Key Ingredient

Close-up of skincare ingredients: Edelweiss flower, hyaluronic acid, and antioxidants, layered in vibrant coloured gel.

Hyaluronic Acid

Hyaluronic Acid fills and heals fiber wounds from within for a uniform, deeply nourished cuticle. This ultra concentrated acid strengthens hair and hydrates scalp, preventing future breakage.


Edelweiss Flower

Rich in anti-oxidants to protect hair against daily damage and soften sensitised hair fibers.
Recovers & softens fiber; protects from damage by resisting to any environmental change.


Ultra Violet Neutralisers:​

Highly concentrated pigments that neutralise and remove brassy & yellow undertones. Illuminates reflects & highlights, and reveals radiant natural shine. ​

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 OMG!! Okay guys, I really wish I could show B&A’s so feel free to message me on Instagram, I’m no gatekeeper and would love for someone to feel as ecstatic as I did when I tried this shampoo!! This time last year I had black box-dyed hair (had been doing for over 2 years) if anyone knows their stuff, they’d know that no matter how much you bleach your hair, there will always be red undertones that you literally have to grow out. Anyway, after a trust the process kinda year, my hairdresser finally gave me the thumbs up to go light blonde balayage.. with in 2 weeks my undertones made a return and my hair was yellow and brassy :( I decided to use this shampoo and honestly the results after just ONE use are incredible!!! My hair is now a lovely light ash blonde and my balayage is really popping through nicely. As i have only used this once I am unsure how long it will last and what will happen the next time I use this but at this point in time I would give this product 6 stars if I could!! It is so noticeable, I think it’s better than a toner if that’s even possible! Honestly don’t mind if anyone wants to message me for B&A’s 🥰x

    Rated 1 out of 5 by from Awful I bought this shampoo a month ago after having my hair highlighted, it not only dried out my hair but changed the texture of it!! Waste of money and so harmful for hair!!! I made a big mistake to trust the brand’s reputation! The worst ever!

    Rated 5 out of 5 by from Best shampoo ever This is the best purple shampoo ever used. I received a sample to try , and from about a year i used it all the time. It's shades your yellow hair sooooo good and ladt for sooo long. It does get your hair a bit dry , but I use it with purple hair mask and it's perfect. Definitely my number 1 .

    Rated 1 out of 5 by from Itchy Head I bought this for myself as part of a Christmas gift set. Since using the products I’ve noticed that my head is very itchy. It must be one of the ingredients but I’m not sure which one. It’s a shame as I’ve used Kerastase products before and had no problems, and they are not a cheap products.

    Rated 1 out of 5 by from Wrecked my hair I tried this as my hair was a bit brassy after the last visit to the hairdresser. My hair emerged like straw even though I also used the conditioner. It also scoured my skin making it red, dry and flakey. I use other Kerastase products without experiencing such problems.

    Rated 5 out of 5 by from INSANE RESULTS This shampoo works in minutes and takes ALL the brassy tones out of my hair whilst caring for it! Highly recommend

    Rated 5 out of 5 by from Love this…. Love the shampoo, definitely takes the brassiness out of my hair and I also love the smell and feeling after. Feels like a great quality shampoo.
    Date published: 2022-09-13
    Rated 4 out of 5 by from Product quality okay The shampoo itself was fair to good for restoring blonde and banishing brassiness. I did however find it quite drying to my hair, particularly the ends. Also the bottle design wasn't great and the lid came off in my gym bag, the product went all over the contents of my bag stained my white trainers, which wasn't ideal. The bottle design would be better with a clip top, rather than a swivel top.
