As someone who hasn't used Kerastase products for many years, I was pleased to be offered the chance to trial the Blond Absolu Bain Ultra Violet range.
As someone who hasn't used Kerastase products for many years, I was pleased to be offered the chance to trial the Blond Absolu Bain Ultra Violet range. I have naturally blonde hair, but have foils every 4 months to add a little 'oomph' to my natural colour. I don't normally use a shampoo and conditioner range specifically for blonde hair on a regular basis - it is normally every 3rd or 4th wash. For this trial I used the products every wash and I believe that for my hair it was probably a little too much. Unlike other reviewers, I didn't find the shampoo foamed very well at all. Not that is really a criticism, more an observation, as I don't believe shampoos need to lather alot to get the desired clean hair result. The shampoo is a beautiful deep purple colour and the fragrance is pleasant and my hair felt very soft after using it. I followed the instructions and left it on for about 5 minutes and followed with the corresponding conditioner. I was happy with the softness of my hair, but I actually noticed my hair had a slight purple tinge to it even though I rinsed my hair thoroughly. I believe this range would be better suited to me once I resume my normal routine of only using purple based products every 3rd wash. I will continue to use them in this way in the hope that I get the desired result of less brassiness and more brightly toned hair.

I’ve used the brand before so was excited to try this new product. The shampoo was easy to use and foamed well to wash my hair thoroughly and made my hair feel really soft. I left on for about 10mins to help neutralise any brassy zones. When my hair had dried I definitely noticed my color was a lot brighter and yellow tones had been toned. This is definitely a fantastic product for platinum blonde...Read MoreI haven't experienced Kérastase products before and I was very very impressed.
I haven't experienced Kérastase products before and I was very very impressed. The Bain Ultra Violet shampoo is delicious to use!

Wow, the colour inside is very bright purple but the product itself, amazing. My hair is natural platinum with little highlights of blonde too and my hair is just above the shoulder.

I've tried other products to reduce the brassy tones but nothing has been as good as the Kerastase Blond Absolu Bain Ultra Violet. My hair felt so clean and fresh and the brassy tones were neutralised. My friends have also started using this to neutralised their brassy tones. Great work Kerastase on this new product.

The Kerastase Bain Ultra Violet shampoo exceeded my expectations, the feel of my hair afterwards and the tone was so much better than previously used tone correcting shampoos. The colour and scent was subtle but long lasting. Would certainly recommend for toning brassiness and have already convinced friends to use, based purely on my experience.Kérastase is a brand I love.
Kérastase is a brand I love. I was excited to see how this product worked, not having used ‘purple’ shampoos before. I have a streak of grey in the front and bleached foils/toner with golden highlights for remainder. My colour was due to get renewed so thought it wouldn’t harm to give this product a go. The purple cream lathered nicely and pefurme is divine. I shampooed as normal and dried with h...Read MoreAmazing! The shampoo left my hair feeling, smelling and looking great.
Amazing! The shampoo left my hair feeling, smelling and looking great. There was definitely a noticeable difference in my hair colour after even just the first use - brighter and less brassy. I was also impressed with how easily it washed out for a purple shampoo as usually I have trouble getting it all out Would recommend!I have always used a purple shampoo to maintain my blonde foils.
I have always used a purple shampoo to maintain my blonde foils. This is the first time I’ve really loved using one! The packaging is salon beautiful. The texture and smell of the shampoo is really appealing. It lathers well and doesn’t slide off my fine hair too fast, giving good coverage. It rinsing out nicely.

I have a mixture of grey hair and blonde tones from a previous dye job that is growing out. The regrowth was dull and the outgrowing colour had a seriously brassy tone to it that was quite unattractive. I had been considering having the old colour stripped out, I disliked it that much.

I haven’t used this brand before but have used other purple shampoos with no result. This shampoo along with the conditioner worked. I definitely noticed a difference on my first use toning down my colour to more ash tones. The shampoo lathers well and on rinsing out does not leave your hair feeling dry/ straw like as with other brands. My only negative would be that because you need to leave it i...Read MoreThe packaging is to die for.
The packaging is to die for. I started using Kerastase products over 30 years ago. Yes, they are a bit of a luxury item but they work! The shampoo smells divine and has that rich purple colour. It definitely neutralizes brassiness and your hair is so soft and swooshy afterwards.This is hands down the best violet shampoo I have tried.
This is hands down the best violet shampoo I have tried. It foams well and smells great. I kept it in for 5 minutes and the result was the same as using a toner,my hair came out fresh blind with no yellow hues. I will definitely buy this product again.I have greying dull and brittle hair.
I have greying dull and brittle hair. While I am not particularly worried about going grey I hate that my greys turn that horrid yellow brassy colour particularly in summer.

