Hair loss in women with PCOS is primarily driven by hormonal imbalances, especially elevated androgen levels. These excess male hormones shrink hair follicles on the scalp, disrupting the natural hair growth cycle and leading to thinning, shedding, and a pattern of loss often concentrated at the crown and hairline (female pattern hair loss).

Because PCOS-related hair loss overlaps with other conditions like thyroid disorders, iron deficiency, and stress-induced shedding, identifying the true cause is essential before pursuing treatment. Symptoms can vary widely, and early evaluation improves outcomes. Take a free, instant, online symptom check to better understand your signs and get personalized guidance on your next steps.

Explanation

Hair loss in women with PCOS, or Polycystic Ovary Syndrome, is often linked to hormonal changes. Androgens, which are male hormones present in both men and women, are typically higher in women with PCOS. These hormones can cause hair follicles to shrink, leading to hair thinning and loss.

Factors Contributing to Hair Loss:

  1. Hormonal Imbalance: High levels of androgens can interfere with the normal hair growth cycle, causing hair to become thin and fall out.
  2. Genetics: Family history can play a role in how PCOS affects hair growth. If hair loss runs in the family, it might be more likely to occur.
  3. Inflammation: Inflammation in the body, which can be associated with PCOS, might also contribute to hair loss.

Managing PCOS through lifestyle changes and medical treatments can help manage these symptoms. If you're experiencing hair loss or other concerning symptoms, you can check your symptoms with Ubie's free AI-powered assessment tool and discuss the results with a healthcare provider for advice tailored to your individual needs.
