Treatment of female pattern hair loss with the androgen receptor antagonist flutamide.

Female pattern hair loss is a common but difficult to manage condition. Commonly used treatments include oral antiandrogens such as spironolactone and topical minoxidil. The response to treatment is variable. We report a woman whose hair loss progressed while using spironolactone and topical minoxidil in combination, but reversed with flutamide, a potent androgen receptor antagonist.
