five year old daughter with grey / gray hair

[coorong]

my daughter who is very healthy has some grey hairs (about 10) in the back of her head? Google searches bring up all sorts of worrying answers - anyone else seen similar or got any answers?

Friend was saying only 2 days ago that her 8yo DD has suddenly sprouted 5 or 6 white hairs. I said I wouldn't go to doctor just for that, but I am pretty lax and laid back and would just find the hairs curious, not a worry.

This link has loads of scarey possible causes, but all of them are very unlikely for most children in the UK (so I personally still wouldn't see GP unless something else was making me worried).
