Androgenetic Alopecia in the Female: Treatment with 2% Topical Minoxidil Solution

The study evaluated the effectiveness of a 2% topical minoxidil solution for treating female androgenetic alopecia in a 32-week, double-blind, placebo-controlled trial involving 308 women, with 256 completing the trial. Results showed that the minoxidil group experienced an average increase of 23 nonvellus hairs per cm², compared to 11 in the placebo group. Moderate hair growth was observed in 13% of the minoxidil group versus 6% in the placebo group, while minimal growth was reported by 50% and 33%, respectively. Overall, 60% of the minoxidil group reported new hair growth compared to 40% in the placebo group. The study concluded that topical minoxidil was significantly more effective than placebo, with no significant changes in vital signs or serious medical events reported.
