PCOS and hair loss: tracking the thinning

Thinning at the crown or a widening parting — sometimes called female-pattern hair loss — is one of the harder PCOS symptoms to notice, because it happens slowly. Logging it won't regrow hair, but it gives you something a single anxious moment in front of the mirror can't: a dated record of how it's actually changed over months.

Why PCOS can thin your hair

The same higher androgen levels involved in PCOS can act on hair follicles on the scalp, gradually shrinking them so hair grows back finer. The NHS lists thinning hair and hair loss from the head among the main symptoms of PCOS. Unlike a receding hairline, this androgenic thinning usually shows first at the crown and along the central parting — which is exactly why it's easy to miss until it's noticeable.

What a severity log changes

Hair loss is slow, so memory is an especially poor witness — 'I think it's worse?' is hard for a GP to act on in a ten-minute appointment. A dated 0–3 severity recorded weekly, ideally with the odd parting photo, shows direction and pace. That helps your GP decide whether to check androgen levels or other causes, and it makes a follow-up six months later a genuine comparison rather than a fresh guess.

What's worth recording

A weekly 0–3 for how thin or shed-heavy your hair feels is enough to sustain. Note where you notice it — crown, parting, temples — and the date. Many women find an occasional same-angle, same-light photo of the parting more telling than any score; the diary is for the trend, not the panic.

PCOS Diary logs hair-loss severity in one tap, week after week, and turns the trend into a doctor-ready PDF you can bring to your GP.

Common questions

How is PCOS hair loss different from normal shedding?
Everyone sheds hair daily. PCOS-related thinning tends to be a gradual, ongoing reduction in density at the crown and parting rather than a temporary increase in shedding. A dated log over months helps tell a steady trend from a passing phase.
Should I track hair loss alongside other symptoms?
Yes. Hair loss rarely travels alone in PCOS — recording it next to acne, excess hair growth and cycle changes gives your GP the fuller picture they need to decide what to test or watch.
