Wondering why this brand is so coveted...this shampoo is not great. I always see Kerastase with the highest prices in stores and have thought they must be a luxury hair care line. Welp this shampoo did nothing special for me. At most it gave me a little boost at the roots, but my ends looked totally fried/dried out. Tried to use some glossing on my ends to mask that, but ultimately would not persuade me to buy this shampoo. I dont know if its loaded with parabens or alcohol or what, but I cant stress how disappointed I was in the results. Especially since I have always wanted to try one of thier products. Perhaps they make one better formulated for normal or dry hair, but my hair is oily at roots and tends to be drier on ends. SO I dont use any drying products or too moisturiuzing shampoos for this reason. My take is a big MEH. Smells nice though.
