Polycystic Ovary Syndrome (PCOS) is a common health condition that affects many women of reproductive age. It happens when the ovaries produce higher-than-normal amounts of male hormones called androgens. PCOS can cause a range of symptoms, including irregular periods, weight gain, acne, and trouble getting pregnant. One side effect that often worries women is unwanted hair growth in places where men usually have hair, such as the face, chest, and even around the nipples or on the breasts. This can be distressing, but it is a common symptom of PCOS.
How Does PCOS Cause Breast Hair?![2 - 2025-06-13T164956.413]( "PCOS and breast hair")
Dr Saloni Patil, Consultant at Dr Patil’s IVF and Fertility Clinic, Mumbai, explains that PCOS leads to hormonal imbalances in the body. “Women with PCOS have higher levels of androgens, which are male hormones that can trigger hair growth in areas like the chin, upper lip, chest, and breasts,” she says. This type of hair growth is called hirsutism.
Dr Patil adds, “Hirsutism is not dangerous, but it can affect self-esteem and confidence. The hair that grows on the breasts due to PCOS is usually coarse and dark, unlike the fine hair that is normally present.” She also notes that not all women with PCOS will develop breast hair, but those who do often have other symptoms of high androgen levels, such as acne or scalp hair thinning.
The reason for this hair growth is simple: when there are more androgens in the body, hair follicles in certain areas become more active. This leads to thicker, darker hair in places where women usually have only soft, light hair.

What Research Says About PCOS and Hair Growth![3 - 2025-06-13T165004.358]( "breast hair pcos")
A study published in the journal Human Reproduction found that about 70% of women with PCOS experience hirsutism, including hair growth on the chest and breasts. The study highlights that the severity of hair growth can vary from woman to woman and depends on genetic factors and the level of androgen hormones in the body.
The researchers also point out that hirsutism can be managed with medication, lifestyle changes, and cosmetic treatments like waxing or laser hair removal. Managing PCOS with a healthy diet, regular exercise, and weight control can also help balance hormone levels and reduce unwanted hair growth.
