Kerastase is the best hair product at Lookfantasic. Especially, this product is so good. It is easy to use and is frequently used. I am happy that I like my hair.

Great product！after rinse it off,my hair feels softer and smoother than ever

I got a lot of help in improving my hair.

The Kerastase dynasty has many personalities - some are dull, some are limp, some are not so young and worse for wear - and, wow! Chronolgist reverses time, not unlike Botox for the skin. I have curly hair. It used to be thick and vibrant. It is now dotted with grey and dry and dull. But NOT when I use Chronologist - I then catch a glimpse of younger, more vigorous hair that sparkles under light. Thanks Kerastase for letting us, the not so young, feel a bit as if we were in our twenties again!
