Works wonders
I have used this product two months straight and can tell the difference! My split ends have reduced and my hair is feeling stronger.Great
Love the smell and it has improved the condition of my hair significantlyAmazing for hair that needs TLC
I've washed with this stuff a few times now and it's completely changed my hair for the better. It's smoother and more manageable, but I'm also having less breakage and fall while brushing. It's the new and improved ciment range and if you're looking for hair growth, this is your potionGreat
I always use it twice and the first time it hardly foams, but on the second application the shampoo washes the hair very well. It smells yummy!Very effective
My partner find this shampoo helps in delaying hair fall on top of helping to strengthen the roots of his hair.Fresh hair
Don't love this scent but definitely a great range for leaving damaged hair feeling silkyVery good shampoo
Very good shampoo. I'm not sure about the growth properties but my hair feels healthy and strongWorks really well
This product has helped my husband in hair growth as he was balding at some stage. It slows down the balding process while keeping his hair healthy.Amazing product
this really helps my hair. it is so much longer and healthierLength superstar
It’s made my hair grow so fast!!! I love itWon’t look back
I’ve been using this brand for a while now after it being recommended for years by my hairdresser. After hitting 30 I wanted to make sure my skin and hair were looked after so I invested in some good quality products. My hair feels light, fresh and healthy. Love the natural shine I’m getting now, I see the difference after using this product in comparison to the cheap supermarket products. Highly...Read MoreVery nice
This product is so nice,smells amaizing,and make your hair flesh,it is really for a long hair,don't buy if u have short hairGreat Shampoo
Great shampoo for lengthening and strengthening hair. A little goes a long way.Effective
Bought this for my very thin and damaged hair, my condition has improved so much within the last 2 months.Go to shampoo
Leaves hair clean with a pleasant but subtle scent, seems to stay clean longer too. Hooked after trying the travel set, this is now my favourite shampoo!always in my shower
i had scalp pain my entire life, this product fixed it. amazing.So far so good
I switched to this from the genesis range and so far I am liking it. It is too early to tell whether it is working for length, but my hair feels healthy and strong. I do a double wash, which helps keep my hair fresher for longer.So silky
This shampoo leaves my hair silky and smooth every time, even before conditioning. Also smells so good.Love the smell
Not sure that it has helped with strengthening, but leaves hair feeling really fresh and soft. Smells amazing tooRepeat purchase
Love this shampoo for when I need more protein in my hair. Paired with the conditioner it will grow your hair so quickly!Didnt see results
I used it for over 1 month but did not see any major results so i dont know. Maybe if i use it longer it will work but for me it did not work. I have short hairGreat product
I was overall pretty happy with this one. I have heard a lot of hype about it, so I thought I'd test it out. I have quite fine, bleached blonde hair that swings more to the oily side and I found it to be a pretty decent shampoo.Long and strong...
The Kerastase Extentioniste collection is outstanding! I recently tried another product... why?!? back to Kerastase it is, the Extentioniste products leave my hair detangled, healthy, strong, smelling lovely and long! I've recommended to family and friends who are KetaConverts.Nice shampoo
Works well and smells really nice.No difference so far
I have been using this for a few weeks as my hair as thinned and and become soooo dull. So far not impressed considering I love so many Kerastase products, kind of disappointing but hoping to see resultsGood
Lovely shine and hydrationOverprice
Smells nice but I wouldn't repurchaseLike

strengthening, restorative shampooGreat
Best shampoo & conditioner comboI wouldn't repurchase
Eh.. This really didn't feel like anything special for me. It left my hair feeling heavy yet dry? Smells nice but I wouldn't repurchase.Ok
Smells nice but not worth the hypeBest shampoo & conditioner combo
I have tried so many salon quality shampoo and conditioners, and these just take the cake in making my hair feel and looking fab for a week at a time as I only wash my hair once a weekNot the best
I really wanted to love this shampoo as I love the conditioner and masque from this range, however this shampoo is just not it. It takes me a lot of shampoo to even create a mild lather, leaves my hair incredibly dry yet still very dirty and greasy.Lovely shine and hydration
This lathers nicely and rinses out properly. It gives beautiful shine and hydration and hair is soft and silky afterwards. My hair is not coloured or curly.Very nice
Smell is great and has been so good for my dry hairSmells nice but not worth the hype
It was nice and smelled nice but it did not do anything for my hair. It did make them soft but that was about it and it is a bit overpricedGood

My dry hair condition has improved after using this for 2 months.Good

I've got gifted as a gift from my boyfriend. Love the smell of it, and it has improve the condition of my dry and splitting ends.Good
The best shampoo for my curly dry hair!Not worth the hype
Takes two shampoos to create a lather which has never been a problem for me before! Doesn't seem to do anything good for my hair, but it does smell wonderful. Screw off lids are super inconvenient as well.Dull Non Growing Hair No worries!
