How effective is Propecia?
Finasteride (Propecia and Proscar) is effective at treating mild to moderate male-pattern hair loss. In two 24-month studies of men, ages 18 to 41, approximately 80% of the men maintained their base hair count (versus 28% on placebo), and 66% had visible regrowth (versus 7% on placebo). Most of the men in the study reported an increase in the amount of hair, a decrease in their hair loss, and an improvement in their appearance.
