Hair loss in men.
The most common form of balding is male pattern hair loss, representing close to 95% of all hair loss cases. Mild to moderate male pattern hair loss affects about half of men by age 50. This type of hair loss results in receding hairline and/or balding at the crown. It is due to heredity, from either the mother or father’s side of the family, and is dependent on hormones.

DHT and hair loss.
DHT is one of many male hormones in the body. DHT is developmentally important early in a man’s life; however, it appears to be a cause of hair loss, as men get older. DHT shrinks the hair follicle until it no longer produces visible hair.

Doctors believe that excess DHT is an apparent cause of hair loss.
The causes of hair loss are not well defined; however, researchers have found that men with male pattern hair loss have increased levels of DHT in the balding area of their scalps. Human hair normally follows a cycle of growth, falling out, and new growth. But increased levels of DHT are believed to contribute to the shortening of the growth phase, and a shortening of the time it takes for the hair to fall out. This results in thinning of the hair on the scalp.

PROPECIA blocks the formation of DHT.
Science has found a way to affect DHT with a prescription taken once a day in tablet form: PROPECIA. Finasteride (the active ingredient in PROPECIA) blocks the formation of DHT and, in this way, appears to interrupt a key factor in the development of inherited male pattern hair loss in men. PROPECIA has been proven to effectively lower DHT in the scalp.
