Hirsutism is excessive body hair on parts of the body where hair is normally absent or minimal. The word is from early 17th century: from Latin hirsutus meaning "hairy".[2] It usually refers to a male pattern of hair growth in a female that may be a sign of a more serious medical condition,[3] especially if it develops well after puberty.[4] Cultural stigma against hirsutism can cause much psychological distress and social difficulty.[5] Discrimination based on facial hirsutism often leads to the avoidance of social situations and to symptoms of anxiety and depression.[6]
Hirsutism is usually the result of an underlying endocrine imbalance, which may be adrenal, ovarian, or central.[7] It can be caused by increased levels of androgen hormones. The amount and location of the hair is measured by a Ferriman–Gallwey score. It is different from hypertrichosis, which is excessive hair growth anywhere on the body.[3]
Hirsutism affects between 5 and 15% of women across all ethnic backgrounds.[8] Depending on the definition and the underlying data, approximately 40% of women have some degree of facial hair.[9] About 10 to 15% of cases of hirsutism are idiopathic with no known cause.[10]
