Short answer: PCOS causes hair thinning through elevated androgens, which increases DHT sensitivity at the scalp follicle. It is the same mechanism behind male pattern baldness, but triggered hormonally rather than purely genetically.
Why PCOS affects hair
Polycystic ovary syndrome often involves higher circulating androgens, which can miniaturise scalp hair follicles over time while sometimes increasing facial and body hair growth at the same time.
What helps
Medical management of PCOS itself with a gynaecologist or endocrinologist. DHT-supportive ingredients such as saw palmetto. Managing insulin resistance through diet, which is often linked to PCOS androgen levels. And a consistent, long-term approach, because PCOS-driven thinning responds slowly.
A supplement alone will not fix PCOS hair fall. Treating hair in isolation without addressing the hormonal condition usually gives limited, temporary results.
