PROPECIA works on a key cause of hair loss by significantly reducing the amount of DHT. Specifically, PROPECIA inhibits the formation of DHT in your scalp. Lowering DHT appears to inhibit the further shrinking of affected hair follicles. DHT is a substance in the body that can shrink the hair follicle until it no longer produces visible hair. Scientists believe DHT and family history are key factors in hair loss. PROPECIA helps regrow visible hair and reduces further hair loss.
It is, in fact, the first and only FDA-approved pill proven to treat male pattern hair loss on the vertex (top of head) and anterior mid-scalp area (middle front of head) in men.
