Minoxidil, commercially known as Rogaine®, is an FDA-approved, over-the-counter topical medication for the treatment of hair loss in both men and women. It has been used since the late 1980s as a 2% solution, with a 5% solution now available as well that is considered significantly more effective.
Rogaine is applied directly to affected areas of the scalp to impede hair loss and stimulate the regrowth of hair. Although Rogaine is not considered a miracle treatment, it is often effective in 30% of patients, with slightly higher success rates for females. This treatment is most effective for patients with recent hair loss caused by androgenetic alopecia, as well as those suffering from relatively small areas of hair loss.
