Propecia, also called by its non-brand name Finasteride, is a "DHT inhibitor" pill that is FDA approved to inhibit production of DHT through the entire body (called systemic). It does this through inhibiting the conversion of testosterone to DHT. Finasteride is taken orally and has a reported 29-68% success rate (vs 17-45% in patients receiving a placebo). It is effective only for as long as it is taken; the hair gained or maintained is lost within 6-12 months of ceasing therapy (Rossi, 2004). In clinical studies, Propecia, like Minoxodil, was shown to work on both the crown area and the hairline,[4] but is most successful in the crown area. For those in the early stages of hair loss, it is generally recommended to start slow, using propecia alone for at least a year, as it has very good maintenance rates, then adding other products, such as minoxidil, if regrowth is desired.

Propecia is the same as the oral prescription drug, Proscar, used in higher doses to treat an enlarged prostate. Some users save money by buying Proscar instead of Propecia , and split the pills in quarters using a pill-splitter to ensure the same amount as is present in Propecia is taken.

Propecia has been shown to be ineffective for treating hair loss in women, and shouldn't even be touched by pregnant or potentially pregnant women, as it causes severe birth defects in male fetuses.
