Description

Hydrating skincare serum, now for hair. New Blond Absolu 2% Pure Hyaluronic Acid Serum by Kérastase is a hydrating, repairing blonde hair and scalp serum. It’s the ultimate blonde repair serum for blondes, as it contains Hyaluronic Acid – with our highest concentration of Macro and Micro Hyaluronic Acid – to repair the surface damage of hair and moisturize both scalp and hair.

 

The lightweight texture of this clear gel serum preserves the scalp barrier, leaving only a feeling of comfort. Tested on freshly lightened hair, this Kérastase serum repairs damage in one use, for stronger blonde hair, that is replenished, plumper and intensely hydrated.

 

Just like with skincare, you can layer 2% Pure Hyaluronic Acid Serum with Blond Absolu Huile Cicaextreme hair oil, to seal in the hydration, for ultimate repair.

 

Repairs damages in one use*, for 95% stronger blonde hair**.

 

*Surface damage. Instrumental test after application of 2% Pure Hyaluronic Acid Serum

**Instrumental test after application of Bain Lumiere, Cicaflash and 2% Hyaluronic Acid Serum

How To Use

IN-SALON PROTOCOL

 

1 – BATHE

Start with the application of Bain Lumière (to hydrate hair fibers) or Bain Ultra-Violet (to neutralize brassiness). Apply directly on the scalp. Develop foam & perform the 3 gestures of the Kérastase Massage. Rinse and repeat.

Tip: Bain Lumière can be used in duo with Bain Ultra-Violet, as the first shampoo.

 

2 – TREAT

Based on your diagnosis, and depending on how much time the customer has, apply Fusio Dose or Cicaflash.

Mix the Blond Absolu Concentré + Cicablond Booster. Apply Fusio Dose on each strand on lengths and ends. Detangle, no leave-in time, rinse immediately.

OR

Take 2 pumps of Cicaflash and apply on lengths & ends with a brush. Massage, and twist. Leave it on for 3 minutes. Add water & emulsify. Rinse thoroughly.

 

3 – HYDRATE & PROTECT

Just like with skincare, you can layer 2% Pure Hyaluronic Acid Serum with Huile Cicaextreme or Cicaplasme, to seal in the hydration, for ultimate repair.

On towel-dried hair, hydrates scalp & fiber with 2% Pure Hyaluronic Acid Serum. Apply up to 7 pumps on scalp section by section, spread by massage. Apply up to 13 pumps on fiber, depending on hair lengths.

Protect hair up to 450°F with Cicaplasme or Huile CicaExtreme. Put a small amount of the product in your hand. Apply section by section throughout lengths. Don't rinse. Blow dry.

Love this product

[This review was collected as part of a promotion.] I use this serum on my scalp every time I wash my hair, so twice a week and I see an improvement on my scalp, is not as dry as it was before using this product.

Kerastase Pure Hyaluronic Acid Serum Adds Moisture

This product definitely added moisture to my fine, very dry, highlighted blonde hair but I prefer other Keratase serums like the Nutritive serum or the 8 hours overnight serum. I would purchase again if it is a part of a gift set but not on its own because the amount of the product even though it's full sized is very small so a bit expensive for what you get!

Difference maker

This has really helped bring my distressed, colored blonde hair back to life. Truth be told, I use less than the directions suggest as first step post wash-condition. Then I follow up with Cicaplasme to seal in the HLA. My hair feels so much healthier since I started using this product about a year ago.

Hair no better/no worse

[This review was collected as part of a promotion.] Not really noticing anything different since I started using this. I have fine hair and it doesn’t make it feel like straw like it did for other reviewers so that’s good. I just don’t think it really makes a difference.

Hair protector

I recently tried this serum along with the cicanuit serum and my hair is noticeably healthier, as confirmed by my stylist before I told her I tried them. I had read some reviews about this making hair feel strawlike, but I found that brushing it through my hair and then blow drying, that my hair is soft and feels stronger. This has become part of my normal hair routine - shampoo, conditioner, towel dry, genesis heat protecting spray, comb through, towel dry, hyaluronic acid serum, comb through, air/blow dry. Use the cicanuit serum at bed time if I plan to not wash my hair the following day.

Drying

[This review was collected as part of a promotion.] Since the other blonde hair oil was discontinued I decided to try this thinking it would be the same or better since it's triple the price. Nope! It's very watery and drying on my ends so I returned it.

Impressive product

I've been using this serum for about 3 weeks and cannot explain how strong my hair feels. I have wavy/curly hair that I hi-lite every 5 weeks. I don't typically blow dry my hair so most of my damage comes from the color process. My hair stylist recommended this to me to continue to retain moisture. I applied it the night after I had my hair done and it has been in the best condition in years!!

Drying and sticky

Why, oh why, did you discontinue the blonde hair oil? It is impossible to find a hair oil for blonde hair that doesn’t darken it or make blonde hair brassy. I do not like this product. It is not a replacement or a substitute for the blonde hair oil. It is drying and sticky. Every time I use this product my hair feels coarse like straw. This is the only Kérastase product I do not love.

