Rated 5 out of 5 by from Creme de La creme I used to use all kerastase products before and I switched for a while. Recently I re ordered this shampoo along with hair mask in the black container and ciment thermique and it made me realize that I should have never stopped using kerastase. My hair is softer than ever and more shiny! Kerstase really is the crème de La crème

Rated 4 out of 5 by from Smells great I purchased this a few weeks ago. I switched over from the genesis anti hair fall line because this was suggested when I did the hair diagnosis tool on their webpage. It is supposed to also prevent hair fall as well but I don't think it works as well as the genesis product line, my hair is moderately damaged from when I had bleached my hair 3 years ago and I do have hard water. I also noticed with the previous product it did take almost 2 months to start working so i am hoping that after a few more washes it will start preventing hair falling out as well. They are pricey but the last bottle lasted me 7-8 months( I wash my hair once a week) Other than that I think its a great shampoo, smells nice, makes my hair look great without making it greasy or dry.

Rated 3 out of 5 by from half the ingredients are just scents I would only rate this shampoo as average or fair. When you take the time to look up the actual ingredients the only ingredient that promotes growth is a castor oil. Theres some basic ingredients added in for texture, conditioning, silicones etc but then almost half the list is added for scent. I think its a very basic Kerastase formula with just some new perfumes and castor oil.... nothing special.

Rated 2 out of 5 by from Disappointing result I used the revitalizing shampoo and the extensionist serum for about 1 year and my hair is still the same length. I'm a bit disappointed. I don't know what to do to get a nice length ..

Rated 5 out of 5 by from Best brand ever I struggled with my hair all my life had to wear weave and braids to try and grow my natural hair. Since I stated using resistance i was skeptical that it won't work for my type of hair. I thought it was only for people with growing hair. Since using resistance line for almost a year now i don't wear braids or weave i have full hair health and shoulder length. Canadian winter time no issues my hair is health and I am happy with the discovery I wish that Kerastase could advertise it more because it took me time to discover this brand. Worth every dime!!
