Shocked my stylist
I started using this when working on repairing straw dry blonde ends. This product is truly a game changer… and I’ve tried a lot of products. After 3 months of using, when I went to see my stylist for a trim and highlight refresh, she commented on how much Heather my hair was especially the damaged last three inches of my hair.

So far so
I highlight my hair so am really concerned about breakage, especially for the baby hairs around my face. So far this treatment has really helped. I feel the amount seems small for what you pay, but it seems to have worked compared to other brands as well.

Not as expected
I had high hopes but turns out that my hair ends remain open and split after use. The hair doesn’t loook better and is frizzy. The Kérastase oleo relax oil serum is much better and the LOreal El vive no haircut cream is also better and at a fraction of the cost.

A Miracle for Damaged Hair!
I’ve been using the Kérastase Résistance Thérapiste Hair Serum for a few weeks now, and the results are truly impressive. My hair was feeling brittle and lifeless from years of coloring and heat styling, but this serum brought it back to life. The dual formula (serum + cream) feels luxurious and absorbs beautifully without leaving any greasiness or weight.
After each use, my ends feel sealed and smooth, and there’s a noticeable shine and softness that wasn’t there before. It also protects well from heat, which is a must for me. I use it on damp hair before blow drying, and sometimes a tiny bit on dry ends for extra nourishment.
If your hair is damaged, over-processed, or just in need of serious repair, this is absolutely worth the investment. It’s like a spa treatment in a bottle! 💆♀️✨

It is indeed like neosporin for the hair.
I don't use it all the time but always keep this in my beauty arsenal. Great if I have to wash my hair more frequently or when it is frazzled from hot and humid weather. It instantly de-poofs and deeply moisturizes. My hair goes "ahhhhh" after I apply it - shiny smooth with renewed movement and bounce. I rub this between my hands and apply this on my dry hair where it needs it.

Great Product - Leaves Too Much in the Bottle !
As much as I like this product - it is great for my thick hair - it is very expensive and after the pump stops working I can feel by the weight that there is still a good amount of product left in the bottle, but unfortunately there is no way to open it. I am throwing away at least 2 more applications, which is a waste and doesn't make me happy.

Good product
I like this stuff. It’s a two in one serum and cream. I have very fine thin hair and it doesn’t weigh it down.

Absolute Must Have
I can’t live without this product. It not only protects and leaves hair soft, but somehow gives my hair a healthy texture.

Helps hair look healthy without weighing it down!
[This review was collected as part of a promotion.] This is a product I’ve used for years. The only reason I didn’t give it 5 stars is due to the price and the container…one side of the serum runs out before the other sometimes. It’s great for my dry, highlighted hair.

Great for split ends
[This review was collected as part of a promotion.] This is a great product for split ends. I originally bought it as a serum to use all over my hair, but I should have read the description better. My colorist let me know this is more for the ends of hair, and to get an oil for all over. It works great for what it is meant to and I love this line!
