Rated 5 out of 5 by from Extentioniste Family of Products I made a decision to get my hair healthy again, which is not easy nearing 50 years old with long hair. It was either a cut I didn't want, or invest in something wonderful. I used Kerastase prior, loved it, and this was the only suite of products that I would invest in again. I have stuck with the Extentioniste family of products now for 120 days and my hair health is top notch - length, strength, and look is amazing. Try it, stick with it, it will not let you down. Shampoo, Fondant Conditioner and Mask + Thermique and Elixir. Alternate Fondant, Mask, and Elixir as needed and you will find youth in your long hair. Thank you so much Kerastase for making these great products.

Rated 5 out of 5 by from The best professional products for hair. I have been a faithful customer of Kerastase hair products for years. My hair is so much healthier because I buy and use the best hair products that can be purchased without having to go to a high-end hair salon. The results of healthy, shiny hair is proof enough for me that I will continue to use your products.

Rated 2 out of 5 by from Smells good I bought this a month ago from my salon. I had high hopes for this product but unfortunately it leaves a horrible build up in my hair. I’ve tried to reduce the amount I was using as well and I ended up with the same result. Totally bummed.

Rated 5 out of 5 by from Best all around conditioner I first found this conditioner around 3 years ago and haven't found anything that compares. It makes my fine, highlighted hair soft with defined waves without being heavy or greasy.

Rated 1 out of 5 by from Tangles hair This is my first purchase of a Kerastase conditioner. The brand always seemed so luxurious, but I really wanted to strengthen my hair so I splurged on this conditioner. This product was so disappointing. I have long, fine, salon-color (red)-treated hair. This conditioner caused my hair to knot in the back and did nothing. I used it 3 times hoping for a change, but it did not work. I would definitely not buy this again; and now I'm hesitate to try the brand again since it was so expensive.

Rated 5 out of 5 by from OMG! This transformed my hair!!!! So, my hairdresser recommended that I explore Kerastase since his clients have reported that their hair has transformed while using this company's products! I decided to use the diagnostic tool to determine the best products for my thick, color-treated hair. I purchased the Bain thermique shampoo along with the conditioner (the extension version), and ciment thermique (the heat protectant) and all three have transformed my brittle, dry nest into a glossy, gorgeous set of locks after the first use! I have used other high-end products which have costed much more, and was disappointed. Kerastase is different! The shampoo and conditioner are so concentrated, that you only need a little bit per wash or styling. Provided this, I can justify spending the money since these products will last a long time! My split ends even look sealed and I found my hair was easy to brush through, and blow-drying time was cut in half! These products took the My hair looks as if it was just styled professionally by a hairdresser. I have received compliments from everyone. Since I believe in these products so much, I sent the complimentary samples to my mother to convert her! Since my first purchase, I have since purchased the hairspray, the initialiste, and also the bain architecte mask! I am so in love with Kerastase -- you saved my hair!!!! I am a now a loyal Kerastase lover!!!

Rated 5 out of 5 by from The Perfect Remedy for Dry Summer Hair I have long thick hair and the summer often leaves it dry and damaged. Between the sun exposure, chlorine from pools and salt from the ocean, my hair is often left feeling very dry by the end of August and in search of a product that will bring it back to life. Kerastase Resistance Fondant Extensioniste Conditioner has become my new remedy for my dry, rough summer hair. A conditioner that you leave in for a few minutes and then rinse out, it delivers on smoothing out my dry hair and helping the hair to feel soft again. It’s easy to use and does not weigh my hair down or make it heavy. I love that it has helped to restore my hair to its normal condition and I highly recommend it.

Rated 2 out of 5 by from First time user I tried kerastase resistance conditioner along with the shampoo for the first time although it smells good and has a good light consistency . After use I did not feel a difference in my hair and required more conditioner to help detangle it . I must add I have very curly hair .

Rated 5 out of 5 by from Kerastase Conditioner 1st and foremost I have dry curly hair that frizzes easily and is colored. Also it breaks pretty easy too, so I tend to co-wash it or wash it once every two weeks with a shampoo and condition it non stop. Kerastase to me is known for their products on a higher end with salon quality. I was ecstatic to give this a whirl,especially since it's supposed to help with hair that seeks a healthier length (hello breakage). This conditioner is supposed to be a GENTLE restorative conditioning creme. Having my type of hair I'm always on the look out for good condiotners. This is also supposed to help with detangling and nourishment for improved longer, stronger hair. PROS- Smells Good. Less is more. Felt conditioned right away. Really did untangle my hair. Hair felt so soft. Was manageable. CONS- pricier side. Wish it was a tad bit thicker consistency...This product made my hair look and feel amazing. Hair was soft, smelled great, felt soft and was untangled when I got out of the shower. I usually use a but didn't need to which is definitely a plus especially with curly hair since less products are better with curls. The only thing that would make this better is if it was a thicker product and maybe at a decent price point. I will absolutely purchase again. If you have hair that is dry, coarse, tangled or just want longer locks- this is the product for you. I only needed a little bit of this to smooth through my hair and was shocked at how smooth ,less frizz,no tangles and how my curls fell. Love this duo and would love even more if they added a deep conditioning mask to this line. I'm sold.

