Proscar (Propecia; generic name Finasteride) by Merck is indicated for the treatment of male pattern hair loss (androgenetic alopecia) and is used to increase hair growth on the scalp and to prevent further hair loss. Proscar (Propecia; generic name Finasteride) from Merck is also used to treat benign prostatic hyperplasia (enlarged prostate).
Proscar (Propecia; generic name Finasteride) from Merck works by blocking or reducing levels of the hormone DHT in the body. When levels of DHT are high, the hair follicles on your head shrink until they can no longer grow. By taking Propecia on a daily basis you can stop hair loss and promote new hair growth in as little as 3 months. Propecia does not affect hair on other parts of the body. Men with mild to moderate, but not complete, hair loss can expect to benefit from the use of Propecia. 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. Taking Propecia is easy -take a pill once a day. You can take it whenever you like, with or without food, in the morning or before you go to bed. The important thing is to remember to take it.
