Hey doc, over the last few days I've noticed 5/6 smal gray hairs on my head which has me confused and scared! I'm only 20 and have a full head of brown hair which is exactly like my dads. He on the other hand didn't appear to have any grays until about 40 and still at 54 isn only about 40% gray. My few hairs aren't noticeable unless you look very close and I don't know how long they've been there. Could this just be a temporary thing? Could it be something to do with the fact I've been a bit under the weather? Or am I going to go gray? In terms of health I eat well drink in moderation and am very much into my fitness aswell as taking multivitamins and fish oils.
