It does absolutely nothing for frizz. Maybe it helps as heat protection... maybe not, and that's not even certain. Money wasted.

After observing that my hair was extremely dehydrated, I chose this Kerastase range (in combination with the shampoo and conditioner). After using it for 2 months, the hairdresser told me that there has been a significant improvement. My hair is very fine and colored.

mediocre to bad product! It doesn't deliver at all what it promises! The only good thing is the scent it leaves behind

I really don't know how many times I have bought it in the last 8+ years, I don't change it. It smells refreshing grapefruit, has a gel-cream texture and doesn't weigh down the hair. It really reduces heat damage.

It protects the hair and leaves it smooth and soft after drying and straightening with a hairdryer. It improves the appearance of damaged and worn-out hair.

Very good product that helps hair during the use of a hairdryer and scissors for curls.

I have colored hair and I am very satisfied.

Excellent product. I have highlighted, damaged hair that tends to frizz. With Ciment Thermique, straightening becomes very easy, hair looks smooth and healthy, and the result lasts much longer.

Indeed one of the best products on the market! It keeps its promise and heals the hair. I apply it on damp hair and then use the blow dryer for better results! It's worth the money.

For hair that has undergone bleaching, it is just what you need, it leaves them very smooth. For healthy hair, I would not recommend it because it can make them greasier
