Ok mask
I got a deluxe sample from goodie bag. It’s nice and hydrating. But I still prefer to use hair oil.

Smells great, sinks in to your hair so well, a little goes a long way! I’ve used so many tubs of this and it always delivers. My hair is so happy thanks to this!great
such a hydrating mask, and does a wonderful job of smoothing frizz on my hair! be careful and only use on the ends as it can make your scalp oilyMagic
I have said bye to my split ends ever since using this product once a week for 2 months!amazing
This mask made my hair feel so sofy and shiny. Will be using again!Wow
Holy moly, I never knew my hair could feel so soft and shiny. I used a sample of this and even after the first use, the whole experience from the smell to the feel to the result is really really great. Looking forward to using this once a week. I have medium/thick long blonde hair.Noticible difference
This stuff is no joke it definitely helps with breakage and promotes hair growth. It is rather pricey, but definitely worth it if you are wanting to grow your hair without having monthly trimsDisappointing
It smells nice but doesn't particularly do anything for my hair. The consistency is thin, so I didn't expect it to do much for my hair in the first place. I used it about four times and never noticed any significant benefits.Made my hair feel like I was at the salon
Really amazing product! I like to leave it in over night/a couple of hours and then wash out with shampoo and conditioner. My hair has honestly never felt so soft!A little goes a long way!
I got gifted this beautiful hair mask and haven been using it once a week in my routine. My hair feels especially silky smooth after application, and lasted for another day. Overall my split ends have improved and for this price I think it's worth it!One of the best products for hair strength on the market
Great for strengthening ends and helping brittle hair, particular highlighted and fine like mine. I use this in place of my conditioner.Really like but dont love
I have loved kerastase shampoo so i tried this mask out. I do think it made a difference in the health of my hair except It was as drastic of a difference which I expected and wanted.amazing!
My hair loves me for purchasing this produceLove the results
My hair has been really damaged, dry and easily knotted lately. I have a go-to hair mask I normally use, but it has been reformulated. On the hunt for a new product, I chose this one. It has really helped with adding softness and shine to my hair. Love the results!Return of bounce and shine
I have been blow drying my coloured and highlighted hair more often lately. Add winter heating and my hair was feeling very dry, stiff and unmanageable. I bought the Extentoniste Mask to repair the heat damage. It restored my hair after the first use. It smells nice and works quickly. I have mid length fine straight hair.3rd Repurchase
3rd repurchase- leaves hair so soft and healthy! Definitely noticed more length tooHave been using for a decade
I am a huge kerastase fan. This is a really great mask that I have been using a few times a week and my bleached hair is feeling much softer and stronger. It does not feel heavy at all but is super moisturizing and leaves my hair soft and strong . I love you kerastase!Keeps my hair soft
This is by far the best hair mask I have ever used. My hair feels so soft and it Snell's amazing too. I am using this once every W week to maintain my coloured hair, doesn't help much with my Color but it keeps my hair soft.Amazing
Amazing hair mask and makes my hair feel healthy again! Would repurchaseAMAZING PRODUCT - LOVE IT.
OMG - What an amazing product. I watched the video that Amelia Porter from Adorebeauty posted and I purchased all the products that she was showing and I followed her instructions and can I say WOW my hair feels soft, silky, shiny first go.Very soft after first use
I have been eyeing for this hair mask and finally got it a week ago. I put on the hair mask for 5 minutes after I washed my hair. Without conditioner, the result is my hair is soft and no tangled ends. It also smells really nice.High quality weekly Masque
I am impressed with the results the Kerastase Resistance Extentionise range have given my hair. I pair this masque with the matching shampoo and alternate it weekly with the conditioner from the same range. I have seen a big improvement to the mid lengths and ends of my hair with continuous use of this range which is fantastic as this is where the most damage has occured.Highly moisturizing, pleasant scent.
