Hirsutism is a condition in women that results in excessive growth of dark or coarse hair in a male-like pattern — face, chest and back.
With hirsutism, extra hair growth often arises from excess male hormones (androgens), primarily testosterone. It can happen if the level of these hormones increases or if your body becomes more sensitive to them.
The most common cause is polycystic ovary syndrome (PCOS). This is a condition affecting the ovaries that can also cause symptoms such as acne and irregular periods.
Eflornithine (Vaniqa) is a prescription cream specifically for excessive facial hair in women. It's applied directly to the affected area of your face twice a day. It helps slow new hair growth but doesn't get rid of existing hair. It can be used with laser therapy to enhance the response.
