ABOUT ME: Long, straight, generally healthy virgin hair, normal amount with medium texture, oily roots and dry-ish ends.



PACKAGING: Short, fat, pale green squeeze tube with a twist-off cap. I'd really prefer a flip-top. Otherwise no quibbles.



SCENT: Kind of like sweet and fruity. Not too strong. Altogether very nice. Doesn't really linger.



USE: After washing my hair, I put a generous dollop (about 2 tbsps) into my hands and rub them together, then work the product into my just shy of soaking wet hair starting at the ends. I wipe the remaining residue on top of my head and near the hairline but I try not to get much onto my roots. Then I blow dry.



RESULTS: Amazing. I thought my hair looked pretty good normally, but it looked SO much nicer after using Ciment Thermique. My hair was glossy, smooth, swingy and felt like pure silk (but didn't look or feel greasy or gunky). It does flatten the natural bit of wave/bendiness and body, but in a good, mod sort of way. My hair looks sleek, is quite straight, and like I've just gotten a trim. It stays well-behaved all day and does not get limp or oily.



PRICE/AVAILABILITY: $36 for 125 mL. Can be purchased from the Kerastase website. It's probably safest to buy products from them directly (unless there's a licensed salon near you). Apparently there are lots of old and/or diluted products and knock-offs floating around. In the very least, buy from them directly when you first try something out. That way, if you find it elsewhere for a better price, you'll know what the packaging and product looks/smells/feels like.



REPURCHASE?: Yes. I bought this because I needed a heat protectant for the few days I need to blow dry (I try to limit heat styling) and got this due to the high reviews, brand reputation and promise to rebuild hair (which anyone with long hair should be interested in).



I'll update this review after a month or so and let you all know if things have changed.



ETA: Still using this as my heat protectant for blow-drying (I use something else for flat irons, as they're more intense and damaging). Ciment Thermique still makes my hair look and feel good and layers nicely with other products. I clarify once a week and have noticed no build-up at all. Overall, I'm very happy with this product. continued >>

It really really works. I love all heat activated products from Kerastase. This is an excellent choice if your hair is weak and yet have to style it with irons. Perfect for fine hair too, it doesn't weight it down.

This stuff is simply and utterly AMAZING! I never write reviews on things but I felt I had to with this. I have thick, frizzy hair and in all my 23 years I have rarely ever gotten compliments on it. Until I used this. I got about 5 people telling me my hair looked amazing etc. I won't go on about it, trust me just buy it!

I love this product ive been using it for years! use two a year i think, when i didnt use it for a couple of months cause i couldnt afford it i really noticed how dry and straw like my hair was becoming even though i was using a heat protector. it dosent weigh down my thin hair and my hair feels protected. i like to use a little bit extra on my ends but always comb it evenly threw the hair. i think this is one of those products ill be using for ever! LOVE

I have heavy platinum highlights. My hair was burnt and torn apart at my last haridresser visit :( My biggest problem was that I have soo little hair left on my head, not to talk about volume!! But this product gave extraordinary results as if I have too much hair on my head! I was astonished, 'cause my hair is so thickened that I look at the mirror and feel amazed each time. It did't give me silky soft hair but what I was looking for was voluptuous hair and I'm satisfied so much.

LOVE this product! I have fine, naturally curly hair with highlights so it is quite dry. Lately I have really been struggling to keep my hair healthy. I started using this product along with pureology leave in conditioner a month ago and I have noticed a huge difference in my hair.

It is expensive but I love the smell and the price is worth it since it keeps my hair healthy. Will check out the other Kerastase products.

HG material! Absolutely indespensable if you have chemically processed/weak hair. It leaves my hair silky, shiny and soft. I use it with the other products of the Kerastase Resistance range for the best result. The only downside ... it is expensive! But it lasts a long time as you do not need too much product to get fantastic results.

Despite being a product junkie I never write reviews here, but I just have to say how totally amazed I am with Ciment Thermique. Today has only been my second use, but I am already convinced that this (together with Bain de Force and Ciment Anti-Usure) is the best I've ever bought for my hair - and I've tried so many products and brands (Bumble, Redken, Davines etc.)!
After blowdrying and straightening it looks like I've just been to the salon. Beautyfully sleek, shiny, soft hair with natural movement. My fine, dry, colour treated hair doesn't feel heavy, crunchy or greasy - just like pure silk. Any other heat protector I've tried just made it stiff like straw.
With this green line I can't wait to treat my hair every day. Hopefully I will also be able to say that it has stopped my problem with breakage, I will update this in a couple of months. For now I couldn't be more satisfied with this silky, light but yet strong feeling!

Ive used better leave in moisturisers from kerastase. My hair is so brittle if I use this one alone, I still have use the aloe relax serum.
This is Just not for my hair, which is thick and very dry.

I bought this based on the positive reveiws. I have very dry colored treated hair and this just made it feel more like straw. Maybe I need to use the shampoo and conditioner that is part of this system.
