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.

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

Fantastic
I always buy Kérastase products as I have particularly fine and weak hair that never really grows. However, since using this product my hair has improved 100%. It hasn’t been this long and healthy in ages! Great shampoo and conditioner from Kérastase.

Strong locks
I am currently using this product and the matching conditioner, and I am very happy with the results. I love Kerastase blow dry cream so I thought I would try this to get my damaged locks back on track. I went from blonde, to brunette, to box red, back to blonde over a 4 year period. It has taken me 2 years to finally get back to a more natural blonde but my strands have suffered. Chuffed with this product as my hair feels so much healthier and I finally have got my waves back. I double shampoo and I have hardly made a dent in this bottle so it's worth the price tag.

Nice start
I have been using Kérastase Resistance Bain Extentioniste along with the same line conditioner. After several times used some improvement was noted. The hair is much softer, not tangled. Though I don't see any miracle for a while. And yes! There is a difference in the conditioner effect when you towel dry your hair after washing before applying the conditioner. I have tried both variants, it's definitely better to take off extra water from hair before conditioning. The smell is wonderful!