Beautiful smelling shampoo, very pleasant. I have used a few different brands of purple toning shampoo, but I didn't find this one to be as pigmented. It toned some of my blonde but not all of it - mind you I have about 4 different shades of blonde in my hair. It definitely works best on the lighter blondes. Hair feels soft afterwards, definitely not a drying shampoo. Probably wouldn't buy this a...Read MoreThis shampoo lathers up really well and definitely helps neutralise brassy hair.
This shampoo lathers up really well and definitely helps neutralise brassy hair. I would use this shampoo twice a week depending on the structure of your hair.

I was very fortunate to be selected to trial the Kérastase Blond Absolu range, including the Bain Ultra Violet.

Fabulous product. After my last visit to the hairstylists I was left with some brassy tones. I have been using another very popular toning shampoo which made no difference. This product removed all the brassiness in one shampoo. I have very dry, wavy hair and this product did not dry it out.I've used this product a couple of times and really enjoy it.
I've used this product a couple of times and really enjoy it. It has a lovely subtle fragrance, foams well and cleans the hair really well. I left it on for a few minutes just to try it out and I could see the difference after I dried it, the yellow I tend to get in my hair had gone.

I was lucky enough to get to trial this product range on my bleached platinum blonde and white/ grey hair. I'm not sure the trial was long enough to fully evaluate the products so I will continue to use them. So far, I am very happy with the results.

Couldn’t wait to try this shampoo. Lovely shaped bottle and easy open lid.

