The Effect of Topical Finasteride in the Treatment of Idiopathic Hirsutism

The study investigated the effects of topical finasteride on idiopathic hirsutism in 38 women aged 18-52 years. Participants were divided into four response groups based on subjective evaluations of hair growth rate, hair density, and hair color changes. The study found a significant reduction in hair removal frequency (P<0.001) after using 1% finasteride cream for 3 months, although there were no significant changes in hair color or thickness after 6 months of using 0.5% finasteride. Despite the lack of objective changes, most participants perceived a decrease in hair growth over time.
