My friend gifted me the shampoo and conditioner set. I’ve now brought this big bottle because it’s so good! Makes my hair feels light, smooth and keeps it tame, also noticed A massive difference in how healthy my hair looks after using! 😍😍😍

Always loved Kerastase products but this is my favourite shampoo (good for long hair) and great to have in the bigger size as much better value!

Smells incredible like a hair salon! Results are not disappointing as it reduces breakages and gives your hair a boost to promote hair growth. My hair is super long but I use it to maintain my ends

My hair was so damaged and weakend as never. I was concentrated on buying different hair treatments as masks or pre-masks thinking that shampoo is not so important. When I tried Kerastase Bain Extenstioniste I saw the difference! Even the result after the same hair masks I have used before is much better when I use Karastase Bain Extenstioniste together with them. I like this shampoo so much that I ordered it again. After some time I tried to use other shampoos again and the result was not so good. So I have ordered it 500 ml because I realize it is my must-have! Just with it my hait looks healthier, softer and nourished.

I am a professional hairdresser working in a salon with kerastatse and this shampoo is amazing for long hair to keep healthy and long. When I saw this amazing price I had to purchase it to try myself and I love it!!!

This is the best shampoo I've ever used for my long hilighted hair.. it smooths the cuticle and gives a good clean while keeping hair supple and strong.. I've been using it for over 10 years (it used to be bain de force). I swap for different brands every now and then for a change and it's always a relief when I use this again 01
