The short explanation
Scalp hair thinning is a known part of PCOS for some women. Higher androgen levels can make hair follicles on the top of the head shrink over time, so hair becomes finer and the parting looks wider. This pattern in women usually causes thinning rather than complete baldness, and the hairline at the front is often kept. There are treatments that can slow thinning and, in some women, help regrowth. These include topical treatments applied to the scalp and, for some women, hormone-lowering treatments that a clinician may suggest. Results usually take several months to show, so patience is needed.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Other causes of hair thinning, such as low iron, thyroid problems, recent illness or childbirth, crash dieting or stress, can occur alongside PCOS, so a doctor may check blood tests.
- Hair oils and home remedies are widely used but have little evidence for treating hormone-related thinning.
- A dermatologist can examine your scalp and confirm the type of hair loss.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell what is causing your hair thinning or how much it will improve. A doctor needs to examine your scalp and may suggest tests.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Is my hair thinning due to PCOS or something else?
- Should my iron and thyroid be checked?
- What treatments can help, and how long before I see results?
- Would hormone treatment help my hair?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Book an appointment soon
- See a doctor within a few weeks if hair is falling out in clumps or patches.
Raise it at a routine appointment
- Book an appointment with a dermatologist or doctor if your hair is thinning noticeably.
- See a doctor sooner if hair loss is sudden, patchy or comes with other new symptoms.
