I haven't ever felt a product really warranted taking the time to write a review however, this shampoo is incredible! I've had dry, frizzy hair all my life and I have only ever managed it by straightening it within an inch of its life, causing it to be even more dry and damaged. After using this shampoo, I can now mostly rough dry it and then spend 5 minutes with a round brush smoothing it over! I used to spend at least 45 minutes blow drying and straightening my hair before this shampoo. I love all Kerastase products but this one is definitely the most effective for my hair!

This shampoo is now the only shampoo I will use on my hair. I love the smell while im using it and how my hair smells when it is dry. My hair is strong and healthy and the anti-frizz works really well

It did leave my hair soft but I have quite thin frizzy hair and it didn't control it very well. I think it is for more coarse hair.

I bought this shampoo for my frizzy hair, being a more expensive shampoo and with the good reviews I purchased it in hope that it would make my hair more tame. I used it for a good few weeks but saw no improvement in my hair, it made it even more frizzy if anything. Definitely wasn't worth the price, and I wouldn't recommend.

Just love this shampoo - have been using it for a number of years and I still can't believe how good it makes my hair look and feel.
