My hair has never been this soft. Seriously this is the best treatment I’ve ever had on my hair. And I can do it at home in my own shower.I Love This Product !
This conditioner, as well as the shampoo have become my new favourites. My hair is in much better shape overall - stronger, fuller looking, shiny, soft and bouncy - all achieved with minimal fuss! If considering trying these products, please don’t let the high-ish price put you off, as the results together with the need to use just a small amount of product will put you in front after just the fir...Read MoreSo good!
I LOVE this conditioner, as well as the shampoo from this range. It’s helped bring my dull, frizzy and damaged hair back to life. It’s even helped my hair grow. I’ve had a lot of friends comment saying my hair looks longer and I have this range to thank for that. I keep coming back to this conditioner because it is worth every cent!So good!

I love this range so much! My hair is extremely damaged and continuously snapping and this shampoo and conditioner have seriously changed my life! The tiniest bit goes the longest way, it smells delicious, leaves my hair SO soft and feeling super strong. I have noticed a significant difference with the overall reduction of breakage and the general health of my hair. This product is amazing and I ...Read MoreProduct worth purchasing
A perfect companion to the Kerastase shampoo in the same range. A little goes a really long way and a bottle lasted me approximately 7 months (for shoulder length hair). The difference in my hair makes the price completely worthwhile and a product that will be on purchase repeat!Worth the money
I just started using this condition as well as the shampoo and I absolutely love it! The smell is devine and it leaves my hair feeling soft and manageable. A little goes a long way so definitely worth it's price.Improves the hair
This conditioner is an absolute saving grace for dry hair and split ends. It worked really well for my when I dyed my hair blonde. It nourishes and really hydrates the hair.Great for fine damaged hair
My hair dresser refereed me to the Kerastase range, at first I was a bit hesitant due to the price but I can tell you its worth it. I was worried it would be to heavy for my fine hair but its perfect. I have really noticed a difference in the strength and length of my hair since using it.Best conditioner
This makes my hair so soft and lovely. I have been using it for a few months now and my hair has never been better. I love it!Beautiful
Makes my hair so soft. Smells great too. Love Kerastase productsworth it
I've been using this product, along with the shampoo for a few months now and I have really noticed a difference. The only issue is that I find myself using a lot more of the conditioner than shampoo, I find if I put this in and comb through my hair while the conditioner is still in, I use a lot less and it works betterBeautiful conditioner
This is a very lovely conditioner that is very thick and oh so moisturising. I love how it smells and makes my hair feel afterwardGood,
NGood, not great
Since kids, I have baby hairs growing and bald patches in other places. I was looking for a shampoo that was light and would help repair my hair. I have dry but oily hair, that I straighten daily.
I bought this with the matching shampoo. This shampoo is good, not the best Kerastase shampoo I’ve used- same as this conditioner. Hasn’t helped with hair growth (didn’t think it would thou...Read MoreLightweight conditioner
A lovely lightweight conditioner that still packs a punch. I switched over from using a Kerastase Masque as a conditioner, and was worried this one wouldn't be rich enough but it does the job without weighing hair down.Absolutely divine, thick and luxurious, smells delish
I had recently struggled with thinning hair especially on one side....After many tests etc it was put down to hormones (ovarian cyst) etc wreaking havoc on my body. Lack of iron also but I felt that even after this diagnosis my hair needed a helping hand to return to my mermaid locks that I have always had. I am 37 so age is also a factor but my amazing hairdresser put me onto Kerastase range. I a...Read MoreLovely Conditioner
This is a lovely conditioner, it smells so good and makes my hair feel more hydrated. I have fine, long, bleach damaged hair so I am trying to restore its health, and this is definitely helping!Great for Healthy Strong Hair
This Conditioner used with the Shampoo is Great for growing your hair. helps add length whilst keeping hair super healthy and strong. I use this Shampoo & conditioner all of the time and i refuse to use anything else. LOVE IT!Super Hydrating
This alongside the Shampoo make a great combo together. Having extremely blonde hair i was needing a change in products.
With the winter months my hair felt dry and needed moister. I was recommend this product by a group of friends.
I use this twice a week and the difference my hairs feels already is amazing.Kérastase Résistance Extentioniste Fondant Conditioner 200ml
Been using only for a week and have noticed a difference...feels healthier...
I have coloured hair and it feels good...will purchase again...:)Not 100% sold
I bought this conditioner, and the matching shampoo because I wanted to grow mermaid long hair. I'm not convinced it helps with growth or hair strengthening, and to be honest, I feel that the conditioner doesn't leave my hair as smooth or conditioned as other products. For the price, I just don't feel it's worth it.Beautiful
I started using this product as it was recommended by my hairdresser to give my hair some extra love between my appointments. I use this in conjunction with my Olaplex treatment and this leaves my hair feeling so strong and smooth. I have long thick (but fine) blonde wavy hair which can be quite unruly and prone to a lot of breakage and I have found this has given my hair a lot of life and hydrati...Read MoreBest product for blonde hair
I have dry blonde hair, well used too. After using this product suggested by my housemate/hairdresser my hair looks like I don’t dye it - it’s that healthy and shiny now. Honestly worth every cent and it lasts.Worth it!
This whole range helped my over processed hair feel good again! Definitely worth the priceHOLY GRAIL!
GUYSSSSSSSS!!!! Doesn't weigh down my limp hair, adds the most beautiful shine and hair feels 100% healthier! LOVE IT!Incredible range of hair care products
I’ve been using this conditioner along side the shampoo for over a month now and I have to say it’s most definitely helped my hair. It’s worth every cent in my opinion. Both shampoo and conditioner has lasted me over a month of use. I have oily, dark hair that needs frequent wash and with using these products I’ve noticed I only need to wash my hair every second, third day now. My hair looks and f...Read MoreGreat for over processed hair
This whole range is great for seriously bleach damaged hair. Expensive but you really can notice the difference10
best products ever100% worth the price!!
This conditioner is amazing! I have the shampoo to go with it and after years of bleaching and damage from heat my hair feels soft and silky and smooth. 100% worth the pricetag!! The only down side is that it doesnt come.in a bigger bottleAlot of product required
I found that I needed to use quite a bit of product in order for it to evenly go through my hair and therefore it doesn't last long. Still smells nice and is effective. I just didn't find it to be very cost effective compared to other conditioners.Very happy with the Range!!
My hair was highly damaged after going completely blonde last year due to over lapped colour which caused my hair to snap!!
I have been using the Kérastase Résistance Range since November and have noticed a rapid growth in my hair especially the hair that had snapped and the conditions has definitely improved!!Very happy with the Range

