One of the things that can contribute to grey hair is a lack of zinc in the diet. Most American diets are low in zinc. Get yourself some multivitamins that have minerals including zinc. Can't hurt you and if it helps, Hurrah! In my early 30s, my income was rather spotty and there were times I couldn't afford vitamins. I found a hair that was dark at the ends and grey in the middle. I do have a few sparkles of grey now, but my hair is still dark and I will be 59 this year. No Lady Clarol for me- I take my zinc!
