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.
This product was by far one of the best that has come in my box! I loved it and plan on buying a full size version!5
This stuff not only smells good but also makes my hair really soft, hoping it will really help for the long term.4
Kerastase Resistance Ciment Thermique is one of those products you didn't even know you needed! It is completely amazing. I have very fine hair so it's hard for me to find a leave-in conditioner that actually works without weighing my hair down. This stuff is GOLD! I'll never use anything else ever again. It smooths, assists with styling, and makes my hair SUPER shiny all without weighing it down. My favorite Birchbox product so far!5
This product smells amazing - citrusy/lemony. However, I don't stray from my normal hair products. I also don't really use heat for my hair, so I don't need it.2
I love KÃ©rastase products and this one met my expectations. It smells great and made my hair feel more soft.5
Im not sure if I like this product or not. Im going to have to use it a few more times to see if Im seeing any difference.3
I already have a heat-activated conditioner I love, but this one is worth trying! I liked the smell and it left my hair super soft and shiny.4
This product left my hair greasy. I tried it a second time with the same result :-(3
I am a hairstylist and have used MANY leave in conditioners before. This one is one of the best. It goes on like a dream, smooth and non tacky. The smell is great, super light and pleasant. It doesn't weigh the hair down at all and can be used as a great base for other styling product.5
I had been using a protective product on my hair, but it wasn't working. I still noticed split ends and breakage, I use a flat iron on my hair 3-6 times a week. This product works great and has improved the health of my hair in the short time I have used it. This product also lasts a long time, I only have to use a dime sized amount each time I use it. The sample size has lasted me for the last 3 weeks.5
