The Science

A synergistic blend of skincare actives and superfoods

Squalane

A must-have skincare active for hydration, squalane is a biomimetic, mimicking the scalp’s natural sebum to rehydrate the hair and condition coloured strands from the inside out.

Açai Extract

A superfood rich in polyphenols and omegas, açai fruit smooths the cuticle and enhances elasticity to fight the frizz lightening can cause, protecting blondes from brittle strands.

Moringa Oil

Rich in antioxidants and oleic acid, moringa oil strengthens blonde hair against the everyday stressors that cause colour fading and brassiness. Because blonde hair shouldn’t be fragile hair.

Argan Oil

Known as ‘liquid gold,’ argan oil is rich in linoleic acid and vitamin E, replenishing the fatty acids and moisture stripped by bleach and colour to make blonde hair softer, shinier, golden.

Wow Very Impressed

I am someone who is very picky when it comes to toners or toning shampoos. My roots are dyed to level 7 and my ends are level 9 and 10. My goal was to neutralize the brass on my roots (orange) and even out the yellow on the ends. This is the best toning shampoo I ever used. Fanola and Shimmer Lights are super drying, wouldn�t recommend. This product made my ends a nice icy/platinum blonde color. It didn�t neutralize my roots but it made them more vibrant and blended. Im shocked to have found a toning shampoo that makes hair more vibrant and brighter, all past products I used were either too green/blue or dull. This product isn�t perfect (it would be if it tones level 7 and is more hydrating) but I highly recommend it; after 1 use I�m glad to have bought it. Size of bottle is smaller than I thought too but anyways happy.

We truly appreciate your detailed feedback—so glad our Blue Shampoo delivered brighter, more vibrant results while keeping your blonde looking fresh and luminous

Best blue shampoo

Very drying! If you buy this buy the mask to go with it. It works really well on my hair and smells so good and little bit goes a long way you only have to use it like once every 3/4 washes

Thanks for your honest feedback—this formula is highly concentrated for maximum toning, so pairing it with a mask and using it every few washes is a great way to keep hair balanced and hydrated while still cutting brassiness.

Amazing!

I had a ton of brassiness in my hair after getting it highlighted and ordered this shampoo and it completely transformed my hair! I love the end result! The before and after was from one application about 2 minutes in the shower. Definitely a must buy if you have brassiness like I had.

Amazing results like that are exactly what makes this a go-to—impressive to see such a visible transformation from just one quick use.

Great to reduce brassy color on light brown

Worked great!! I have light brown hair and had highlights on the end that had turned brassy and an overall red tone to the ends. One five minute treatment and my hair is shiny and the highlights pop.

Impressive results—just one short treatment bringing back shine and making those highlights pop is exactly what you want to see.

THRILLED with these results! Bye bye carroty hair.

I rarely bother to write product reviews unless they really WOW me - and this product has done that. I recently painted highlights into my own level 7ish blonde hair and even though I used toner afterward, my roots still had some parts with a stubborn orangey-carroty hue. I've never used a blue shampoo before but came across this one and ordered right away based on positive reviews. I left it on for 5 minutes on my crown and roots, and 1-2 minutes on the lengths, which needed far less correction, I just wanted to make sure the entire look was cohesive. The results are PERFECT and all the orange tone is gone. I'm blown away by how well this worked! As other reviews have stated, it is a bit drying so just use a good conditioner or hair mask afterward and you'll be fine.

Good job

It really works! I have joico blue shampoo, matrix brass off and I like this one more. Don't dry my hair, Remove yellow and orange tones. My hair is about a seventh tone level, and it has yellow and red tones that I wanted to remove. After the first use, I saw good results. I use it about once every week and a half.

Before super brassy! 1 wash and not brassy!

Oh my goodness this is incredible. My hair was very dark brown three days ago. I went through the process of going back to my blonde that I like to have which is more of a platinum blonde. So of course along the way I looked like a super ginger! I mean really orange, so much so, it was embarrassing. I couldn�t go outside. Had to wear a hat, it was just ridiculous, but that�s the nature of the beast and the way it works going through all the levels. Once I got it down to just being brassy as you see in the photo, I purchased this, used it early in the morning because it arrived at 4am�. and here�s the before orange and after blonde! Simply incredible! I�m so happy I bought the conditioner as well! No damage to my hair! HIGHLY RECOMMENDED!!!

Decent shampoo for the price

I got tired of paying exorbitant prices for the namebrand blue Martha shampoo, so I got this one instead it�s a good shampoo overall. I like the scent, it�s not too Perfume-y, does a decent job with maintaining my blonde color, and it produces a nice sudsy foam. But it still isn�t as good as the more recognizable brands, Which score better on those three items. You get what you pay for. Then again. Since I use so much shampoo, this one works well enough for the price. Will probably buy again.

Cancel that brass !

I recently discovered if we want to cancel brassiness in our bleached/highlighted hair, we need to be using a blue shampoo instead of purple. Going in I didn�t have really high hopes. I am amazed at what this did though! It looks like I got a professional toning service at a salon! I applied it and left it on about 3 minutes. It is a little drying, so I followed with a hydrating mask. I will now be using this regularly!