This shampoo is absolutely amazing! First I purchased a bottle a while ago, which I ended up leaving in Tasmania from my holiday, mind you, it was only used 3 times. Anyways, this shampoo does wonders to my hair, and even better pairing it with the conditioner which is HIGHLY recommended to get the full effect. As people said the shampoo is abit dryer, yeah well, the conditioner is highdrating......Read MoreLOVE
A hairdresser on titkok suggested this brand and I tried it out and I am obsessed!! seriously is the only shampoo that makes a noticeable difference in my hair and actually feels clean. COUldnt recommend this product enoughIts just OK
I found this range is just ok with my hair. I have a natural very damaged, thin, soft hair ( without bleaching or dying), this shampoo makes my hair drier after washed but somehow i feel my hair much thicker and growth fast. However i might not re purchase it, still buy product from Kerastase but definitely try another range.Pretty good
I like this product, smells so good, leaves my hair feeling nice and clean, The only downside I will say is that it makes my hair a tiny bit dryAmazing
1 week in and already feeling such a differenceLove it
The best shampoo for my curly dry hair! Smells awesome too.Average
Just a very average shampoo. Was hoping it could improve my issue of split ends but it didn't. It is not too worth the money.So drying! Not for fine bleached hair
The smell is pleasant but I am not enjoying this product range. I have long, fine bleached hair and after using this shampoo, I’m unable to even run my fingers through my hair. It’s very drying with the SLS and since it’s not cruelty free and full of the “nasties”, it’s hard to understand why people rave about this brand. A lot of the ingredients are harsh on the hair, I think this may be better s...Read MoreNot sure
I was so excited to try this because of the hype as my hair is looking so dull and fragile lately, but this hasn’t given me the results I was hoping for. I can get the same results from a drugstore shampoo, and my hair is not strengthened if anything it feels dryer since using this. It’s too overpriced and nothing special! Sorrysmells amazing
This is an excellent product that smells amazing and effectively shampoos. However I'm not sure it's worth the high price tag as other cheaper shampoos are just as effective.Underwhelming
I know this is a holy-grail product for lots of people but it missed the mark for me. My hair is thin with oily roots and dry mid-lengths and ends. I was hoping this product would help strengthen my hair but if anything, it felt drier and harder to manage. On the plus side, it smells beautiful.not for oily hair
I have oiily hair and I found out this shampoo not a great choice for me, it smells alright.Great result when paired with the Extentioniste Conditioner.
