I have very dark hair that was gray or white temples time to. I have tried many colors and always respected it that my hair because it is very fine not damaged. even with colors from the hair salon, I was not satisfied. this hair color of khadi is just great. the application is super easy. I always do this alone. it is very productive and adapts to my natural hair color to perfectly, while the white hair is super covered. if you still the amlershampoo of khadi USER, then holds the color super long, with me the gray then after about 6 weeks to come slowly. the hair is very well maintained. the only thing is that the first 3 days after the hair dye smell very musty. but only in the wet state.
