Is hair thinning a sign of perimenopause?

Noticeable loss or thinning of hair on the scalp.

Why it happens

Estrogen stimulates collagen production and supports hair follicle cycling. As levels decline, skin thins and loses moisture, while hair follicles miniaturize. These changes often begin subtly in the early perimenopausal transition, years before periods stop.

Did you know? Less than 20% of U.S. primary care physicians have received formal menopause training — meaning this symptom is frequently misattributed to stress, anxiety, or ageing.

You are not alone
