Hair thinning with PCOS

If you have polycystic ovary syndrome, thinning hair at the top of your head is one of the most common and least talked about symptoms. It usually shows up as a widening parting, a see-through crown, or a ponytail that’s got thinner over a year or two. Unlike shedding after a baby, this one doesn’t stop on its own.

Why it happens

PCOS raises androgen levels — the hormones that in higher amounts shrink hair follicles on the scalp. Each hair grows back finer and shorter until some follicles stop producing visible hair at all. Doctors call it androgenic alopecia or female pattern hair loss. The same hormones are why PCOS can cause acne, and extra hair on the face or body while the hair on your head gets thinner.

What it looks like

Gradual, not sudden. Thinning at the crown and along the parting, while the hairline at the front usually stays put. No bald patches, just less density. It often runs alongside irregular periods, weight that’s hard to shift, or skin changes.

What actually helps

Because the cause is hormonal, the fixes are too — and they come from a GP or dermatologist, not a shampoo. The common options are the combined pill, anti-androgen tablets such as spironolactone, and topical minoxidil. Managing insulin resistance through diet, exercise or metformin helps some women. Ask for blood tests to check androgen levels, thyroid and iron, because low iron makes it worse and is easy to fix.

Why tracking matters

PCOS hair loss moves slowly, and so do the treatments. Nothing shows a change in under three months and most take six. Without a record, you can’t tell if the pill is working, if minoxidil is doing anything, or if it’s quietly getting worse. One photo of your crown and parting each month, same light, same angle, is the only honest answer. It also gets you taken seriously — because “it feels thinner” gets dismissed and twelve months of photos doesn’t.
