Propecia prevents the conversion of testosterone to dihydrotestosterone (DHT) in the body.
Propecia is used for the treatment of male pattern hair loss on the vertex and the anterior mid-scalp area. Male pattern hair loss is a common condition in which men experience thinning of the hair on the scalp. Often, this results in a receding hairline and/or balding on the top of the head.
Propecia is for use by men only and should not be used by women or children.