I received a generous sample of this and it's the best mask I've tried so far. It took my thick, wavy hair and made it sleek and bouncy, with less frizz and fly-aways. I couldn't believe how soft my hair felt after using this mask for 10 minutes. I will definitely buy the full sized product. It's expensive but luxurious and actually works. This mask works way better for me than the Coco & Eve ...Read MoreMy hair feel so soft after treatment
I have been using this product for about a month and I really like it. It leaves my hair feeling great and hydratase without feeling greasy. It is perfect for summer days when the sun is drying the hair so much, perfect choice.Ok mask
I got a deluxe sample from goodie bag. It’s nice and hydrating. But I still prefer to use hair oil.Changed my hair
Dramatically made my hair thicken and feel less damaged. After severe blonde damage, this has supported my hair getting back to healthy and nourished hair.Nice
Lovely mask! It's a bit expensive, but you don't need a lot of product. Makes my hair very smooth and soft.New Conditioner!
This is sold as a mask however I have been using this in place of my regular conditioner and leaving on for 3 - 6 minutes (if I have time) and I LOVE IT! my hair is so soft, I get so many more days out of my wash, makes it so much easier to manage - love it, after watching Millie's video!Quality not quite meeting the price tag
The texture is slightly more watery than other Kérastase masque treatment I used before and the result did not quite match what could be expected for the price. However it did leave my hair fairly smooth and the smell is amazing but I used much cheaper products giving the same results. For these reason, I will happily finish these treatment but I would probably not re purchase this product.

Kerastase is on the expensive side! however their products are worth it! and they all smell great too!Life saver !
This product is literally a life saver ! I use it twice a week and made a huge difference in my hairAverage quality with and expensive price tag.
Smell is amazing. But I've used better. I think that for the price, the quality isn't what it should be.So soft
I received a sample of this a long time ago and finally used it once I started bleaching my hair. Just purchased a full size as I felt this indulgent treatment made my bleached long hair come back to life. It made my hair feel so soft and my hairdresser commented on how strong and healthy my hair is now.
Must have!Amazing!!
This masque is literally a life saver. After having a new hairdresser over process my blonde foils resulting in lots of breakage, I feel this masque has worked wonders! I now use it as my conditioner. 3 months in and my hair is smoother, no more snapping, no frizz, and it’s growing, yay! You only need the smallest amount so although pricey, you get a lot out of it. Couldn’t recommend more to other...Read Morelove the soft hair
the product leaves my hair feeling and looking soft. good for tangly hairAmazing!
For sure on the pricey side, but this stuff is so worth it! I've been using it for a about a year now and my hair feels so much softer and stronger then it used to, plus I've noticed that I've needed fewer trims throughout the year because I have way less breakage then I used to. Definitely worth the splurge!Delicious
I purchased this product to help grow out my hair. It smells so great and leaves my hair feeling clean, shiny and moisturised. It is worth the price point. Will buy again.Blonde Hair Friend
This makes my highlighted, dry hair feel so amazing. It makes so much of a difference to the feel once you blow dry, it seems to be much healthier.Works Well
This product leaves my hair feeling really soft, shiny and light, and has a really nice fresh smell to it. And a little product goes a long way too.Love this, great for dry, bleached hair.
I received this as a sample and used it recently when I bleached my hair at home. It really helped with keeping my hair smooth & soft and I loved it so much I purchased the full size.
I use it once a week and it instantly makes my hair feel more hydrated and smooth. I feel like my hair is less brittle since using it.Makes my hair lovely and soft
Lovely smell and makes my curly hair very soft. You don't need much so it goes a long way. I use it twice per week on my coloured hair.My hair felt stronger after using this!
