I have had premature grey hair since I was around 12 to 14.... I started using hair color around 24. Now I am 34 and I think have more grey than black though I frequently color. I am fine with it... I am concerned about my two kids 2 and 7. From their hair texture they have not inherited my genes but how do I take good care of their hair and prevent premature greying. .. It's too early yes but any hair care tips would help
