Excessive hair growth (hirsutism)

Hirsutism is where women have thick, dark hair on their face, neck, chest, tummy, lower back, buttocks or thighs. See a GP if it's a problem for you. It might be caused by a medical condition that can be treated.

Causes of hirsutism

Hirsutism is linked to hormones called androgens. It can happen if the level of these hormones increases or if your body becomes more sensitive to them.

The GP will check what's causing the hair growth.

They're also not usually available on the NHS and can be expensive.
