Most of the time, women have fine hair above their lips and on their chins, chests, abdomens, or backs. The growth of coarse dark hair in these areas (more typical of male-pattern hair growth) is called hirsutism.
Women normally produce low levels of male hormones (androgens). If your body makes too much of this hormone, you may have unwanted hair growth.
In most cases, the exact cause is never known. The condition often runs in families.

Most of the time, hirsutism does not cause health problems. But many women find it bothersome or embarrassing.
