Hirsutism: causes and treatment for women.

Hirsutism is defined as an androgen-dependent, male pattern of hair distribution in women. It affects between 5-15% of all women across all ethnic backgrounds (Azziz, 2003). The presence of unwanted female facial hair (and male hair patterns in other body areas) is the devastating consequence of hirsutism. It is also estimated that up to 40% of the general female population have some degree of unwanted facial hair (Hamzavi et al, 2007). The treatment of hirsutism is twofold; treating the underlying cause and reducing visible hair. This article will seek to define the causes of hirsutism, explore current treatment options for the removal of unwanted hair and discuss the psychosocial effects for the woman with hirsutism.