Can not get enough of the Kérastase Blond Absolu range! Oh my blonde haired goodness is this stuff legit! The shampoo smells like deep herbal royalty, thoroughly cleans without leaving my blonde curls feeling like straw and has yet to turn my hair purple (finally)! I love the shiny silver my curls get from this range, honestly, get it!I have thick, long, foiled blonde hair, and I am always aiming for a creamy blonde (I don’t like seeing any signs of brassiness).
I have thick, long, foiled blonde hair, and I am always aiming for a creamy blonde (I don’t like seeing any signs of brassiness). This shampoo is a very pigmented purple shampoo that lathers well and smells like a bouquet of flowers. Due to the intense purple colour, I would only use this once every second or third wash. I would gladly repurachase and recommend it, as it was effective as a toning ...Read MoreThis shampoo is a knock out!
This shampoo is a knock out! I love the way my hair feels after using, it remains oil-free and, less brassy and extra blonde for days after use. It is absolutely worth leaving this in for the whole 5 minutes as the results speak for themselves! I will definitely purchase again!I've used a lot of Kerastase products before.
I've used a lot of Kerastase products before. I used the shampoo during my holiday in Hawaii. My hair had a yellow tinge from the sun and the water. The shampoo is easy to use and for my short hair I only needed a small amount. I left it in for 10 minutes and the yellow tinge was gone and my hair was a lot brighter. I will keep using the the shampoo as it is great for my platinum blond hair.I was very impressed with this product far superior to others I have tried in the past
I was very impressed with this product far superior to others I have tried in the past, it lathered up well and left my hair looking much brighter love the color, I left it on for 5 minutes and the result was beautiful on my platinum blonde hair. I will definitely buy in the future .Highly recommend this shampoo for those with blonde highlights/foils!
Highly recommend this shampoo for those with blonde highlights/foils! I have had so many comments about how bright and blonde my hair looks since using this shampoo. I would almost consider this 'salon quality' in a bottle. The shampoo fragrance is delicious! After using this shampoo just once, my hair instantly feels silky and soft. Even after a blowdry, my hair hasn't felt dry and straw-like lik...Read MoreCool blonde
Amazing shampoo that will tone away brassiness. Leave hair feeling strong and moisturised. Don’t use every wash as it can overtone.Best purple shampoo
If you have recently made highlights your hair you can forget about going to the salon to pass toning once a month as this shampoo perfectly tones the hair with yellowish.
I loved it, until today was the shampoo that most toned the yellowish tones of my hair.Best purple shampoo
Amazing. Worth every penny. I have dark hair and I went very blonde and my hair loves to pull brassy this saves me so many trips to the salon. It is very strong so you do have to be careful how long you leave it on or it will tint your hair but the purple hue does fade with washing. Some may say it is expensive for a shampoo, but honestly, if you want to have nice healthy looking hair and have a s...Read MoreBest blonde shampoo I've used
Love the way it foams, really cleans my hair & leaves the blonde looking ashy, no more brass :)Amazing!!
My hair looks like I just left the salon! It’s my new fav blonde shampoo!! This works absolutely amazing!!! I will definitely be buying more once I’m out.Best of the best
Love this for eliminating brassy tones and keeping my blonde fresh, ashy and cool. Compared to a lot of similar products, this one does a great job for its inexpensive price!Love
I was always sneaky and used blonde shampoos against my hairdresser's recommendation - I just wanted that cool blonde, y'know - but they always built up in my hair over time and caused it to break at the (already fragile AF from all the bleach..) ends. Apparently this one also contains lovely cleansing and hydrating thingies, so it has my fussy hairdresser's tick of approval. I may well use this f...Read MoreGreat for Highlighted Hair
Purchased this along with the purple mask as my highlighted hair was damaged & turning orange. This is a great product to counteract the bronze as I’m gradually going lighter (my hair was dark brown with greys).Highly recommended!
My hairstylist recommended this and it hasn't disappointed!
I only wash my hair once a week anyway, so I have only been using this every 2nd week. I really can see that it's really helped extend the life of my colour and is really helping keep the brassiness at bay,
Okay - not amazing
I use a lot of kerastase products and have been for a while. I had high hopes for this product but was a bit let down. It worked okay but didn’t provide the cooler, whiter tones I wanted, it’s okay aaa shampoo but didn’t quite do the job for me and keeping my Brassy tones away.Keeps highlights cool
Love this product! Keeps my dyed blonde hair (natural brunette) cool and smoother, a salon finish! Would recommendBest Blonde shampoo I've found to date
I use a lot of Kerastase products, so was super keen to try the Blonde range when it came out. I have highlighted ash blonde hair which gets brassy very easily. This is probably the best purple shampoo I've ever used, primarily because it doesn't dry out my hair (as every other product I've tried does). It smells great (marine like scent). I don't use this every time I wash my hair as I like to mi...Read MoreKeeps my colour cool
The smell is divine, as with all their products. It’s a beautiful purple shampoo however it’s still a little drying to use every wash.Serious life saver!
My hair colour is my own natural light brown with a full head of blonde foils.
For such a long time it was snapping when wet and I was having major problems with it being knotty after I washed it no matter what products I used.
This is my number one fav!! Seriously, it has made my hair so good again! I’m so glad I bought itI love this product
I have bought this from my hair salon and I love it so much so I now bought it for the second time from adobeNo conditioner needed!
I absolutely love this shampoo. The bottle has lasted me for two months. I am washing my hair less frequently and I will definitely be repurchasing when I run out. Helps keep the brassy tones away. Leaves your hair colour looking bright and fresh. For the first time ever I used shampoo on its own and found that it was nourishing enough that my hair felt amazing even without conditioner.

