And if so what did you do about it? I had a single blonde hair turn up when I was about 15 (my hair is dark brown) which scared me, and my first white hair turned up when I was 23. I'm now 28 and have obvious white hairs scattered throughout the dark ones, and seem to be trying to grow a white streak at the front. I occasionally think about dying my hair black, which I've wanted to do for years, but I'vee never got around to it. Aside from that I'm firmly in the 'leave it alone' camp as I love the idea of having white hair.