Rated 3 out of 5 by from An Ok Conditionee While the conditioner did make my hair feel clean, I felt it did nothing to soften my hair after use. My hair felt way more coarse and tangled than normal. I should note I have extremely long hair, not sure if that has any affect on the outcome of the conditioner, but I feel this is just not for me.

Rated 5 out of 5 by from Strength to reach new lengths!!! I think Karastase Resistance Fondant Extensioniste conditioner is absolutely a luxurious spa treatment for your hair!! This conditioner feels so silky and fondue like in your hands. Then once you run it through the lengths of your hair you can feel it instantly transforming your tresses into smooth tangle-free strength that will stand up to blow drying and styling while protecting your precious ends so they can grow long and so strong!! Love this product!!! 5 stars!!!

Rated 5 out of 5 by from Works Great! I Love It!!! The Kerastase Resistance Fondant Extentioniste Conditioner is awesome! I just loved how it smoothed my hair giving me the most perfect curls. I have natural curly hair and it is to my waist. It made my curls look so pretty. I had no frizz at all. It smoothed out my broken ends. It has detangling and nourishing forces that improved my hair and made it stronger and gave it longer hair length quality. It made me feel wonderful by giving me healthy beautiful hair. I really think you should give it a try and see for yourself. I believe it will make your hair healthy and make you feel wonderful too!

Rated 5 out of 5 by from Great for summer hair I'm very particular about which hair products I use on my naturally curly hair, but I gave this conditioner a try. It really felt like my hair was moisturized just after one wash; almost as if it corrected the damage done by the summer sun and weekends in the pool.

Rated 5 out of 5 by from Kerastase Extensioniste conditioner This was my first time trying kerastase and boy oh boy they went beyond my expectations! I just love thhe smell and the feeling my hair gets afterwards is unlike any other conditioner Ive used. I dont get that oily feeling just like smooth and sleek. I already feel like my hair is a bit stronger with just 2 uses. A+++Highly recommend

Rated 4 out of 5 by from Excellent product This product was a great for my long (mid-back length) hair! It left my ends feeling hydrated and soft. I was worried that it would be too heavy but it was light and made my hair easy to style.

Rated 4 out of 5 by from Healthy hair! I really love how Kerastase Resistance Fondant Extentioniste Conditioner made my hair feel super healthy and shiny. I recently started to dye my hair. I've had blonde hair all my life and figured it was time for a change. But that also means my hair isn't as healthy as it could be hair dye is hard on my hair. I used this shampoo and conditioner combo and I fell in love immediately. The only thing is i wish it smelled a little better. I want too crazy about the smell of the shampoo. But it still worked awesome!!!

Rated 4 out of 5 by from Nice conditioner This conditioner has a nice consistency, not too thick or thin. It left my hair soft and smooth without feeling too weighed down. I cannot comment on it improving the length or strength of my hair as I only got sample sizes.

Rated 5 out of 5 by from Extreme Conditioning The Kerastase Resistance Fondant Extentioniste Conditioner is by far the most luxurious and best conditioner I have ever used. It was creamy, thick, and smelled amazing. I applied it evenly over my hair and I could feel it working. The tangles came loose from my wet hair as I was applying the conditioner. Even though the conditioner feels thick in your palm, it feels light in your hair. After rinsing, my hair felt clean, super soft, and light. I towel dried my hair and was able to pull a brush through my hair with ZERO tangles. As my hair air-dried, I noticed less frizz and fly-aways. After my hair was completely dry it was definitely less frizzy and much, MUCH more manageable. I will definitely use this conditioner again and would highly recommend it.

Rated 5 out of 5 by from No frizz!! I was a little hesitant when using the shampoo and conditioner, but I cannot say enough how much I love it! I didn't blow dry my hair after I showered, and it dried wavy. Absolutely no frizz!!! This shampoo/conditioner combo is the product I've been dreaming of! I have naturally wavy hair and have to use so much product to control it. Not with Kerastase! I'm in LOVE!

Rated 3 out of 5 by from It’s okay at best My hair length is almost at my waistline and the bottom half of my hair is frizzy and dry. I wasn’t a fan of the scent it left behind, it was almost like a light salon chemical and it lingered all day but it eventually fades out. It did smoothe out my hair but it’s the like it left my hair feeling silky soft. It was easy to apply and you do only need a small amount to get it evenly thru out your hair even with my length. Honestly I just wasn’t impressed, i felt like it was pretty average.
