I have always had naturally curly hair. I have never used dies or anything like that because I was afraid it would just ruin my hair. I have had enough issues with it being naturally curly and frizzy already, I didn't want to risk losing my hair, as well. I began taking a daily supplement which has really helped improve the quality of my hair. I really have to be careful in what I eat or my hair will pay the price and I have found that making sure I get enough vitamins and minerals that I really need can be very challenging at times. I do know that my hair and skin pay the price when my body is out of sync.