I have long hair that is coloured & spend a lot of money to keep in good condition. This product was a sample I received & will now make it a part of my treatment options as I really noticed a difference when dry off after using this.ten out of ten
I've used this twice and am in love. My hair feels thicker, shinier and healthier after only two uses, and looks much shinier. I left it on in the shower for about five minutes. I will definitely be leaving it on next time for longer as a couple of the reviews recommend. Doesn't weigh my fine hair down or make it oily. Also smells amazing.Amazing
I don’t buy hair masks anymore because they all seem to leave a deposit and weigh down my fine hair. This product was sent as a sample and I was pleasantly surprised with the result. My hair was extremely soft, weightless and manageable! Can’t wait to use it again.My favourite mask
I’ve bought this mask a couple of times since Kerastase released this range and absolutely love it. Recently I thought I’d change it up and try a Shu Umera mask again that I previously used but was disappointed after loving the results from Kerastase. I use the mask weekly and leave on for approx 20-30 minutes. I have long thick course hair and was experiencing a lot of hair loss due to stress. Bu...Read MoreLeaves hair incredibly soft
I bought this product after receiving a generous sized sample (75ml). My hair is dry and slightly damaged. Using this mask regularly has made my hair look so much healthier, softer and dare I say glossier.. I have thin and limp hair so it’s important to me that a product doesn’t weigh it down or make it look greasy, but this mask gives me the softest bounciest hair which in turn gives the illusion...Read MoreGood for seriously dry hair
I have super dry ends and given the fact I haven't been able to get to a salon because of Covid, I gave this a whirl. It is really good for what it is, it leaves my hair feeling soft and relatively shiny but obviously nothing will be an in salon treatment with a hot towel.Great treatment
Lovely treatment. It hydrates my hair, smells great and makes me damaged bleached hair feel nice (which is no easy feat)So luxurious
I love using this mask on my hair as it is dehydrated, broken and artificially blonde. I usually leave it on for a few hours before washing out, after using it a few times now I have noticed my hair is more hydrated and less frizzy when I blow dry it.Amazing
This product left my hair so silky and frizz-free. A little went such a long way. New favouritesmells amazing
i love the smell of this hair mask and it does make your hair feel super super soft after blow drying. i think all the products under this brand are amazing!Great smell
I’ve been using this mask for a while and fine that it’s to heavy to use as a conditioner instead I recommend if you have fine to medium hair like myself to use it only as a mask instead to avoid oily build up. However it does have a nice texture and gives dry brittle hair some moisture making my hair feel healthier.Super nourishing.
This mask is super nourishing. I have oily hair with very dry, damaged ends. I apply this the night before washing my hair and braid it to help it soak in and wash it out the next day. It leaves my hair soft and silky without oily residue. It's a must-have for damaged or dry hair. My hair is also pretty thin and flat and this somehow seems to make it bouncy and full.Nice nourishing mask
I really like this mask if you have dry and damaged hair, as it definitely nourishes the hair and smooths split or frazzled ends. It smells divine and the packaging is beautiful. It is very thick and heavy so I don't recommend using too often, or for those with finer hair. Less is more!Silky
This masque leaves my hair really silky, one of the better ones I've tried. It smells very nice too. Much less frizz and good with colour treated hair.Impressed
The conditioner smells delicious and is very moisturising (I use it in conjunction with the rest of the line). I feel as though I already have less breakage and my hair feels considerably better to touch. I still have as much natural fall out though, so I don’t believe it retains hair any better than normal. Also of note, my hair is normally wavy and has some frizz but when using the line it tends...Read MoreGreat hair mask
This hair mask is divine. I received a sample size of it with a recent adore beauty order and I found it gave my hair shine and fewer split ends, I had enough sample for 4 masks which I used once a week. Definitely see the benefits, expensive but worth the price.Question
I have not used my product yet. I’m disappointed there is no direction in English how to use the hair mask. I’ve no idea how to apply or how long to leave inI like!
I received this as a free sample product a few months ago, and with recent consistent use I feel my hair looks and feels a lot healthier! I'm definitely considering repurchasing when it's finished.The Best
I love this treatment. I use it once a week on my long hair. Every one has recently been telling me my hair has grown so much and is now so long... I think it’s because of this treatment, less breakage so longer hair. It smells divine and leaves me hair so silky without it feeling dull.Use this for super silky hair
I use this once a week as directed by my hairdresser or if my hair needs a nice boost. Makes my hair super silky, soft and calms the frizz down.Silky smooth hair
The way this makes my hair feel is so nice! The smell is also drool-worthy and I always feel like I have left the hairdressers when I use it. Definitely recommend.My hair never used to grow until I found this product!
