Rated 3 out of 5 by from Good product, prices takes too long I found this Kerastase Gondant Renforcateur to be a little too time consuming for me. I prefer to have my shower and go but this product requires you towel dry your hair apply, let sit and then get back into the shower to rinse. Having said that, it dud seem to work as even after the first use I saw less hair from breakage in my brush when I brushed out my hair. It also has a pleasant enough scent. If you have all the time in the world to use this product properly, it is worth purchasing. Unfortunately I do not.

Rated 3 out of 5 by from Nice, but not quite right for my hair! Instructions on the container were easy to follow. I have thick hair (partially fine strands mixed with coarse) prone to dryness and found that I needed to use a lot to have it spread throughout my hair. I didn’t mind the scent. It was a bit strong (perfume) when applying but smelled lighter and pleasant when dried. I left it on my hair for the time specified. It rinsed out quickly. I found that my hair was quite shiny but it tangled too easily. I had to add a product to keep it from continuing to tangle. I normally do not have to add that step after conditioning. I had enough to use a few more times during my normal every other day hair washing schedule and I tried it on my daughters hair too. She has a different hair type. Finer hair and average thickness. It worked very well for her and no tangles. I feel it didn’t suit my hair type but I did notice a little less breakage. My daughters hair was lovely.

Rated 4 out of 5 by from Great strengthening, average detangling I have been using this conditioner for 2 weeks on my long, slightly wavy hair that is prone to breakage. This conditioner has a nice, light scent and rinsed out well. My hair seems to be stronger, with less breakage of individual strands than before I tried using this. There seems to be less hair breaking off when I comb it and during showers. It feels nice and soft, with lots of body once dry. However it does not seem to do as good a job of keeping my hair tangle free as other conditioners I have used. It is also a little more effort to use than other conditioners as well, as the bottle states to towel dry your hair and then apply and leave on for 2-3 minutes. I’m used to the leave on part of the equation, but I’ve never had to stop my shower, towel dry my hair, then apply conditioner. For an occasional deep condition this would be fine, but for regular, daily use this is not really practical for me to continue doing.

Rated 4 out of 5 by from Great Conditioner! Really made my hair soft and shiny and while I’ve only used it a few times now I do feel like maybe my hair is breaking less!! I like this conditioner a lot because I bleach the heck out of my hair to get it the colours I like!

Rated 4 out of 5 by from Would use again I was not really a fan of the smell. It did leave my hair less frizzy though. The consistency was nice also. Wasn’t so thin that it fell off the hair while sitting

Rated 4 out of 5 by from Fantastic for colour processed hair I recently coloured my hair and I was glad to have Kérastase Fondant Renforçateur on hand to use afterwards. I found it was an excellent treatment to return moisture and softness to my hair.

Rated 4 out of 5 by from Bye Bye Dry Hair! I have been colouring and flatiron straightening my hair for years. The split ends were so bad my hairdresser said they were the worst she has ever seen them. After trying the Kerastase Fondant Renforcateur only once, my hair felt softer and smoother. I'm definitely going to keep using this! I'm sure the next time I visit the salon, my hairdresser will notice a difference!

Rated 3 out of 5 by from Too much of a chemical smell! I have used this product a few times now and do not like the product. I find the scent is very strong, even after you wash it out. It reminds me of the chemical smell of a perm. It stays in your hair basically until you wash it again. The product does make my hair feel soft but less than a day and my hair starts to feel heavy and greasy. I usually only wash my hair every couple of days or so but find I want to wash my hair everyday because of the way the product makes my hair feel after a few hours. I will keep using the product to see if it makes a difference to the damage my hair has but I will not be purchasing this product or recommending it to anyone right now. I may post another review if I find it helps with the damage my hair has. Hopefully, they will make it less scented in the future.

Rated 5 out of 5 by from Silky and Shiny I really enjoyed sampling this product. My hair has been dry and frizzy lately from over straightening and stress. I used this Renforcateur twice and it really improved the texture of my hair - silky and soft. The shine was phenomenal and no tangles when blow drying.

Rated 2 out of 5 by from Not good. I really wanted to like this product because it is exactly what my hair needs. It smells great and the consistency is good, but it left my hair feeling stiff and almost.... sticky? It made it very hard to manage and brush.

Rated 3 out of 5 by from Good product! The product worked well in my hair. I also used it in my son's 4A type curly hair. It worked well to soften the hair and keep frizz out. My hair felt smooth and healthy after use. I would recommend this product, however it does contain some ingredients that can be drying for curly hair

Rated 5 out of 5 by from Exceptional results after one use! Having only used the product for week, I am seeing the deep conditioning effects of Kérastase Fondant Renforçateur. My hair was revived after only one use. The product left my fine hair soft and very manageable, without the weighed down feeling of some conditioners. My hair was easy to style and even looked great the next day. I can't wait to see the benefits after continued use of this product and if minimizes breakage over time. Thank you Home Tester Club for the opportunity to try this product. I will definitely purchase this product!

