There are lot of companies and products that offer ash brown hair color. I have seen reviews of LâOreal preference and Procter and gamble and really confused. The reviews say that both the products are good, but which one is the best? I donât have the time and money to waste so I want to know from those who have ever tried any one of these products. I donât have any allergy and skin problems. So please suggest me which one is best?
