text: is it normal if a child begins to grow grey hair? well i'm not a child anymore i'm more of like a teenager but when i was eight years old, my hair began to grow grey hair (i have black hair). i never coloured my hair because my parents are afraid that if i coloured my hair it would ruin it and my grey hairs would multiply, but it is multiplying anyways. as of right now my hair isn't actually fully grey but there a lot of it that some people can see it. i didn't do anything about it so i've had it for six years now, but i've always been curious if it is normal. some people just get grey hair earlier than others.  its not abnormal.
