What kind of hair color you would suggest. I use loreal hair color and loreal color protect shampoo. But this shampoo does not protect for more than 10 days. Somebody told me that my hair growth is fast so it is often that when new hair grows from the roots they are gray that's what I use frequent color to cover those gray hair growing from the roots. I can't stop my hair growth but if I can protect my color please suggest.
