Repair and moisture

This product has helped repair my dry damaged hair. I put two pumps in and it immediately sucks up the moisture. When I don't use this product my hair tangles more easily and is frizzier than normal.

Healthy looking

I’ve been using Therapiste for years. Nothing compares.

Still the best....

I have fine hair and am always amazed at how beautiful it looks after I use this as a styling aid. Shiny! Bouncy! And amazingly full too. Hard to get all of this in one product. Have been using it for a very long time and keep coming back to it as there is no better. Sure, I do use a mousse sometimes when it's very humid out and I need that extra oomph, but, otherwise, this is my styling go to.

Smooth, soft and healthy

I love the Kérastase Résistance Thérapiste Hair Serum! It makes my hair feel smooth, soft, and healthy, especially at the ends. I’ve noticed less breakage and my hair looks shinier and stronger. It’s lightweight and doesn’t feel greasy, so I use it every time I style my hair.

Smells great works great

[This review was collected as part of a promotion.] Truly smells soooo good and makes my hair feel so soft. One of the rare products I've found that feels worth the price. I just wish the packaging was more efficient - it feels like it's 80% bottle and 20% product

Not sure it does anything

[This review was collected as part of a promotion.] I have tried this a few different times but ultimately come to the same conclusion that I’m not sure it is actually doing anything. It’s nice to use before blow drying my hair but can be a little heavy if you accidentally use too much.

AWESOME BUT SMALL

I just love this serum. You can use it before and after styling and smells wonderful. The only downside is that it didn’t last me through not even 3 weeks. I would definitely purchase it again for its quality but I need something more budget friendly!

Magic In A Bottle!

Love, love, love this serum! I have noticed a big difference in my ends. I have heavily highlighted hair that suffers damage and the occasional breakage from highlighting. I have been struggling with split ends for years and this serum has helped with the beginning stages of repairing them. I use it after every shower and notice that my blowouts are a lot smoother and my split ends are way less noticeable. My hair feels stronger, healthier, and less dry. This will definitely be a repeat purchase of mine!

Repairing my dry breaking hair

This product is definitely healing my damage. Going from over bleached hair I have a lot of thinning and dryness that break off as I brush. I will keep repurchasing! Formula is slightly thicker than I’d like for my thin hair but it still gets the job done & don’t over use it!

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.

Originaly posted on  kerastase-usa.com

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.

Didn’t help with damaged hair

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.
