Finasteride Treatment of Hair Loss in Women

This document reviews the use of finasteride for treating hair loss in women. While some studies have shown positive results, larger controlled trials have not demonstrated significant improvement in hair loss. Finasteride may be considered as a second-line option for women who do not respond to or tolerate topical minoxidil, but other potential second-line options include spironolactone, flutamide, and topical estradiol. Few adverse reactions have been reported in women receiving finasteride, but decreased libido and breast swelling and tenderness are possible side effects. Prior to initiating any drug therapy for hair loss, other potential causes of hair loss should be excluded.
