Finasteride Treatment of Female Pattern Hair Loss

The study evaluated the effectiveness of oral finasteride therapy associated with an oral contraceptive containing drospirenone and ethinyl estradiol in premenopausal women with female pattern hair loss. Thirty-seven women were treated with oral finasteride, 2.5 mg/d, while taking an oral contraceptive containing drospirenone and ethinyl estradiol. At 12-month follow-up, 62% of the patients demonstrated some improvement of their hair loss with the use of finasteride, 2.5 mg/d, while taking the oral contraceptive. No adverse reactions to the drug were reported. Further studies are necessary to understand which patterns of female pattern hair loss respond better to this treatment.
