finasteride hirsutism placebo topical finasteride Propecia

TLDR Finasteride cream didn't significantly reduce hair more than a placebo, but users felt it helped.

The study investigated the efficacy of 0.5% finasteride cream in treating idiopathic hirsutism in 35 women by applying the cream to one side of the face and a placebo to the other. After 6 months, both the finasteride and placebo sides showed a significant reduction in hair number and thickness, but there was no statistically significant difference between the two treatments. Despite the lack of objective changes, most patients reported a perceived decrease in hair growth on the finasteride-treated side.
