Hi I am max Sunsilk black is a shampoo which claims that hair becomes shiny and straight hair and 12 hours proction but I thinks they only claims high bt it cant be possible for them to develop such high kinds of chemical and shampoos , bt the worst think is that this shampoo is none of use and having many side effect my siters and mom used it and they experienced that their haors are greying then it seems the hair is whitening and falling rapidly , the life of hair is decreased so I don recomend this brands shampoos
