Strengthen and protect strands with the Kérastase Resistance Serum Extentioniste, a nourishing leave-in hair serum that helps to protect against breakage. The non-greasy formula uses a host of powerful ceramides to seal the hair cuticle whilst a blend of lipids creates a smooth surface, creating a fortifying effect from the inside out.
The highly concentrated serum forms a defensive barrier over the scalp to protect against damaging environmental aggressors, whilst also sweeping away impurities for a fresh appearance. Hair will be boosted, revitalised and given improved resistance.
No rinse. Apply to wet or dry hair and scalp and massage scalp. In case of contact with eyes, rinse them immediately and thoroughly.

Lovely scent
Bought this to see if it would be a replacement for the Initialiste…which I can no longer find! The consistency almost seems identical along with the smell. Some more added ingredients, but I’m hoping the effect is the same, as the initialise was fab! So far, I’m liking this product and it is non greasy!

Perfect finish
Being using for a number of years and really like the finish it gives my hair! However I do admit, the consistency does not stretch as much as you would expect so you end up using more

Great smell
I bought this serum to use it in addition to the shampoo and the mask. Smells great but too early to see and difference.

Not as expected
Being so expensive I haven’t seen much of a difference with this serum
Did you find this review helpful?
No visible results
Nice smell and texture, but I haven’t had any visible results. Cheaper products work as well to be fair. Not worth the money in my opinion.

Very good
It helps with strengthening the roots a lot. I used the whole line of product.

It works!!
I’ve been using this for several weeks now and can see an improvement to my scalp and to my hair. Might be to early to see the full results but I will definitely buy again!

Very good
I buy this a lot as it leaves a lovely tingling sensation on the scalp too which is good for stimulating hair follicles. One of my favourite serums to keep scalp and follicles healthy.
