Minoxidil was the first FDA approved medication for treating hereditary hair loss. Originally used as an oral medication for treating hypertension, patients on minoxidil frequently complained of excessive hair growth on the scalp and face. Topical minoxidil was approved by the FDA in 1988 after studies showed it was effective for treating male pattern hair loss. Since that time both females and males suffering from inherited hair loss have used minoxidil with great success.
Presently, minoxidil is FDA-approved for men in a Rogaine® 5% solution and foam. The solution is applied with a dropper but can be messy and difficult to apply. Many prefer the less greasy foam formulation. Patients who are highly motivated can apply the product twice daily. It is preferred to use on a dry scalp (so the product is not diluted) but some men prefer to apply it to towel-dried hair after showering. The key is to find a routine that works for you and stick with it! Consistent use for a minimum of 6-12 months is necessary in order to see results.
Minoxidil for Women:
5% minoxidil foam is now FDA approved for once-daily treatment of hair loss in women. This occurred after one study published in the Journal of the American Academy of Dermatology showed that the 5% minoxidil formulation applied once daily is just as effective in women as the 2% applied twice daily. Women who don't wash their hair often may prefer to apply the 5% solution once daily with a dropper. That way they can wash and style their hair normally in the morning. It is not essential to wash the hair daily, but a slight residue may build up on the scalp after a few days’ use.
