Best hair care product ever.
This gets my very fine hair to look very shiny, healthy, gives it a boost. The hair gets more volume, in short, the best thing out there for your hair!
I wash my hair daily, so conditioning is a must. This really makes a difference, without weighing hair down.
I just wish it was cheaper; since I use it so often, it tends to finish quite fast.

Worth every penny. My hair is like friggin straw, and without the use of this, I would not be happy. Detangles and strengthens hair like you would not believe. Use this with Ciment thermique- and you will be laughing. xx

This has repaired/moisturized my color treated blond hair like no other conditioner I have ever had! I also just had a conditioning treatment at the salon, but I'm pretty sure that both are working, and not just the treatment. I will update this review if anything changes. I'm definitely buying the matching shampoo soon! This stuff is expensive, but worth it. I can see amazing results. Love this!

I have long, fine, virgin hair which rarely gets heat treated, so whilst it's really healthy, the ends can get a little ratty cos it's so fine. I've just finished a tube of this (shampoo twice then apply to towel dried hair and leave for a couple minutes) and for the first month or two it was a miracle for my hair, made it thicker, shinier and healthier at the ends. My hair was gorgeous! I've never used a product that made it so perfect! I was set on buying a pro size of it. But now at the end of the tube, i've noticed my hair is starting to get drier and a little straw like on the ends... So i've stopped using it. Doesn't mean it's a bad product, just that i should've been more careful when using a conditioner that contains protein so regularly. I'll hopefully eventually come back to using this and alternate with another conditioner once my hair has recovered from the protein overload. This works fantastically well to get hair healthy if it's damaged, but be careful not to over-use it like i did.
*fingers crossed lots of moisturising protein-free conditioner will help*

I love this conditioner! A few months ago I had a terrible highlighting experience that left my hair feeling like straw. I did some research online, and decided to get this along with the rest of the "green line." My hair is finally soft again, despite being out in the sun all summer and only getting one trim to my hair. I really want to let my hair grow out and I know this stuff will help. My only complaints are the packaging and the price, but that won't keep me from repurchasing!

This product does make a difference- my hair is really damaged because i go from blonde to brown and back really often for my modelling and in the past few years especilly i have noticed my hair has been suffering. This shampoo is quite expensive but a little does go a long way and if you use it properly the results are worth it. Remember to cleanse twice ( the second time u can use a pea drop size because it lathers really well). The ciment conditioner is pretty good as well- i put it all over towel dries hair ( even near the roots because its quite light and rprevents fly aways). I do recommend this for damaged hair- blondes would benefit most as the repair is quite evident from the start- for brunettes its pretty good as well- provides excellent damage controll and strengthens and volumises nicely.

I love this conditioner... I mean it does a great job, detangles and is not heavy. Very good for everyday conditioning. Great scent! A pleasure to use. best used in conjunction with Bain the Force (best kerastase shampoo).
4 lippies due to the high price (should deserve 5 for quality)

However, for deep conditioning I prefer the mask in the 200 ml bright jar... Age Recharge that is. Damn expensive (paid it 38 Euros that is 53 bucks approx.) but very very effective.

This is ok. It's great if you combine it with the other resistance products (bain de Force + substance constructive). I wish it detangled better though. I have to use the Substance Constructive afterwards to help with that. The combo leaves my hair really soft and like velvet, so that's why I'll keep repurchasing, unless I find another cond. to take it's place.

I like this treatment, I use it once in week and keep it for 30 min. It works perfect with all other Kerastase product that I use weekly.

This is a great product and I am a big fan of the resistance line. My hair used to be a long, blonde, damaged mess! I am on my way to natural healthy hair and Kerastase has done wonders for my hair. It feels silky and soft and it looks great! I love you Kerastase, you are saving my hair<3 continued >>