I am almost done with my second bottle and am sold on this product. I have color processed hair, use my flat iron a lot and have really damaged my hair-this has brought it back to life. I use a little less vs recommendation and then do layer on the blonde absolu oil after the hyaluronic acid. I like this whole product line, truth be told.

HOLY GRAIL FOR BLONDES

This has quickly become a staple in my hair care routine!!! My damaged, bleached hair has been brought back to life by this serum!! While the price tag may cause some questioning, it is absolutely worth every penny!! Liquid gold! I did find that the suggested amount was a bit much for my hair length, and have been able to use about half the dose, and still see the amazing benefits. Love love love this stuff!!

Bada bop ba baaa I’m mclovin it

Holy grail for lightened hair. My hair drinks this serum like it’s dying of thirst and it makes a HUGE noticeable difference. I have bleached blonde hair and whenever I use this product, my hair looks and feels like virgin/original hair. It gives it so much life and softness, there’s no way I could ever skip this serum in my hair routine. The only downside about it is the packaging. It’s a struggle to get the product out of the pump and the serum itself is a runny texture so when ur trying to pump it into your hands/fingertips it almost feels like it’s spilling from between your fingers which makes it difficult to apply to your hair or scalp. Also, the size of the container is soo small, they need to really make more size options for products like this. But besides those two flaws, the actual product itself is freaking liquid GOLD. You won’t regret buying it.

Effective and calming on my scalp and not greasy. Really like how this product feels but only 3 out of 5 due to size and cost - if you follow the directions on the bottle to apply to scalp (5 to 7 doses, 1 dose=1pump), it may last only a couple weeks.

This product is incredible, giving me unmatched shine, light, reflectiveness to my highlighted curls. Hydrating, lightly conditioning, this product will immediately perk up dull highlighted strands. Your hair can look freshly highlighted. Whatever magic is in this bottle, I hope they never change the formula. One of my top 3 Keratase products!

Definitely not for me

I use the entire line of Blond Absolu and love it, it changed my hair after I went blonde so I thought adding this could only make things better when you have damage. Boy was I wrong, I have used it three times and each time when I’m drying my hair I can’t get it smooth with just a blowout which I could before this product. My hair looks and feels awful when I use this so I will be taking it out of my regimen. A very expensive disappointment.

I was so excited for this product and followed the instructions explicitly including following it up with the Blond Absolu - my hair is soft to the touch but dry in appearance as well as frizzy. Incredibly disappointed - especially at the cost.I hope someday someone comes up with a product for porous blond highlighted hair which actually works.

Not quite certain…

I’ve used Kerastase for more than 15 yrs and have loved EVERY product I’ve tried/used. I do have my favorite products though and the list is rather long bc I believe Kerastase is the best you can buy! Unfortunately, I’m not certain I can say the same for the Hyaluronic Acid. First, I’ve used a full bottle in a few weeks, granted I was trying to be a bit conservative in my use bc of the small bottle size. The directions call for 7+ pumps, which seems a lot for such a small bottle…didn’t last very long. I couldn’t see any differences in my hair after the first few uses, nor could I after finishing the bottle. I may not have used it long enough but can’t bring myself to purchase a 2nd bottle, w/it being so small (and pricey!) and lasting only a short time, w/out signs of improvement. Bc Kerastase products are always quality, I’d still recommend trying it for yourself…everyone is different after all. It may work wonders for you, just not for me.

Pricey with terrible results

This product has worsened the condition of my hair. My hair was dry. It made it even dried and hard to detangle. One star is too much for it

The best program for help with colored hair.

[This review was collected as part of a promotion.] I love my Keratasé. I suffered with my hair breakage, dry, and told me that I couldn't color my hair blond or Marilyn Monroe blond! {Till I found Kerastasé.} Kerastasé. The the shampoo, conditioner, Mask is so wonderful and the treatment. Thank you Julie Nicosia

Sérum au top

[Cet avis a été recueilli en réponse à une offre.] Sérum qui est intéressant à utiliser parce qu’il se met sur cheveux mouillés/humides. J’aime beaucoup l’odeur qui est subtil mais qui reproduit l’expérience de « comme chez le coiffeur ». Je trouve qu’il hydrate vraiment bien mes cheveux bouclés et le petit plus: le flacon qui est canon !

2% Pure Hyaluronic Acid Serum

Texture is liquid and not serum/oilish. A big amount is needed to spread all over the head. I didn't see any change with my hair after applying.

My Hair Has Never Looked Better(except in my 20’s)

I use this every night on my hair; I definitely shampoo in the morning because it’s a little stiff from the serum but when I blow dry my hair looks very full and healthy.

