What Is Hirsutism?

Hirsutism is excessive growth of thick, dark hair in women in places where men typically grow hair, such as the face, chest, back or tummy. It is usually linked to higher levels of, or higher sensitivity to, androgen hormones.

What causes hirsutism?

Hirsutism most often comes from hormonal changes. The most common cause is PCOS, a condition that can also cause acne and irregular periods. Less often, hirsutism is linked to certain medicines, such as some steroids, or to rare hormonal conditions and tumors. Sometimes no clear cause is found.

Is all extra body hair hirsutism?

Fine, light hair on the face or body is usually not hirsutism. Many women notice more of this type of hair as they get older, especially after menopause. Family background also plays a role in how much body hair is normal for a person.

How is hirsutism treated?

A GP will look for the cause, often with a blood test to check hormone levels. Depending on the cause, options a doctor may discuss include weight management where relevant, the contraceptive pill, prescription creams that slow facial hair growth, and hair removal methods such as shaving, waxing or laser treatment. Treatment usually takes months to show an effect.

When is hirsutism urgent?

Sudden new hair growth together with a deepening voice or increasing muscle size needs an urgent GP appointment, as it can point to a rarer hormonal problem. Hirsutism can also affect confidence and mood, and that is worth mentioning to a doctor too.
