Propecia is for male pattern hair loss treatment, so yes to your answer basically. Propecia can be a help in your case i.e. to treat male pattern 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 a thinning of the hair on the scalp.
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.
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.
Most important, PROPECIA helps grow natural hair, not just "peach fuzz," and is as convenient to take as a vitamin: one pill a day.
PROPECIA begins to block the formation of DHT almost immediately; however, because hair grows slowly, visible results from PROPECIA take some time. In clinical trials, most men began to see the first benefit of PROPECIA — slowing hair loss — as early as 3 months. After 6 months, men may begin to experience regrowth. If PROPECIA does not work within 12 months, further treatment is unlikely to be of benefit.
