Health conditions that trigger severe hair loss Polycystic ovary syndrome (PCOS) Polycystic ovary syndrome (PCOS) is a health condition that affects an estimated 5-10% of women of reproductive age. It is characterized by hormonal imbalances as well as the presence of cysts on the ovaries. While most people with PCOS are aware of the more common health issues such as infertility, body mass gain, and acne, many are unaware of its potential to trigger severe hair loss. In women with PCOS, increased testosterone levels promote excessive hair growth on the face and body while inhibiting the health of existing scalp hair. This hormonal imbalance places more strain on the hair follicles, making them unable to produce healthy new hair as quickly as usual. With time, this effect can make it difficult for these follicles to sustain hair health and trigger alopecia or severe hair loss.