Really helps with damage and frizz

I just started using this as a first step on my hair, which is dry, curly, fine (but high density), and very dark but has highlights/balayage that are ash blonde near the ends. It reduces frizz, makes my hair softer and my curls more defined, and I really like that it’s one product that I can use on my lengths and my dry scalp. I have a lot of baby hairs right now (not sure if it’s breakage or new growth or a mix) and this helps with the fuzziness of those too. Although it’s pricier than the cicaplasme serum (which I also like) it’s more concentrated and I use less—sometimes I use both products if my hair is feeling particularly fried, then follow with a curl cream. I like that this is intense but also lightweight enough to layer other products over without weighing down my hair.

Not just for blonds! Amazing with dark hair!

I am Asian, and this is not just for blonds! I have a bob, and I bleach and then biolage highlight with shades of fucshia. My stylist recommended this, and it is amazing. My hair is fine (e.g. limp) and straight, but there is a slight frizz. This product has made my hair super soft and shiny. It has also added a tiny bit of bounce which I love. My stylist said to only use two pumps, and it's perfect for me. If you are reading this and not a blond, try it! It's amazing! P.S. I love Kerastase and have been using this brand for decades. I tried to love Chroma Absolu, but I cannot stand the fragrance which just lingers in the hair. Hence, I use Blond Absolu which works just as great even if you are not blond. Bleached & processed hair is just hair, not just limited to only blond hair.

Shiny, strong hair

[This review was collected as part of a promotion.] I have thin, straight hair and this definitely improved the strength of my hair. I like how the product isn't sticky and is easy to apply. My hair looks so healthy and shiny after using the serum.

Soft and shiny without being oily

[This review was collected as part of a promotion.] I highly recommend Kérastase Blond Absolu Hyaluronic Acid Hair Serum. I have really thick and curly hair and any oils or serums that I use tend to sit on top of my hair and not soak in. This product did and didn't make my hair feel greasy. I will definitely buy it when I run out.

My new favorite hair product?

It was definitely love at first use. And I didn’t even use it “properly”. I have very thin, super bleached (10 level lift) very curly (3c) hair and I dye it vibrant colors like neon pink, candy blue, apple green, etc. I also straighten it most of the time. So let’s say I have very demanding and specific needs when it comes to my hair. I wash my hair with Bain Chroma Respect and treat with Masque Cicaextreme. I didn’t apply the Serum on my hair BEFORE my Cicaplasme. What I did was: I blowdried my hair straight with Ciment Termique and then applied Cicaplasme to finish straightening my hair with the flat iron. After that I applied Huile Cicaextreme AND THEN I finished my hair with the 2% Hyaluronic Acid Serum. I was amazed at how fast it absorbed and instantly felt SO soft and SO healthy as I’ve probably never felt my hair before. All other products where already a part of my routine and it was good. But the Serum made my hair EXCELLENT. Also I noticed my hair lasted actually very straight for days. I’m extremely impressed, Kérastase you did it again. Been a fan for years, before Blond Absolu line even existed, this is the best product of the line so far. A MUST for hair with very extreme needs.

Not what's best for me

[This review was collected as part of a promotion.] I got this from Buzzagent for an honest review. For me, it was not a good product. It turned my hair hard, as if I put on a lot of hair spray. At the end of the day I and white dried specks as if I had put glue in my hair and was peeling it off. Now, I didn't not like it personally, but it might be good for you. Just take it as a grain of salt.

Great but pricey

[This review was collected as part of a promotion.] I have fine, thin hair and I am quite weary of products that have to be applied at the scalp as those usually weigh my hair down and make it greasy. This Kerastase product really surprised me, as it has the opposite effect - it gives my hair a little bit of "crunch" which helps it hold volume better. The reason for not giving this a perfect score is the price. The instructions say to use an absurd amount of product - 7 pumps for the scalp and 7 more for the length. I was my hair every 5-7 days and after a month I've used up almost half of the bottle. Given the cost this unfortunately will not be something I repurchase, even though I really like how it works on me. At that rate it's just not sustainable. I do wish this came in a larger bottle.

Amazing Magic Serum.

This product is awesome . I have long natural Curley hair which I blow out straight . It tends to get dry on the ends . I apply the serum after I wash and dry my hair and it is amazing . My hair shines and it helps with the frizz . I love this serum.

I was amazed after my first use of this product. I immediately noticed my hair had more body , shine , it was just different. Please keep in mind I use good products, so to notice a difference says something. After I one use I had my house cleaned. To my dismay I cannot find this product. I immediately ordered another. This ladies and gentlemen is great stuff. Highly recommend!!

It works!!

[This review was collected as part of a promotion.] I have very fine hair that's dry, breaks easy, & I've been torturing w/bleach for +20 yrs. I get my hair cut & have new split ends almost as soon as I leave the salon. Initially, I was a little afraid it would make my hair greasy, but it didn't. I only used 3-4 pumps of Blond Absolu 2% Hyaluronic Serum on my towel dried hair & styled as usual. Since I began using this serum, my hair looks/feels healthier, softer & shinier. It has more body, & I'm amazed to say, less split ends! Bottom line, I would definitely use this product again!!
