It makes your hair not frizz. Amazing scent. As a heat protectant for straightening, it doesn't do much though

I feel mediocre about this product.
I have dry, thin, damaged hair from styling. It's like I'm cursed.
Let me start by saying that the scent is perfect! It's like wearing something expensive. It helps my hair look slightly more shiny, but it does nothing for frizz. As soon as I step out into humidity, especially on the day I've washed my hair in 10 minutes, they start to puff up.
As for heat protection, I can't give any criticism as my hair is already damaged :)
It's too expensive for nothing, in my opinion.
Personally, I prefer the same company's genesis defense thermique. My hair hardly frizzes at all and I love it.

It does what it promises. I use it in combination with the discipline mask from Kerastase. However, if I go outside and walk around while there is a lot of humidity, my hair still frizzes.

I only have good things to say, it has a fantastic scent and does what it promises! It leaves the hair very soft, helps with straightening, and protects it. After about a month and a half, I don't see any damage from heat at all, which I usually see. It also has a lightweight texture, I don't feel my hair heavy at all like with some other products I have used. I will definitely buy it again!

Really good product. It helps with frizz and leaves the hair silky. You can notice the difference as soon as you apply the cream to your hair. The only downside is the price. The whole range is very expensive.
