Strengthen hair from the inside out with Kérastase Resistance Bain Extentioniste, a fortifying shampoo that uses powerful amino acids and ceramides to improve elasticity from root to tip.

Targeting weakened and brittle strands, the silky formula helps to rebuild the hair’s internal structure to make it more resistant to breakage, whilst a blend of lipids creates a smooth and shiny surface. The shampoo gently lifts away the build-up of dirt, impurities and excess oil from the scalp to leave locks fresh, clean and strong.

Suitable for weak hair types.

Brilliant

Love how clean this shampoo leaves my hair but also thick and full when dried.  Hoping that this helps my hair to grow and reach a much better condition. I have been using it for a couple of weeks so far but already I love it.

The best shampoo ever!

A year ago my hair was very brittle, thin, dehydrated, fizzy and dry. It is also bleached and I had to cut it as it looked very broken. I tried many different the most expensive brands to improvethe look of my short hair. I had a hope to grow new healthy long hair. I tried different lines of Kerastase, too. The result was always not so good, sometimes I had a little improvement but hair was always frizzy. But this shampoo for me is a miracle, I see the result immediately even if I use after different masks or conditioners of other brands. If I use different shampoo my hair looks not so alive and flexible. There is no frizz anymore. I really hope that with this shampoo my hair can grow long as I dream.

Worth every penny

I bought this as my friend reccomend it to me and she swears by it. I have highlighted hair and find my hair is extremely damaged and broken over time. From the first wash I could tell a difference in my hair from the feeling and texture of my hair. I noticed my hair was easier to brush when wet and when blow dried it was like I had just come out of the hairdresser! Highly impressed by this shampoo and I would buy again.

Trusted service

I always buy the same products suitable for my hair type. I love using their service, it’s reliable, the delivery is quick and no unnecessary bubble in the parcel (I only hope it’s the same for the other products too) Would recommend to anyone!
