Polycystic ovary syndrome (PCOS)can cause various symptoms, including irregular periods, ovarian cysts, weight gain, acne, and excess hair growth (hirsutism). While PCOS itself does not directly cause hair fall, hormonal imbalances associated with PCOS can contribute to hair loss in some women. The most common type of hair loss associated with PCOS is called androgenic alopecia or male pattern hair loss. It occurs due to the increased production of male hormones such as testosterone.