I used to have serious problems trying to grow my hair, as it is so fine it breaks off before getting any serious length. With regular trims and this treatment once a week it is now past my waist! Can definitely see the improvement to my split ends, which is definitely helping me get long hairBeautiful
I received a very generous sample pot of this from Adore Beauty recently.
This masque is very nourishing but it’s consistency is silky rather than thick, and it rinses out easily.
Some masques leave my hair limp and heavy, but this one didn’t. I love the condition of my long (dyed) blonde hair after using it. I now want to try the whole range.Very concentrated and rich
Although I like this I much prefer to Densifique masque. In saying that, this is really rich moisturizing and gives hair shine and strength. My hair feels like silk. It can however weigh down fine hair, so I wouldn't recommend this for really fine hair UNLESS it is severely damaged. My hair is actually so healthy now from all the Kerastase products I don't need this anyway.Great hair mask
Having received a sample pot from adore beauty I was very excited to try this hair mask. Having never tried a premium mask before I was impressed.
Having damage from heat styling I find my hair is beautiful and soft and less frizzy post blow dry then normal. I would like to purchase the shampoo and conditioner in the same brand to find out how good they all work together.Amazing
Just like the entire Extentioniste range, this mask is amazing. Must have when trying to grow long and healthy hair.Resistance Extentioniste Masque
I expected this mask to leave my hair feeling soft, healthy and help with hair growth. Unfortunately I didn't experience amazing results like I have had with other masks.Beautiful results
Great mask that does not contain proteins.
I looooove all Kerastase products, but this just leaves your hair so sleek smooth and hydrated but not heavy. The ingredients look ordinary but results are phenomenal. I have gine hair. This is quite concentrated so you only need a little bit. I love the extensionare line. I have definitely noticed less shedding and my hair is t...Read MoreThe best Haircare!
I love Kerastase! It’s so luxurious on my hair. I had quite dry ends, using only drugstore shampoo and conditioner- well, this has fixed it up! My hair is more manageable, soft, silky and strong. I have long, dark coloured hair, and this just works perfectly. Kerastase always does what it says it will. The only downside is the price tag, but it’s the price you pay for beauty!Worth the money
A little goes a long way, just one tub of this product, used once a week as conditioner lasted me a whole year! I usually have very dry hair but after using this my hair is nice and moisturized without feeling weighed down, highly recommend!Worth the money

I received this as a gift and am impressed with the results! My hair is visibly smoother and feels soft and healthy. It smells lovely and washes out easily, leaving my hair easy to comb after washing. Only downside is the price so I probably wouldn't purchase again for that reason.Hair mask
I used this to try and revive my thin, lank colour treated hair but it just wasn't as impressive as it should have been for the price.
Nothing wrong with it, but I think it's comparable to some of the $5 masks I've used on the market.
Recently my hair has been colour treated and since then my hair feels very dry and fragile.
Recently my hair has been colour treated and since then my hair feels very dry and fragile. My hairdresser recommended me to use Kérastase Resistance Masque Extentioniste once a week.

Gosh damn my hair loved this mask! Balayage left me with frizzy ends & winter made it worse but a few applications of Kerastase Resistance Masque has left me with a silken, flippy ponytail. Highly recommended but I hope you can do a better job at not overusing than I do!Very HIghdrating
I use this and a few other Kerastase products on my hair and use this as a conditioner, makes my hair really soft and shiny but doesn't make it feel heavy or weighed down - very good for a bleach blondeMakes my hair so shiny
I love this masque. I use it as a regular conditioner and I've gotten so many compliments about how shiny my hair is when I use it. It closes the cuticle without weighing down my fine oily hair. Highly recommended!Love!
My fave hair masque! Love the smell, texture, soft/conditioning feeling after using and rinsing it out!
