The next week, she asked another client. Then another. Most said yes, with relief, like they'd been waiting for someone to look at it properly.
By year one, the binder was half full. By year three, she'd started a second. By year seven, there were five of them stacked above the basins.
By 2025, Margot had 480 women documented. Every one over forty. Most in their fifties and sixties. All had tried something, usually three or four solutions and ended without a significant result.
And every one of them, at some point, had asked the same question:
"Is it just my genetics?"
That was the question that started to bother her.
But when she went through the binders properly, the genetics story didn't hold up.
Some women had mothers and aunts who'd thinned. Plenty didn't. Some had thick-headed sisters and were watching their own hair go anyway. A few had been the first woman in five generations to have anything like it.
If thinning was genetic, the binders should have sorted neatly into two piles. Family history, and not. They didn't.
But what did sort was something else......
The photos didn't look like 480 different problems.
They looked like one problem, in 480 different women.
First, the temples. Then the part that widens from the crown forward. Finally, a softness through the back where the ponytail used to sit thick.
