Well, a slight exaggeration, but she has 2 or 3 distinctly white hairs at the top of her head. They're also thick and wiry. I've only noticed them recently.
Any reason to worry, or is this just one of those things? I asked GP when we were attending about something else, and she just looked bemused and didn't really comment.
Is it likely to stop here, or escalate?
There is, by the way, no family history of going grey early. Quite the opposite. I'm as old as the hills and still no grey hairs at all.
