Think of it as skincare for your hair.
With its rich, ultraviolet cream texture, this Hyaluronic Acid hair mask deeply reconstructs hair. It also contains Edelweiss Flowers Extract, and the two ingredients act together to nourish and restore the fiber of grey, white, silver or bleached hair.

Your hair color is evenly bright, the tone is cool and natural shine is restored.

How to maintain blonde hair?


Kérastase discovered the 2 golden rules of bleached hair.

First, bleached hair needs to be hydrated, and that means depositing a layer of moisturising and nourishing actives on top of the fiber cuticle to avoid surface damage.

Second, bleached hair needs fiber healing, protection and neutralisation, to strengthen the fiber, prevent future breakage and neutralise unwanted brassiness.

Why is hyaluronic acid good for blonde hair?


Kérastase is using the golden standard of molecules for blonde hair hydration: HYALURONIC ACID.

Through our Hyaluronic Acid produced by French Biotechnology, we have created the Blond Absolu products with MACRO-[H.A], to perfectly stay on the hair surface, to provide long-lasting moisture and reinforcement.

Blond Absolu Signature Scent


Inspired by the modernity and freshness of new colognes, blond absolu wants to connect with a new generation of consumers through a clean but luxurious and aromatic fragrance. Blooming flowers and dazzling citrus notes as the top notes to reveal a lasting experience, full of youth and audacity.

    Rated 5 out of 5 by from Outstanding I used this k food the first time today, oh my it’s completely improved the colour and condition of my hair. I left it on for 5 minutes as my hair had gotten very brassy, it totally toned it down to a much cooler colour and it feels great, highly recommend and I’m so glad I took a chance on this product as it’s a considered purchase.

    Rated 5 out of 5 by from Amazing mask I used it as combo with a purple shampoo and it's amazing. Never see purple mask working soooo good on yellow hair. Definitely my number 1 mask.
    Date published: 2023-04-17
    Rated 5 out of 5 by from Amazing results on my yellow blonde! I had a tester of this treatment from my hairdresser and immediately ordered it. I was so unhappy with my yellow brassy blonde and ready to go dark again when she suggested a treatment mask once a fortnite (I only wash my hair twice a week). I left it on for 8 minutes and my hair is gorgeously soft and glossy and a perfect shade of cool light blonde again! No need to change my colour now I've found this!

    Rated 5 out of 5 by from Worth every penny I don't normally buy expensive hair products, but after a lockdown home bleaching disaster I purchased this. It had an immediate positive effect on the terrible condition of the hair, made it manageable and also toned down the brassiness. Totally converted now.
    Date published: 2021-04-09
    Rated 5 out of 5 by from Great for brightening and reducing brassy tones I bought this about 2 months ago and it has completely transformed my hair! I used to have quite brassy ends but now they are looking much cooler and glossier. I tend to leave it on for about 15 mins, instead of 10 as it makes quite a big difference. Would definitely recommend.

    Rated 3 out of 5 by from First try Switched from my usual nutritive and resistance range . It dies not have the punch kerastase smell I had hoped for . Didn’t feel as luxurious while I was applying and the texture was so thick I seemed to use quiet a bit . Not as conditioning as Expected . The couloir of my highlighted hair seem to brighten up though . However I was slightly disappointed so I will revert back to my normal ranges !
    Date published: 2021-01-09
    Rated 1 out of 5 by from Extreme colour warning!!! As with all hair masks, I left this on longer than the guide on box, it totally changed my hair colour from blonde to grey and a lilac. I understand I dint follow instruction but the result was so severe there should be a warning that the primary function is colouring your hair not conditioning it. My hairdresser had to put 2 colour correctors on my hair and still remnants of lilac remain.
    Date published: 2019-10-04
    Rated 4 out of 5 by from It works! This product actually works ! and removes brassiness from highlighted blond hair . BUT do use disposable gloves as required despite the video declaring "use disposable gloves when applying" and also states that on the box ,the girl in the video is using bare hands !!. I forgot to use the gloves on one occasion and my hands and arms became very itchy and I had a rash . So be careful if you have sensitive skin . the first time I tried it I left it on for longer than 10mins -more like 15 and I had to wash and wash it out over and over again to remove the product as my hair was looking grey ! I now do 8-10 mins only and its fine . I am pleased with this product .
