Androgen effects on Hair

Although some women with hirsutism have increased amounts of male hormone (eg. testosterone), most have normal levels.


The problem in these women is that their hair is more sensitive than normal to small amounts of circulating hormone.


The hair grows more quickly and thicker in response to hormone. The increased hair growth is usually first noted in late teenage years and tends to gradually get more severe as you get older.


Blood tests may be arranged to make sure that the hirsutism is not due to excessive male hormone levels.
