Why PCOS causes hair thinning
PCOS can cause thinning of the hair on the scalp, often called female pattern hair loss or androgenic alopecia. It's driven by higher levels or effects of androgens ('male' hormones), which many women with PCOS have. This typically shows as thinning through the crown and part line, rather than a receding hairline.
It can be genuinely distressing, and it's a valid reason to seek help — not something you have to just accept.
What can help
Several approaches can help, ideally guided by a doctor. Treating the underlying hormonal picture matters — options can include certain combined pills or anti-androgen medications, which reduce androgen effects. Topical treatments like minoxidil can help regrow or thicken hair. Because iron deficiency and thyroid problems also cause hair loss and are common in women, checking for these is important too.
Results take time (months), so patience and consistency matter with any treatment.
Get the diagnosis right
Hair loss has many causes, so it's worth confirming what's driving yours rather than assuming. A GP can assess your hair loss pattern, check bloods (including iron, thyroid and hormones), and tailor treatment. If PCOS is the cause, managing it more broadly often helps your hair along with other symptoms.
If thinning hair is bothering you, a telehealth consult is a supportive place to start and arrange the right tests.