I was pleased with the results I got from washing my hair with this Kerastase Shampoo. I paired it with the Extentioniste Bain Conditioner which is why I feel I got such brilliant results. I will continue using it for the improvement in my hair health.All of their products are amazing
I’ve tried pretty much every hair product there is and this brand is officially the best!Nice smelling shampoo
It smells and feels fancy, which is what I was after but I'm not sure whether I've noticed a massive difference in the health of my hair or scalp. I've been using it with the conditioner and it has lasted me a while but still not sure whether it's worth repurchasing.Worth splurging
Great product that delivers results. Worth adding to cartGreat for hair the breaks
Great high quality shampoo for hair that prone to breakage! Hair feels and smells great after use. I followed this up with the conditioner and maskNot for me
I have used this Shampoo together with same series conditioner. I was hoping to see the difference in my hair that had split ends and just didn’t want to grow long. Unfortunately I feel like it didn’t do much to my hair. It feels bit drying too so I discontinued using it. Lots of better options on the market.Best shampoo to protect and love your hair
I always buy more- I have coloured hair, between using colour enhancing conditioner or shampoos I use this, my hair is so much healthier, I have NO split ends, and I have had blue to pink to orange hairLovely shampoo
Great smell, great texture. It makes my hair feel very soft. Will have to use for a bit longer to see its repairing abilities.Great for my hair
I have been using this shampoo for more than a month with the conditioner and I really like it, it smells great and my hair is so soft and shinny afterwards. I will probably purchase it again.Amazing for dry hair
I am so impressed with this shampoo. I have long dry hair, and find that my hair usually feels a bit limp and dry after washing however I can shampoo ( without conditioner even!) and my hair feels so much softer and way less dry. I feel as though the thickness of my hair has improved greatly too!Shinny and strong hair
It’s my second bottle for the Shampoo and Conditioner, certainly not disappoint. Makes my hair soft but bouncy and I realised after the first bottle of using shampoo and conditioner I have less hair loss ( I could tell from my paddle brush ). Love the smell, little bit overpriced but wouldn’t stop me from buying it as it worked as what it say it would :)Helpful
I can definitely see an improvement for my dry and damaged hair. Great product.Love This Shampoo! Great for Damaged Hair!
This shampoo by Kerastase is incredible! My hair is quite dry and brittle from being bleached and heat-treated so I am always looking for products that can improve the quality and softness of my hair. My hairdresser recommended this product and I am so glad she did! My hair is so much healthier after using Kerastase and I won't use anything else! 5 Stars!best Shampoo
Kerastase is such a great brand ! this shampoo is great, really helps me to improve the quality of my hair, and you can notice the difference just after one use.Good but not Great!
Whilst Kerastase is a quality brand by far, I found this shampoo to be under-performing. Whilst the smell is amazing I found nearly every wash took at least 3 shampoo's to even produce a mild lather. Hair feels somewhat dry afterwards and never really clean. It just doesn't cut the mustard.My go to shampoo
I purchased this shampoo again after trying to Kerastase Extentioniste 123 pack. After trying a new hairdresser who over processed the foils in my hair, I was left with so much breakage and loss of length. This shampoo is so gentle on my hair, it doesn’t leave it feeling dry, and you only need the smallest amount. I now use regularly with the masque treatment in Extentioniste, and my hair has hone...Read MoreLove it
I am a huge fan of Kerastase products and this shampoo is no exception. It smells fantastic and really made my hair feel so soft and nourished. I have dry, curly long hair and really want something to help with breakage. I loved this paired with the conditioner and the serum.Disappointing
I have fine hair that usually is fast growing but for last 12months has slowed down. So I was excited to try this to see would it make a difference. It's made a difference alright but not a positive one. It made my scalp very itchy, my hair would get super greasy quickly and even started getting pimples on my scalp. Disappointing for the price and considering other reviews that gave the opposite e...Read MoreNice
Gives a nice deep clean, my hair gets oily super easily and I find this helps to get rid of it! Really nice.Didn’t work for me
Positives - smells amazing.
Negatives - I found it quite drying, and didn’t see any improvement in strength or texture.Great
Such a nice shampoo, works well makes my hair feel so clean without stripping got completely. Love the smell.Great Shampoo
My hair is dry and curly and this is the only shampoo that doesn't leave my hair feeling like straw before I use conditioner. This shampoo also leaves my scalp feeling really clean and fresh.believe the reviews
My bleached blonde hair is feels smooth and more alive after using this - and I've only used this for 3 washes so far. Wish I would have just purchased this sooner! It is pricey, but a little goes a long way and I only wash my hair 3 times a week.