I purchased this conditioner with the matching shampoo from Kérastase. Whilst I didn't really love the shampoo, this was a really nice conditioner. Not too sure if it help lengthen my hair as it claims, but it did feel really nice and kept my blonde, dry hair feeling soft and beautiful. Even still, I actually much preferred the mask, so if you are tossing up between the two, go for the mask!Decent conditioner
Moisturising conditioner. Bit pricey. Not sure how much it helps with strengthening hair. Hair feels softer and manageable after using it.Good but pricey
I love this conditioner. It is not too thick, but conditions the hair very well. Only issue is the high price.Nice conditioner that leaves hair soft and healthy
I have just started using this with the shampoo of the same line.It doesn’t give hair the same instant ”wow how soft” effect as some others, but i feel like it’s more of a good thing, because it means there’s less silicones in it. Overall my hair does feel healthy and looks moisturized but not weighed down.Will buy again
A little goes a long way with this conditioner which egrets considering the price. Leaves my hair softNot the best product.
While it does help hair feel smoother, it failed to help promote fast hair growth like the others claims. Other cheaper conditioners which are on the market which do a better job.Good Conditioner for Lengths
I like this conditioner, and my hair ends are being kept in good shape as I'm trying to grow it out.
It smells lovely and I find that it is very hydrating without needing too much product.
I would recommend this over the more expensive masque.
It is light, which is good for fine hair, though I must note is not brilliant if volume is what you want.
Because of this, I chan...Read Moresmoothness
I actually didnt believe in this product but after trying it out and seeing the results i'm amazed.A must have for soft and healthy hair
I have tried many different Kerastase ranges. I have enjoyed many of them, however the extentioneste range is by far my favourite. I have highlighted, quite dry hair and this has completely transformed the look and feel of my hair. I did use this in conjunction with the shampoo and extentioneste serum and will continue to do so for a very long time. It is heavy enough to eliminate any knots bu...Read MoreDidn't like it
This conditioner left my hair so dry and horrible! I've been reading the other reviews and i'm left so confused because I just want to throw my bottle out. I am not using the matching shampoo so maybe that has something to do with it but my hair has never felt so dry and hard. Not soft, feels like i've put a whole heap of hair spray in my hair and tried to brush it out. Really disappointed.Love this product!
Great rich and creamy product. Excellent for damaged hair, my hair feels much softer and hydrated after using and I don't have to wash it as much! Love this productvisible results
I have thick, wavy, virgin European hair that I slaughtered with heating products my entire life leaving it coarse, brittle and split.
I’ve been using the extensionist range for 3 months with 2 trims in between and my hair has never looks healthier or grown faster.
Everyone has been complimenting my length while I’m enjoying how much healthier it looks and softer it feels.

I love the smell of this leave in cream. It has light hydration and protects hair when blow drying. My hair is fine and I find this does not weigh it down.Just get the mask instead
The results from this conditioner are great & it works well with the matching shampoo but like another reviewer said you need to use a lot of it! A little does not go a long way! I definitely wouldnt buy this again, I would just go for the mask instead or use a different conditioner. I have long, highlighted hair but even my husband who has normal hair says he had to slather loads on!Great Lather and Smells Amazing
I love using this product. I have really dry damaged hair and used to get a lot of dandruff. Since using this product it has disappears and my hair is so much easier to manage. I use a small amount to begin with, then wash it out and use about a 50c size worth and it lathers amazingly. I will continue to buy this product, haven't been using it long enough to see rapid hair growth but am content no...Read MoreSmooth Hair
This conditioner leaves my hair silky smooth and it has been damaged a lot from bleaching. The only down side is the price and I usually need to alternate between this and the masque as I tend to use a lot of this product so it runs out quickly. Will continue to buy as I am very happy with the result.Amazing!
purchased on a whim and on my second bottle now. Best conditioner I've used. It has stopped my hair breaking dramatically. My hair feels stronger and much healthier!Ok
Ok product, my hair felt good but the price is a bit steep. I would mix it up with a less pricier product and use this 1-2 times weekly.Worth it!
This product is worth the splurge! it really has strengthened my hair and allowed it to grow long in a short amount of time. My hair is nourished and moisturized without feeling greasyGreat
Moisturises, but not greasy.Smells nice
This product smells so nice and is worth all the hype my hair feels so repaired after using this
