Hair thinning and hair loss in perimenopause
Direct answer
Oestrogen and androgen balance shifts in perimenopause can change hair growth cycles so shedding looks heavier or the part line looks wider — but iron deficiency, thyroid disease, post-illness telogen effluvium, traction hairstyles, and genetic pattern hair loss are also common at the same ages. A clinician can narrow causes with history, examination, and sometimes blood tests; treatment depends on the mechanism, not the age alone.

What pattern is typical?
People often describe more hair in the brush, a wider part, or a sense that ponytails feel thinner over months, not hours. Cyclical shedding linked to stress or illness can look more abrupt.
What should be ruled out?
Thyroid disorders, iron deficiency, scalp disease, and androgenic pattern loss sit on the usual differential. Perimenopause can coexist with any of them — that is why “only hormones” is an incomplete story.
How to prepare for a clinical conversation
Bring onset timing, shedding severity, scalp symptoms (itch, scale), diet changes, and family pattern. If you track cycles, sleep, or stress, include dates — patterns beat impressions in short appointments.
Preparing for care
If symptoms are affecting sleep, work, or peace of mind, use this lane to move from "noticing" to a focused visit — without skipping safety signals.
