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.

It lasts for a long time!

You don’t need a lot of it to wash your hair and the smell is great. I don’t think it truly helps your hair grow but it does leave it looking healthier.

Greasy build up

I usually buy kérestase Bain de force and have used that for about 10 years. I have hip length bleached hi lights so need a good shampoo and conditioner to keep my hair in good condition. I thought I’d try this for a change but I’m disappointed. I usually shampoo my hair twice and then condition and rinse well once a week, twice tops. With this shampoo I always find my hair looks very greasy/waxy by the next day. It also gave me a flaky build up on my scalp that I have never had. It was like cradle cap. I’ll be going back to Bain de force with my next order.

Love this range

Really lovely shampoo, I have the conditioner in the same range too. Always come back to Kerastase if ive used something different... my hair is blonde and requires some strength so this is ideal for me. Hair always feels so fresh and soft afterwards. I shampoo twice and then condition.

Great shampoo

My hair feels SO soft after using this shampoo. I use straighteners and I am hoping to grow my hair so hopefully this will help.

Good but not much lather

Not much lather to this which took some getting used to but I feel like this is really helping to repair my hair. I use the whole range and when I used my old stuff for one night I really saw the frizz return! Will buy again. Only need a small dollop

Pleasant shampoo

Purchased this product after years of using the brand. Happy with it overall. Great smell as with all their products and only need to use a small amount for adequate coverage on long hair.

Disappointing after long use

I've been using this shampoo together with a matching conditioner for many months. It was okay in the beginning, but with time the scalp became greasy the next day after washing, so I had to switch to a different brand.
