KEY INGREDIENTS
Vitamins C+E Within the formula, Vitamin C & Vitamin E combine their power to brighten the fibre's cuticle and help maintain the integrity of the hair fibre.
Hyaluronic Acid Within this formula, two distinct molecular H.A. weights are used. In this formula, the low molecular weight H.A. penetrates the hair fibre, improving resistance, while the high molecular weight enhances smoothness and provides a plumping effect. When combined in the formula, this dual-action effect helps to deliver benefits both on the inside and outside of the hair fibre.

PDP Section FAQs
FREQUENTLY ASKED QUESTIONS
Why does lightened and bleached hair get brassy?
Bleaching and lightening the hair means removing the hair’s natural
pigments which can reveal unwanted undertones. When bleaching dark based hair colour, red or
orange undertones can appear. Even light-based hair colour can reveal unwanted undertones
when bleached. Blond Absolu Bain Ultra-Violet has Ultra-Violet Neutralisers in its formula
to cancel out unwanted undertones and get rid of brassiness.
How often should I use Blond Absolu Bain Ultra-Violet Purple
Shampoo?
Use Bain Ultra-Violet Purple Shampoo depending of your need of
neutralisation to get rid of brassiness and unwanted undertones. Complement by using Bain
Lumière on other wash days.
Can the Ultra-Violet Shampoo be used on natural blonde hair?
Yes, the Bain Ultra-Violet Shampoo can be used on both bleached or
colour treated and natural blond hair.

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

AwfulI 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!

Best shampoo everThis 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 .

Itchy HeadI 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.

Wrecked my hairI 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.

Product quality okayThe 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.
