So good!
Makes my hair really soft during and after my hair wash, I can feel it making my hair stronger and less prone to breakage. Don’t use too much as it is high and proteins.

Not the best
Thought I would try this shampoo for a change. Wish I didn’t, my hair was just a fuzzy mess in the morning after my first wash. If I could return it I would.

Great
My hair has oily roots but dry mids and ends, and is wavy, long, thick/coarse, frizzy and unruly. I prefer to wear it blow dried straight with the additional use of a hair straightener. My hair loves sulphates and silicones (which are both included in this shampoo).
I wanted a shampoo which would effectively clean my scalp, but not strip the rest of my hair. This shampoo manages to do this, and has also stopped my hair falling out as much when I wash it. It additionally gives me an extra day between hair washes, as it seems to control the grease on my scalp. My scalp is somewhat sensitive, but this shampoo doesn't seem to irritate it.
I use it with the Kerastase Discipline conditioner, and this combination (along with additional styling products) has given me smooth, shiny and manageable hair which resists frizz well. However, if I know I need my hair to be more frizz-resistant, I would use the Kerastase Discipline shampoo instead of this (although that makes my hair go greasier a lot quicker). I haven't tried the matching conditioner to this shampoo as I don't believe it would be enough to tame my hair.
The shampoo is expensive, but you don't need to use as much as it's so concentrated. Overall I'm really happy with my purchase, and will most likely buy it again.

Amazing!’
I wish Kerastase could do this shampoo in 500ml. My hair is very long but damaged from bleaching. This shampoo is life changing! After a couple of washes I could see and feel the difference. My hair was so shiny and manageable!

Very good shampoo!
One of the best shampoos I’ve used, and I have tried a lot! I have highlighted dry hair, which is thinning due to age I think but this has made it feel fuller and stronger. Paired with the conditioner this will become my go to hair care.

Okay
I think that it is good. I am using this for 2 weeks. So far, no noticeable difference, but also no negative effect.