I purchased this product as I absolutely LOVE other Kerastase products and have had such fabulous success with my hair over the last 7 months. I wanted to love this product as much as the others but in truth I can’t. I haven’t been using it for as last long but the thinner consistency of the shampoo is a really big downside for me. With the price tag in mind I find that due to the more liquid cons...Read MoreI use this weekly
I use this weekly to balance out any brassiness as I have dyed blonde hair. I shampoo it in leave it for about 5 minutes then wash out. It’s a perfect weekly treat.
I love the whole blonde rangeblond-tastic
Absolutely love this product, by far my favourite Kerastase shampoo. Since using this I have been able to leave more time between hair appointments as i've kept my colour much longer. It smells divine, leaves your hair silky soft and in great condition. 100% recommend for colour treated blondes.I love it
Lovely and hydrating for my hair, keeps out all brassy tones and leaves me with my perfect blonde.Amazing!
Cancels out yellows and isnt as dehydrating as other brandsGreat product!
I love everything by this brand! So good at cancelling out yellow and leaves my hair feeling amazing!Really works!
I have naturally medium brown hair that I have been dying ash blonde for the past 20 years. I have used a few highly rated blonde shampoos over the years, but none are better than this and I've only used it three times! The colour of my hair was a little on the yellow side before using it, but now all I can see is beautiful ashy tones.
I have thin hair and like products that nourish ...Read MoreFantastic shampoo
I use this shampoo along with the other products in the Kerastase Blond Absolu range and it keeps my bleached hair in tip top condition and perfect color. Does not leave an overly purple tone on the hair. I use it once a week and it lasts a lonf time which makes it worth the cost.Great for blonde highlights and grey hair
Love this shampoo it leaves my hair hydrated and reduces the brassiness tone.
Dont need much, lathers really well.So so in performance
I brought this based on the reviews however I found this to pretty much do nothing for my blonde hair. For me, it sits in the just OK category and I will be searching for another product to try rather than repurchase.Beautiful toning shampoo
Loving the Kerastase Ultra Violet Blond Bain! I have had blonde hair forever and have tried many different toning shampoos and conditioners over the years, and this one is my favorite.
Very concentrated so you only use the smallest amount, and not drying like many other toning shampoos. I follow up with the conditioner/mask which is also amazing. I am planning to purchase the other shampoo i...Read MorePerfect blonde
This shampoo rids every bit of brassy colours from blonde hair and creates the perfect buttery blonde.Nice
I do like this shampoo. Only downside is the price tag. Its a nice toning shampoo and leaves a nice reflective color. A must with the Blond Absolu conditioner.Excellent
Love this shampoo as it tones beautifully giving a stunning cool blonde. Used it with the masque to achieve a beautifully neutralised tone. Not as hydrating as the nutritive range and I did have to use some of the leave in from that range to help soften my hair. On the whole though it’s excellent and I’ll continue to buy and use.good product
I highly recommend this product. I have brown hair but is bleached blonde and this shampoo works wonders in getting rid of any brassiness. makes my hair so softWorth the money
I was hesitant to buy this shampoo based on the price, but my hair has never looked better. It keeps my hair bright and also really hydrated! It’s a MUST have for blondes!A new favourite
I highly recommend this product. I'm brunette but have blonde balayage and this shampoo works wonders in eradicating any brassiness. I have never found blonde shampoo to be effective but this is the exception. I use this product with Kerastate purple masque once per week and I honestly look like I've just walked out of the salon. Not only does it counteract any orange/gold tones, it smells incredi...Read MoreActually works, doesn’t stain hands !!

I think this is good but it’s really pricey for what it is. I can’t justify spending that much on shampoo when I go through it so quickly. It’s good but not for the price!Amazing shampoo
I love this shampoo. For the first time ever I'm getting compliments about my hair colour (even though it's a supermarket dye). I wanted to take a star off for the exorbitant price but couldn't bring myself to. :-) I just have to use tiny amounts and not as often as I'd like.Super nourishing
After just one wash I can tell the difference when it comes to this product. Works wonders with my tired, damaged and frizzy hair and well and truly eradicates any brassy tones. One of the best I've tried.Strong, nourishing purple shampoo
Love love love!
I’m a balayage blonde (level 10/11 at ends, blending into a 6 at roots) and I have tried everything from fanola, to American brands and everything on the Australian market. Everything ‘purple’ and toning seems to dry my fried hair out. This shampoo does not, and is the perfect balance of toning and care.

Shampoo feels and smells incredible. Didn’t turn my hands instantly purple like other blonde shampoos and My hair felt silky smooth when most blonde shampoos dry it out.
Smells amazing, tones well
I have highlighted blond hair with natural grey/white as well. Bought this to keep my colour toned and I love it. It smells amazing, a little goes a long way (I have unusually thick hair), and it achieves the toned look I am after. I will definitely be buying this again--it is a splurge but you do get your money's worth.Soft hair and maintains colour
I have my ends lightened and live in an area where we have to soften water which is a nightmare for coloured hair! My main issues are frizz and dryness and after the initial wash my hair was feeling quite silky and the lightness of my blonde was rejuvenated which is great considering it's my first Kerastase purchase.

I found this shampoo to be very effective and only need to use it once a week.

Good product
I brought this for a friend and she said that she really likes it! She has bleached hair and found this really brightening and good quality. It is expensive so I probably wouldn't purchase it for myself but I don't have blond hair! Good review overall thoughMy go-to option

It's hard to find a strong blonde shampoo that is hydrating but Kerastase has created it and it smells amazing!
