A miracle worker. Nothing beats this when it comes to smoothing frizzy hair - it's the only product I've ever found that makes my hair look and feel like I've been to the hairdresser. It doesn't weigh down fine hair, just makes it beautifully sleek and soft. I hope it is never discontinued.

This was highly recommended to me as a heat-styling protectant. I have fine, slightly wavy hair that's down to the middle of my back. It's currently been about a year since my last haircut (I know) and I have a ton of split ends. I don't expect any styling products to heal them, but this does make my hair feel very soft and healthy looking. Also, I love the scent. It's a bit pricy, but I'd repurchase.

I have straight, fine textured, just past shoulder length hair.
I HATED this product. I ended up with tangles and dryness.
Ironically I love the Kerastase Nutritive Nectar thermique, even though it is not meant for my oily hair type. I have gone back to this.

If I should choose one staple hair product to use for the rest of my life it would be this. I consider Kerastase products quite expensive but I wanted a great product to prevent heat damage and after reading so many reviews I bought this one. Win!


Let me explain: I have long curly coarse hair- and lots it- that I straighten 1-2 times a week (it's too time- consuming for every day since it takes a whole hour and a really hot flat iron) This process can be very damaging too. Here comes Ciment Thermique.


After washing my hair and conditioning I apply one and a half hazelnut size amount at the ends of my hair and whatever is left throughout the rest of it and massage. I like the fresh smell and the gel texture that doesn't feel sticky and spreads effortlessly. Then comb, blow dry without brushes and straighten with my flat iron (for an hour as I said before!)


Results: Silky smooth, glossy, bouncy, healthy- looking hair that reflect the light like never before! I'm convinced that it can not be only science, it's magic!
Even the next day, I just slip the flat iron once more quickly and they look sooo beautiful!
With this rate the 125 ml tube lasted over a year, so even though it's not cheap by any means it's true value for money. A little goes a long way, you don't have to use any anti- frizzing serum or glossing mist and the protection lasts even through a second wash.


Now my hair is almost waist long- and they have never been that long before. I get split ends after all of course, but hey, they are definitely less than before. I love Ciment Thermique, without it I would never know how beautiful my hair could be!


Update: over a year later I still use it and still believe it's awesome! I was given Nectar Thermique as a gift though - I'll test it properly and add the comparision.

my hair was frail & get static but with using this in conjunction with the green bottled shampoo, conditioner, and mouse my hair is in much better condition..how this acts on its own with other brands i don't know, im sure its just as good but my hair is def better using this brand and i am def buying it again when i run out..don't expect miracles but my hair is def in better condition from using it continued >>

Loved this styling lotion as a heat protectant before flat ironing and found that it also keeps the frizz at bay. Has a light citrus scent and worked better on my medium-fine, dry, colored hair than Nectar Thermique. Would repurchase.

Phenomenal - best out there. Lasts forever. A huge impact on my hair's appearance.

This product is just amazing! I always get compliments about my hair even without styling. Or should I say combing? hahaha! My hair feels smooth soft, and bouncy every time I apply this leave-in conditioner. <3 <3 <3 continued >>

The only part of my hair I use my iron on is my fringe, as I like to have it super straight! I was using John Frieda straightening cream. It was really good for straightening, but not so much for protecting. The ends of the hair on my fringe was damaged, hair was split and it was really visible. I went to a hair dresser and bought Ciment Thermique. It's a really nice product to help prevent the damaging a flatening iron can make to your air, it smells nice, you need a tiny amount and it gives shiny and healthy hair. The only thing that bothers me is that it doens't prevent your hair from frizzing when it's wet outside, or when it's hot and you sweat...

Makes the hair so soft, and it protects really good from the heat. A bit expensive though.
