Minoxidil is available in over-the-counter (OTC) medicines that help address general thinning of head hair. Minoxidil causes widening of the blood vessels, which can help regrow hair on the top of the scalp. It can be found in single-ingredient hair regrowth products for both men and women.
Minoxidil is approved by the U.S. Food and Drug Administration (FDA) to help hair regrowth and is safe and effective when used according to the Drug Facts label directions. Hair regrowth products containing minoxidil are available in different dosage strengths and labeled to meet the unique needs of men and women. Women should never use a minoxidil hair growth treatment that is only intended for use in men. Hair regrowth is different for each person, and not everyone responds to minoxidil.
