Reading the signs
Temples, parting, ponytail: what your hairline is telling you
Most women describe hair loss as one thing. In clinic it is at least four, and the place you noticed it first is the most useful piece of information you have. Here is how to read it.
The temples: the corners of the hairline
The corners of the front hairline carry the highest concentration of androgen receptors on the scalp. When the oestrogen that normally shields those follicles falls — sharply after a baby, then slowly through the late thirties — they are the first to feel DHT, the hormone that miniaturises follicles. That is why so many mums notice the corners first: the bun exposes them, and the school-run photograph confirms it.
What it tells you: this is hormonally driven and it is not a nutritional problem. No supplement changes what happens at a DHT-sensitive follicle.
The parting: a line that became a stripe
A widening parting is the same process seen from above. The hairs along the parting are not falling out en masse; each is being replaced by a slightly finer one, and from directly above — the kitchen spotlight, the car, a child stood on a chair behind you — a field of finer hairs looks like scalp. This is the pattern most often dismissed as “you’ve always had a wide parting”. You have not; look at a photo from five years ago.

The ponytail: the bobble that goes round one more time
If the bobble wraps three times where it used to wrap twice, you have not lost a third of your hairs. You have the same number of follicles producing thinner fibres. The ponytail is the most honest measuring instrument you own, because it measures total volume rather than what you can see in the mirror.
What it tells you: diffuse thinning across the whole scalp, again driven by miniaturisation. It also explains hair that has gone limp, will not hold a style, or has gone dry and straw-like — a miniaturising follicle produces a poorer fibre as well as a thinner one. More on texture change here.
The brush and the plughole: shedding
Shedding is different from the three above. It is a growth-cycle problem: hairs are being released early, before they have reached full length, and the follicle then sits idle for longer than it should before restarting. You can shed heavily for a long time before any of the patterns above become visible — which is why the plughole frightens women who look, to everyone else, exactly the same.
What it tells you: the growth phase has shortened and the resting phase has lengthened. Stress and sleep loss do this through cortisol; hormonal decline does it through oestrogen. Mums typically have both.
Why this matters
Every one of these patterns comes back to the follicle, and the follicle is dealing with several things at once: a lost oestrogen shield, DHT, reduced blood supply, low-level inflammation, and missing growth signals. A product that addresses one of them produces a partial result at best. That is the whole story of why the shampoo, the gummies and the roller did not work, and it is the subject of the next article.
