The Link Between PCOS and Excess Facial Hair

Facial hair growth by itself does not indicate that you have polycystic ovary syndrome (PCOS), though hirsutism (unwanted or excess body hair) is one of the most distressing symptoms of PCOS. 

In some cases, the exact cause of facial hair in women is never known, although it often runs in families.

Symptoms of Hirsutism

Most women have fine, light-colored, and barely noticeable thin hairs (called vellus hairs) that grow above the lips, on the chin, chest, abdomen, or back—this is usually referred to as peach fuzz and is normally developed in childhood.

When women have coarse, visible, dark hairs growing in the place of the vellus hairs in these areas, the condition is called hirsutism. These coarse hairs are referred to as terminal or androgenic hairs, which normally develop during puberty.


If your body makes too many androgens or male hormones, like testosterone, you may experience unwanted hair growth, especially in the central part of your body (between your breasts, belly button, inner thighs). 

Some causes of excess androgen productions, and thus hirsutism, may include the following conditions: 

Hirsutism is tied to the use of certain medicines and supplements, including but not limited to:

When PCOS Is to Blame

Though there is no definitive test for PCOS, a diagnosis is usually made after your doctor conducts an extensive review of your medical history and confirms the presence of the following symptoms: 

  • Irregular or absent menstrual periods
  • Signs of hyperandrogenism—like facial hair, hair loss, and acne—without another medical cause
  • Trouble losing weight and/or diabetes

To distinguish PCOS from other conditions, your doctor will likely take a full medical history and perform a physical and pelvic examination to look for signs of PCOS (such as swollen ovaries or a swollen clitoris). Usually, they'll also order blood tests to measure the following hormone levels:

Other tests may also be ordered, such as:

  • A vaginal ultrasound to create real-time images of your reproductive organs
  • A pelvic laparoscopy (a surgical procedure) to check for growths on your ovaries using a small camera
  • A tissue biopsy, if growths on your ovaries are present

Once all of the prescribed tests are complete, the doctor will look at all of the results and clinical information to come to a medical diagnosis. 

If you think your PCOS may be the cause of your hirsutism, you should see your physician about your symptoms.

Treatment Options

Since hair grows in different phases, in long 6-month cycles, hirsutism is generally a long-term condition . There are multiple treatment methods for unwanted hair and some treatments are more effective than others. Some examples include:

  • Medication, such as birth control pills and anti-androgen drugs (spironolactone)
  • Electrolysis, which has risks including swelling, scarring, and redness of the skin
  • Laser hair reduction (this method works best on fair-skinned people with very dark hair)
  • Shaving
  • Chemicals, plucking, and waxing

For overweight or obese women, weight loss may help reduce excess hair growth.