Rated 4 out of 5 by from Noticeably softer, smoother hair! I loved the way it felt in my damp hair! It was easy to work through to the ends and I just knew it was going to make a difference! My hair felt noticeably softer and healthier after using it!

Rated 4 out of 5 by from Overall liked this product I have tried this product once since receiving it. I thought it had a nice smell. I have long colour processed hair. I expected my hair to be easier to comb through while wet as I have previously experienced with other conditioning treatments but I didn't notice that with this product. However, after drying my hair felt quite soft and smooth and the product left a really nice smell. My hair also feels light without any heavy product residue.

Rated 5 out of 5 by from It works! And it smells great! The first thing was the fragrance. The smell is suttle. But very pleasant. It was easy to apply and I found a little went a long way. The fact that you are to towel dry your hair before applying is a pain. It was easy to rinse out. Left my hair feeling soft and my hairbrush easily went through my hair. I will be buying this product.

Rated 5 out of 5 by from My Hair Feels New! When I tried my Kerastase sample I was wondering how well it would work, so my first night I tried it, I opened it and squeezed some in my hand for my first use, the fragrant was awesome, it felt heavy in my air so it worried me how it was going to be when my hair was dryed. As my hair began to dry I could feel that it was softer. Once my hair was dry completely I was amazed that it felt good. I brushed it and I thought it felt heavy, but continued on day at work. During the day, I felt my hair and it didn't have any fly away hairs, it kept its place and it wasn't dry, I was totally impressed. I used it again the next night and I got the feeling my hair is much more healthier. Now I would not want to be without it, as I can tell that my hair has improved, the damage is reversing and my hair is so much healthier.

Rated 5 out of 5 by from Amazing This conditioner is amazing! You need very little, doesn’t leave any residue, doesn’t make your hair look greasy, super soft and easy to brush! I even use it on my 5 year old daughter!

Rated 4 out of 5 by from Great conditioner from Kerastase The texture is creamy and the scent is delicate, nothing to dislike. The product is easy to apply and the 2-3 minute wait is very reasonable. Product rinses off easily without leaving any residue or greasy finish on hair. My hair was well hydrated, easy to detangle and soft to the touch.

Rated 5 out of 5 by from THE HAIR CARE PRODUCT EVERYONE NEEDS! Let me start by saying that my hair is thick, dry, wavy, damaged and prone to breakage. Due to this, it’s hard to find the a single product that will do everything I need for my hair, it usually takes 2-3 products (on top of normal hair care, like shampoo and conditioner). I’ve spent more time and money than I care to admit looking for a GOOD product... I’ve happy to say, I’ve found it in Kérastase Fondant Renforçateur. Since I started using it my hair is softer, shinier, healthier and more manageable. I’m finding it easier to style my hair and I’ve even noticed that I have less buildup, maybe because I’m using less product, and I can go longer in between washes. Best of all, I’ve been able to get rid of the other products I was using, which saves me time and money. I’m also buying less plastic/packaging. I’m certainly going to continue to use this conditioner as part of my hair care routine.

Rated 4 out of 5 by from Nice soft hair I am a curly girl and as such I am careful what goes into my hair. I don’t follow the method strictly and so I decided to give this a try. It smoothed my hair and made it more manageable. It also didn’t flatten my curls. I really liked it and will use it again :)

Rated 5 out of 5 by from Soft, soft, soft hair! This product is amazing! Hair felt amazingly soft to the touch, easy to brush and smelling oh-so-delicious! Will definitely buy this product again. I have very fine hair and usually hair products tend to leave it heavy... not this one. Kerastase Fondant Renforcateur left my hair feeling soft and light. LOVE THIS!

Rated 4 out of 5 by from Definitely works I received this from Home Tester club for review. My hair is extremely dry and colour treated. I used this several times and I really like it. It made my hair really soft and less frizzy. I also really enjoy the scent. Kerastase is a really trusted brand so im not surprised that this is a really great product.

Rated 5 out of 5 by from Finally Tame Hair! At first when I put the Kérastase Fondant Renforçateur on my hair, I noticed the citrus smell. It went on my hair almost like a paste, and I was concerned about this. However it rinsed off nicely, and I was surprised right away, as usually when I rinse my hair and pull fingers through hair, I lose strands, I did not! I have thick crazy, frizzy hair and after it dried, I had comments on how tame my hair looked. I also noticed that I was not losing hair like I usually do. I was very impressed and will be purchasing it again.
