Resistance Sérum Thérapiste - Doble serúm termo protector-renovador de fibra

I love this product, I have been using it for month and to me is the best for dry blonde hair, my hair now is bright, no damage at all. I recommend 100%. I actually use all kerastase products

Working wonders for me!

I bought this because my stylist told me it will help with the breakage from bleaching my hair (previous stylist left me under the dryer for too long) and after just a few weeks my stylist has seen significant improvement! I'm not a huge fan of the scents of Kerastase, little too florally for me, but I do like this product.

Good!!!

So far so good helps with dry brittle hair I love it . A bit pricey but I I’ll be checking out there other products .

Great product, horrible packaging

love love love the product but hate the packaging! Each time I've gotten this it feels like I'm throwing away half the bottle b/c one side is still relatively full but the other side is empty and hence nothing more comes out. Even if I could take off the lid to get the rest I'd be somewhat happy, but you can't. That kills me.

MUST HAVE PRODUCT FOR DAMAGED HAIR

Decided to give this a shot one day and it’s an absolute game changer! Never has my hair felt so soft without going to the salon until I started using this!

Great product!

After using this product for a few months I’ve noticed my hair feels and looks healthier.

Good product but overpriced for 1oz

It a pretty good product leave your hair super soft not sure if it working but the price is way overprice for 1oz only reason I don’t think i would repurchase unless it on sale

A must have, get it!

This serum has definitely transformed my hair. My hair is so soft and hydrated now. The pump system could be better and the bottle does not last very long but for me it’s worth it due to the positive change in my hair. So glad I found Kérastase products.

Can't do my hair without this

I have damaged hair and I use this after shampooing and leave in and it detangles and leaves it soft and shiny!

Hello Hydration

LOVE this product, I have dry, heat damaged hair that’s so thirsty for hydration, and this product adds just that! It’s not heavy or greasy, just hydrating and my hair feels amazing after I use it. Also the smell is amaIngggg! I do agree with other reviews that the pump system and dual serum is a bit strange, but I haven’t had a problem with the pump and I just mix the two serums in my hand before applying to my hair.

Great product…Bad pump system

Such a bummer to write this but the pump cr*pped out on me and one side stopped working (the white cream) after only like 4 uses. I felt like even after one use it was working (softer ends) but they need a better system so people don’t return these.

This serum is a life saver and the whole line has changed my life. I recommend this to anyone with EXTREMELY damaged hair. This is not for lightly damaged hair. You will excperience weigh down and all the moisture will probably change your hair texture. My hair is naturally curly and was damaged from bleaching from black box dye to bright blonde, then dyed back brown twice bc the first time the stylist made my hair a horrible burgendy color not chocolate brown like i asked...thr blonde process took over a year. Then add all the heat damage. My hair is breaking off and i want to try to salvage my length. First let me say...if you have curly hair...do not go blonde. It will kill your curls and you will have to constantly straighten your hair ending up with crunch fried lengths...not even split ends. I love Kerastate and decided to try the extremely damaged hair line. My hair is so damaged that protien treatments wont work...its past that point. So i did not excpect it to work so quickly. Ive used it twice and my hair is already soooo much more manageable and soft. I use the shampoo and leave it on my hair for 2 mintues, then use the mask. I love the mask but it doesnt act like a conditioner on my hair so i wash the mask out after 15 mintues then use Oribe hair alchemy conditioner, leave it on for 2 mintues and rinse...but if they had a conditioner with this line i would use it. After that i spray my hair with Matrix protien builder, then use the kerastase extreme length and damage serum( smells sooo good and works even better). After, i apply the kerastase damage repair heat protection cream and oribe blow out cream, blow dry on low heat at the roots til 80% dry...then use my revlon blow out brush on LOW...its waaaaay to hot to use on high. It will fry your hair. I probably caused alot of thr damage with that tool using it on wet hair and on hot. Make sure yoir hair is 80% dry. On dry hair i will also apply the serum before bed and wear a bonnet
