Kérastase Resistance Ciment Thermique - Prime

It’s a vicious cycle: You decide to grow your hair out, only to see it break and split so disastrously that you’re forced to get a trim. With this reconstructive leave-in milk, however, you can kiss breakage goodbye and say hello to newly lustrous strands. Formulated with heat-activated ingredients, this treatment strengthens and protects the hair shaft from the damage caused by heat styling, ensuring that your hair grows out long and strong.

Couldn't love this product more!
Purchased

I've never been a big fan of hair products because I don't like how they make my hair feel, but this product is AMAZING!!! It wasn't heavy, kept things under control, and made my hair feel great. This will continue to be part of my ongoing hair care routine.

Hair is smooth and healthier

Love this product and it has made my hair so soft and healthier. I use it a couple times a week and already see a big difference. Thanks for the new find.

Break from Ordinary

It's always hard to know if these samples work or not for the size. But it was a nice break from my usual routine. Not a big enough sample for my full head of hair!

This stuff really works to tame my snarly hair. No more knots when I go to blow dry and my hair looks and feels healthy and shiny. Recommend!

amazing

This product is awesome. My hair is so soft and I can visibly see it working on my split ends. It smells great too! A little goes a long way - I have been able to get 3 uses out of my sample.

It protects your hair from heat damage, but do not use too much!
Purchased

Overall, I think this product works well to protect your hair from the blow dryer or curling iron. However, if you use more than a very tiny amount, it turns your hair into a greasy mess.

Best Hair Treatment Out There!
Purchased

For someone who swears on using the curling iron or straightener everyday this product is magic. Leaves my hair feeling weightless and healthy! Best product I've tried (and I've tried them all).

Loved this stuff!

Absolutely loved this stuff- I've never been a fan of leave in conditioned because I always felt it weighted down my very fine but thick, straight, uncolored hair. This was absolutely the opposite-- made my hair look better than ever.

Amazing Product

All the Kerastase products are amazing. I use the shamppo and leaving in treatment daily. Sample was small as most of the Birchbox Samples have become.

Love this stuff!!

This product does exactly what it says it will do. No gimmicks, no jokes. I have baby fine hair, and at first I was using too much product and it was weighing my hair down, but I just let up on the amount I was using and was amazed how much healthier my hair was! Plus it made my samples last longer :)