You don't need to use much to see the benefit, and so it is quite a cost-effective addition to your haircare routine.Amazing
This smells amazing and makes my hair so smooth. I have blonde hair and love the way it helps the dryness on my ends. Def recommend using this once a weekFood for Hair, Nourishing
I received this as a gift with purchase so have only applied it twice (all that the gift tub allowed) and oh my, both times my hair felt healthier and looked shinier. Will definitely be using again.Pleasantly surprised
I received this mask as a free sample with my Adore Beauty order. I was pleasantly surprised to try this as I use a "cheap & nasty" hair mask from Coles normally. I was delighted that this product was entirely better and I could definetly tell the difference. My hair has never felt smoother & shinier. I would definetly recommend however I will not purchase due to the price point unfortunately.Very good
This mask works wonders for dry damaged hair. It was recommended to me by a stylist and it’s been a staple in my hair care routine ever since. Highly recommend.Not worth the $$
I have thick, frizzy, curly and bleach damaged hair. I was recommended this product by a hair stylist but sadly, I was pretty disappointed. It left my hair feeling quite sticky/like I hadn't washed out the product properly even though I double rinsed. I tried using smaller amounts, but had the same problem. It may just not work on my hair but not sure it's really worth the price tag.Best treatment ever!
This is the best treatment ever! It smells great and leaves the hair silky smooth and easy to manage. It's definitely worth the price tag a little goes a long way! Highly recommended!!It's okay.....
It's good to have a hair mask that you can use it on the scalp, but it's just an okay product with expensive price...Long hair!
I received a deluxe sample of this and whilst I may not have had enough uses to tell if it helps hair growth (and I’ve also been using the JS Hair & Energy Vitamins which are amazing!!) my hair was left soft, shiny and not dry at all. It stayed like that til the next wash too. It is expensive and whilst not my HG hair mask, it’s a really lovely product.Super hydrating leaves your hair like silk
I received this as a gift and it left me hair like silk after use. I can see how with repeated use how it would help your hair grow longer faster as it is sooooo nourishing.Worked well
I really like this mask! It left my hair very soft, shiny and it smells amazing. The only down side is it is a bit pricey and didn’t last me very long. I would however buy it again because I felt like it did improve my damaged hair.Worked well

I tried this as a sample and my hair was more hydrated and felt smoother, but not good enough results for the price.Lovely hair mask
I received a sample of this recently. It seems really lovely and seems to add hydration and shine to my hair. I've only used it once so far but really enjoyed it. You only need a small amount so the full sized product would last for so many uses. Would recommend!Great
The Kerastase scent is so lovely and this mask really strengthened and repaired my hair (damaged by hot tools, but never been dyed)It does what it says
I have used this mask along with the shampoo and conditioner from this range with a distinct goal to encourage length in my hair after it was cut much shorter than I wanted. After about 7 months use I can attest that for me these products were a life saver.

Purchased this mask to have a switch up from the Olaplex mask and so far its been pretty good. I try to keep it away from my roots as i found it can be a little heavy (i have thick hair with fine ends). Im really exited to see the long term effects over the next few months of use.Love
Kerastase products are really beautiful. I love all of their hair masks they really seem to work. Makes my hair soft and silkyStronger, smoother, softer hair
I love this product! I have bleached blonde, dry hair that is in desperate need of some extra loving. I use this as an addition to my regular shampoo and conditioner.
I like to use it once a week, and I've noticed my hair has been much more tame and lest probe to breakage.
I would recommend for anyone who has hair in stress!The best treatment
I personally prefer the treatment instead of using conditioner just find it heavy and more concentrated. Hair feels so silky smooth and I have noticed a great amount of growth too.Hair mask CPR
After I have double cleansed my head I apply this to my mid length and ends and leave it I’m for 15 mins (over reccomended time) and my hair once it’s washed out feels so soft. And once it’s dry it feel like your hair just had a visit to the hair salon without the price tag.Great mask !
Really great mask that also smells fantastic. Leaves my hair luscious, shiny and bouncy.
Be sure to wash it out thoroughly when this is done you get the best results.
Would defiantly purchase again!
