What should you know about PCOS and hair loss?

PCOS can involve higher androgen activity, which may gradually make scalp hairs finer in people whose follicles are sensitive to those hormones. The thinning may be most noticeable around the parting or crown, while facial or body hair growth can also change. A PCOS-related pattern is not the only explanation for scalp shedding or thinning.

A clinician may ask about menstrual pattern, acne, new facial hair, recent illness, weight change, diet, stress, medicines, and family history. Examination helps distinguish diffuse shedding from patterned thinning, smooth patches, scalp scaling, or breakage. Possible alternatives include female pattern hair loss, telogen effluvium, alopecia areata, traction alopecia, or scalp ringworm.

Arrange an assessment if thinning persists, spreads, or is affecting your confidence. Bring a list of medicines and supplements, and note when the change began and whether it followed illness, pregnancy, a major stressor, or a change in periods. Gentle hair care and avoiding tight styles can reduce added stress on fragile follicles.

Treatment depends on the pattern and on wider PCOS symptoms. Your clinician may discuss scalp treatments, hormonal options, or management of an identified deficiency or trigger. Finasteride is not suitable for everyone and needs careful discussion, particularly when pregnancy is possible; do not start it without medical guidance.

Seek prompt assessment for sudden patchy loss, painful or inflamed scalp, pus, heavy scale, broken hairs with sores, or loss of eyebrows or eyelashes. Arrange medical review sooner if hair loss accompanies rapid new facial hair, deepening voice, or other swift androgen-related changes. A scalp infection or inflammatory condition may need treatment rather than cosmetic care alone.

Does my pattern look like hormonal thinning, increased shedding, breakage, or a scalp disorder? Which examination or tests are appropriate? How might my period pattern, acne, or unwanted hair guide the plan? What treatments are safe if I am trying to conceive or could become pregnant?
