Male pattern baldness occurs in men mostly due to a combination of genetic factors and the production of the male hormone dihydrotestosterone (DHT), which weakens hair follicles and results in hair loss. Men who are bald have more DHT levels in the balding part of the scalp than in other parts of the body.

Propecia works in the body by specifically lowering the levels of DHT in the scalp. This prevents further hair loss. Propecia can not work to affect hair in other parts of the body.
