia and chest pain are possible. An allergic reaction is also possible.
