My daughter developed one white hair when she was 7 yrs of age. I pucked it to see whether its really white...and I found so. For 2 years I did not find any white hair. Now again recently, she being 9 yrs, I found white hair on the same spot as before. I need some solution or answer....whether the greying is premature and so would increase with time or the white hair would disappear in time. I look forward to some answer
