Tracking hair shedding in perimenopause
More hair in the brush, a widening part, a ponytail that's lost circumference — midlife shedding is common, distressing out of proportion to how casually it gets dismissed, and worth a real workup rather than a shrug.
Why it shows up now
Estrogen supports the hair growth cycle; its decline shifts follicles toward shedding and finer regrowth. But the differential is famous — ferritin (drained by years of heavy bleeding) and thyroid are the two checkable causes on every list, which is exactly why they're on Perity's.
How to track it
- Slow-moving: log monthly-ish impressions and notable events (a shower-drain day), not daily counts.
- Same-part-line photos on a schedule are the gold standard of home evidence.
- Log the checkable context: recent illness, weight change, new meds, iron-draining heavy cycles.
What a useful record looks like
A months-long dated record with photos and context — plus ferritin and TSH results logged in Perity — is the difference between 'my hair is falling out' and a workup that starts at the second appointment instead of the fourth.

Questions
Is hair loss part of perimenopause or something else?
Often both candidates at once: the transition shifts follicles toward shedding, while low ferritin — years of heavy bleeding will do it — and thyroid disease produce the same picture. Those two are blood tests, which is why the honest first move is checking them rather than assuming hormones.
How do I track shedding without obsessing?
Monthly, not daily: an impression entry, a photo with a consistent part line, and honest notes on context. Slow symptoms want sparse records — the pattern lives in months, and Perity keeps the dates straight.
