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.

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!

Clean, soft, and healthy

Brilliant staple shampoo, does exactly what it claims. Used for over a year and when I have been tempted to try a new launch Kerastase Range, I’m not left as happy and come back to this shampoo and conditioner combo. I would say the combo does help hair to grow because I do notice roots quicker with my blonde highlights when using this range. My hair type is fine but a lot of it, that dries curly if left to air dry, and length is just short of my bra line. Because of exercising I wash my hair every 2 days but this combo helps to keep my hair from root to tip healthy, and feels clean and soft after washing, is non greasy, and gives decent volume.

Mixed feelings

Im not sure how I feel aboutthis shampoo. It’s been brilliant for the first couple of uses but now it builds up a lot and leaves the hair greasy. I might give it a break and start using it again later.

Works well on fine hair :)

I've been using Resistance Bain Extentioniste for the past 8 months and feel it's made a big difference to my hair (my hair is mid-length, fine and colour-treated). Along with the shampoo, I also use the conditioner and serum. My hair is stronger, breaks far less frequently and, although it grows painfully slowly, it IS growing! The serum is particularly great - even my hairdresser has noticed a considerable difference in the quality of my hair at the roots. I should point out that along with this range I have also limited the use of heat on my hair, taken regular supplements for hair/skin/nails and applied Kerastase Elixir Ultime Rose (which smells fantastic!) to the ends/lengths. All of these elements have boosted the health of my hair and cause it to feel stronger. The products last a long time (particularly the serum - I've been using it for 8 months and have only used around 1/5 of the bottle). I've just placed my third order for the shampoo/conditioner and I use them several times a week. I would definitely recommend!

Effective.

This crystal-clear liquid smells lovely and has a very light texture. It cleans very efficiently and is also very good value for money.

Brilliant product

This product is brilliant and keeps my hair lovely and soft. This range has less protein in so doesn’t irritate my scalp as much (the higher protein content the more I get a flaky scalp) so I use the whole range and love it. It cleans my hair beautifully and leaves it bouncy and shiny and totally manageable.

Not for greasy hair

This was good the first 2-3 times but now after about 3 weeks my hair is a greasy mess, with roots that feel waxy! Will stick to Bain Satin 1 in future. My hair is bra strap length, fine but dense, and wavy