Not overly perfumed either.
Excellent
Another excellent product. Not as thick as the next erosion level up but does leave hair feeling thicker and more nourished. Has definitely minimised breakage. Excellent product.Incredible scent!!
I have long, fine, curly hair so finding a shampoo which works for me has been a challenge. However, I was pleasantly surprised by this product!
First off the scent is incredible! Secondly, I found that just a small 10 cent sized blob was more than enough product, so the bottle has lasted me a long time and justified the more expensive price point. I did however find that in order to get a ...Read MoreGreat for strengthening weak/brittle hair
I love this product to help reduce breakage caused by heat styling and other environmental factors. I have dry brittle hair that is constantly breaking and I found that this product helped to reduce breakage significantly. I definitely recommend it.Will never use anything else!
I purchased the entire range as soon as it was released and have gone on to buy them all several times, which is big for me because I like to change things up and try different products. I LOVE THIS RANGE and it does everything it says.
I was suffering from some hair loss due to stress and after starting this shampoo and conditioner I noticed a Significant decline in the amount of hair that...Read MoreI keep coming back
I experienced noticeable growth while using this. I have been most recently using Shu Uemura products but am going back onto this and the accompanying conditioner, I think that says a lot.Great shampoo
I use this shampoo with the Extentioniste conditioner and it's great! It leaves my hair feeling so clean, shiny and smooth - and what I especially love, is that it doesn't leave my fine hair looking limp. It's too early to tell whether it's strengthening my hair but I definitely recommend this shampoo.shine shine shine
Lovely shampoo. I have fine hair that gets oily extremely fast in winter time and this has been nice to use. I can't say that I have seen any miracles in my hair but it definitely smells amazing and does give some great shine and bounce. I am very fussy when it comes to hair products as I have found that some can leave an oily residue or leave my hair limp, I did not have any issues with this part...Read Morepretty good
I have loved using this shampoo, I probably won't rebuy just because it isn't what my hair needs but it is a great shampoo and I would definitely recommend for people wanting to strengthen and grow out their hairNice shampoo
I can’t say that this made a dramatic difference to my hair growth but it is definitely a quality product that helped with the overall condition of my hair. I can never fault kerastase products!Very good
Really good shampoo. Using the conditioner as well, I am pleased to say I can see a difference in my short fine, getting thinner hair. It is definitely worth the money.Nice shampoo
This is a nice shampoo. Smells great and does it’s job but I’m just not sure this amount of $$ should be spent on a shampoo?meh
it is a nice shampoo but wouldn't say it did anything for length or longevity of hair beyond other high quality products.Great shampoo
I love this shampoo. I’ve been using this product for a while and find that All I need is about two 20 cent pieces of the shampoo to clean my now close to waist length hair. Like all the products in this rang it has a great smell and it doesn’t affect my hypersensitive scalp. Definitely recommend even for the price.Must try for Dandruff suffers
This shampoo is instantly cooling on the scalp and doesn't leave the scalp itchy after use. It's only been my first wash and it has *ALMOST* got rid of any flakeyness.Smells great - Salon Quality
I was recomended this Shampoo from my hairdresser. It's perfect for my hair type and it smells great.Healthy Hair
I purchased this product hoping it would help with hair growth and after using it for a month my hair is definitely looking and feeling a lot healthier, have not seen any growth as of yet but still hopeful as it has only been a monthReally great shampoo
Made my hair feel super healthy!Unbelievable how good this Shampoo is - Love it
I have very fine straight hair. My hair used to break all the time. This Shampoo has helped me so much. I started using it every day for a month and then to just twice weekly and it has helped my split ends, my hair is stronger and it feels amazing to touch. Highly recommend it.Impressed
The shampoo 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 to ...Read More
