Propecia (a brand name for finasteride) is a prescription medicine used for the treatment of male-pattern baldness. Male-pattern baldness is a hereditary condition caused by an excess of hormones called androgens.

Over half the male population over their mid twenties experience hair loss in some form. Most men experience the hair loss on the vertex and the anterior mid-scalp area. Propecia can slow down the hair loss in these areas, prevent further hair loss or in some cases even wake up sleeping hair follicles and make the hair grow out again.

Popecia is the only prescription pill used to treat hair loss in men. Propecia taken once a day is proven to stop the hair loss process and increase hair growth. propecia is a small pill containing 1mg of the drug finasteride.

Propecia works by decreasing the production of these hormones. In studies, Propecia stopped hair loss and caused some hair to re-grow in up to 48 percent of men with hair loss at the top of the head or at the back and middle part of the scalp when treated for 12 months. At 24 months, 66 percent of men reported improvement.

Propecia inhibits the production of DHT which in most men will bring the level below the hair growth threshold. As long as the patient is taking Propecia the level will remain reduced and the hair loss will be reduced or stopped. In some cases some of the hairs will even grow back out.

When high levels of a naturally occurring hormone called DHT are present in the scalps of men genetically disposed to Male Pattern Hair Loss, the growth phase of hair is shortened. Eventually, the hairs become so small as to be practically invisible. This can result in the classic male bald hairline if it is not stopped.
