Good with reservations

I am not a fan of bottles I cannot see through. Could not tell how much product i had left. This morning all that came out was the oil side. Disappointed that the white cream side was empty. Would not buy again for that reason.

This saved my damaged hair

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! 💆‍♀️✨

[This review was collected as part of a promotion.] I used this on the ends of my hair as my ends felt very dry. It definitely helped! My ends look healthier! Love the smell of this product too!

Well worth it!!!

This is one of my favorite products! I have used it for years and leaves my hair super soft and shiny.

Texture game changer

I love this product! The best for applying when I have time to let my hair air dry. It’s like neosporin for your hair!

Originaly posted on  kerastase-usa.com

Not impressed

Smells great, but leaves my hair feeling strange and I don’t really notice it’s any shinier. I feel it’s overhyped

Originaly posted on  kerastase-usa.com

Great for winter

This is a great product for leave in during winter. I have fine hair and not to heavy.

Originaly posted on  kerastase-usa.com

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.

Originaly posted on  kerastase-usa.com

My favorite

I live this. It is my most favorite. It makes my hair softer, skinnier, less frizzy and frazzled.

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.

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!

Love it! The best styling product.

[This review was collected as part of a promotion.] I am a 40 years old guy with a dark brown, low faded cut hair. I use the BAIN FORCE ARCHITECTE collection. The shampoo, the mask, conditioner, the leave-in hair & scalp SERUM EXTENTIONISTE, and this the Sérum Thérapiste Hair Serum, because i wash my hair every day, blow dry it and straighten it. My hair does not look damage or unhealthy whatsoever with the daily 430 Fahrenheit straightener. And i use this serum to style my hair when i feel like to have a wet hair look, or the hair & scalp serum for a damp soft hair look. Just love it.
