Propecia Uses

Propecia for Hair Loss

Propecia is licensed for the treatment of certain types of male pattern baldness in men, including hair loss at the very top of the head and hair loss near the front and center of the head (see Does Propecia Work?). Propecia has not been shown to be effective for hair loss near the temples. Even though male pattern baldness can be a cause of female hair loss (called female pattern baldness), Propecia has not been shown to be effective for women (see Propecia for Women).

How Propecia Works

Propecia works by blocking the enzyme Type II 5α-reductase. This enzyme is responsible for converting the male hormone testosterone into dihydrotestosterone (DHT). DHT is the hormone most related to male pattern baldness. By decreasing DHT levels, Propecia helps to stop hair loss related to male pattern baldness. Propecia is not a baldness cure, and hair loss typically returns within a year of stopping Propecia.

Propecia Use in Children

Propecia has not been adequately studied in children and is not approved for use in children. Because Propecia affects certain hormones, the benefits of Propecia for alopecia in children may not be worth the risks.

Off-Label Propecia Uses

On occasion, your healthcare provider may recommend Propecia for treating something other than the condition(s) discussed above. This is called an "off-label" use. At this time, there are a few off-label Propecia uses, such as:
  • Treatment of female pattern baldness
  • Treatment of hirsutism in women (excess body and facial hair).
