I love this shampoo, it really strengthens my fine hair and I combine it with other shampoos from the same brand. I really like the strength it gives me and I've been using it with the conditioner for a while now.

Kerastase never disappoints. I've been using this or a similar Kerastase shampoo for a couple of years now for blonde hair, highlights etc. and it leaves hair looking great!
