Doctors believe male pattern hair loss is due to heredity and is dependent on hormonal effects. Doctors refer to this type of balding as Androgenetic Alopecia. Mild to severe male pattern hair loss affects 80 percent of men. It has been found that men with male pattern hair loss have increased levels of dihydro-testosterone (DHT) in their balding scalps. Scientists believe these increased levels of DHT affect the growth cycle, contributing to the thinning of the hair on the scalp. Propecia works by blocking the formation of DHT.

PROPECIA Reduces Levels of DHT
PROPECIA works by blocking the enzyme 5 alpha reductase. This reduces the level of hormone, DHT, in the scalp and allows hairs to revert to a normal growth cycle. This results in no further hair loss and significantly new hair growth in men with Male Pattern Hair Loss.

Propecia became the first anti-baldness pill approved by the FDA in 1997.

The active ingredient is finasteride 1mg.
