Hair shedding vs hair loss: how to tell the difference.

Ask three questions. Speed: did this change over weeks (points to shedding) or creep over years (points to pattern loss)? Shape: is it coming from everywhere at once (shedding) or from particular places — parting, crown, temples (pattern)? The hairs themselves: full-length hairs with a small white bulb at the root are normal cycle hairs; lots of short, fine, wispy regrowth in the thinning area suggests the pattern process. None of this replaces assessment — but it tells you which conversation you need first.

Telogen effluvium — the medical name for a heavy shedding phase — commonly follows a significant event: illness (including fevers and infections), surgery, significant psychological stress, rapid weight loss or crash dieting, childbirth, stopping or changing some medicines, or iron and thyroid problems. The catch that alarms people: the shedding typically starts two to three months after the trigger, when the trigger itself may be forgotten. If you're shedding heavily now, think about what was happening around three months ago.

Usually, yes — that's the defining feature of a true shedding phase. Once the trigger has passed, shedding typically settles over several months and density gradually recovers, though full recovery can take longer than people expect and may feel slow. Two honest caveats: shedding that persists beyond several months deserves assessment rather than more waiting, and a shedding phase can also unmask pattern loss that was quietly underway — which is why the picture sometimes needs a professional eye rather than a website.

Mostly, you don't — and that's not a defeat. A shedding phase triggered three months ago is already in motion; the hairs that will shed are going to shed. What you can do: address the cause where one is found (iron, thyroid, ongoing stress, medication review with a prescriber), be gentle with what's there, eat properly, and give it time. What we'd caution against: buying an armful of products marketed at "hair fall". If a treatment claims to stop a natural shedding phase, it's claiming to stop something that stops by itself — which is also how those products collect their glowing reviews.

See your GP first when shedding is heavy and has no identifiable trigger; when it continues beyond several months; when it comes with other symptoms — fatigue, weight change, altered periods, a sore or inflamed scalp; or when hair is coming out in distinct patches rather than diffusely. (Unsure who does what? Who to see about hair loss compares GP, dermatologist, trichologist and pharmacist fairly.) These point at causes that need investigating, not treating cosmetically. A treatment clinic — ours included — is the wrong first stop for that list, and we'll tell you so if you arrive with it.

When the change is gradual, shaped and persistent — the widening parting, the slowly thinning crown, the hairline that's further back than photos from three years ago. (Noticing it early? Thinning hair in your 30s covers what's normal at that age.) That's the territory where the established options apply: assessment first, then the honest menu — every treatment compared fairly, including medication as a category, PRP where assessment supports it, and doing nothing as a legitimate choice.
