Fast results

I've been using this product for almost a month, didn't get the chance to use it much but from what I've used it's the fastest product in terms of seeing results on my hair. My hair is noticeably better especially my brittle ends they seem very healthy and shiny, most importantly my hair is no longer breaking at length. The smell is very nice and the shampoo is very foamy giving you a very fresh and clean feeling after use (unlike some greasy type of shampoos). Would definitely go for the kerastase extentioniste gamme for my hair care!
