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.

Très bon produit mes cheveux sont plus beaux

Merci beaucoup!

Love using this between washes to keep the brassiness away. Super quick and easy to use.

This spray has been great between salon visits. My color looks fresher and less orange.

Really helps with the orange tones in my hair. My blonde looks alot cooler after using it.

Good for quick touch ups

Really convenient when I notice some orange coming through between salon appointments. I just wish the toning was a little stronger on my darkest pieces.

Love the shine

My color looks fresher but what surprised me most is how shiny and silky my hair feels after. Doesn't weigh it down either.

Took me a few tries

I used too much the first time lol. Once I figured out how much my hair needs I really liked the result. Soft and noticeably less brassy.

Exactly what I needed

I have light brown hair with highlights and sometimes they get too warm. A few sprays of this makes the color look much more balanced.

New favorite product

Been using this for about 2 weeks and I reach for it all the time now. Lightweight, smells good and doesn't make my fine hair greasy.

Great for my balayage

My balayage gets orangey pretty fast, especially around the front. This helps tone those warmer pieces and gives my hair a nice shine.

Nice subtle toning

The toning is a little more subtle than the shampoo for me, but I actually like that for everyday use. Leaves my hair really smooth.

Perfect between washes

I don't always want to use blue shampoo so this is perfect. I use a few sprays when my color needs a little refresh and thats it!

Didn't expect much but wow

Honestly wasn't sure a spray would do much for brassiness but I was surprised. My blonde looks cooler and brighter without feeling coated.

So easy to use

I love that I can just spray this in when my highlights start looking a little warm. Makes them look fresher and my hair feels really soft too.

Fantastic product. Would highly recommend it.

Works really well and doesnt make my hair feel dry. My highlights look so much better after using it.

I noticed a difference right away on my brassy pieces. Doesnt leave my hair feeling heavy either.

Love the product
It does exactly as described

Thank you so much for taking the time to share your thoughts about our Blue Neutralizing Spray! We appreciate it a lot!

Smells so good and works great. Will buy again

Thank you for the kind words!

Best hairspray for silver hair, non yellowing

J'ai un cuir chevelu sensible à beaucoup de produits. Ce produit est parfait pour moi.

My hairdresser recommended this product and now that I tried it I couldn't try any other product. Amazing results for my blonde hair

Will it bring out my blonde highlights

Blacklight Blonde Science

If your highlights look a bit dull or brassy, this is exactly the kind of product that makes them stand out again. The Blue Neutralizing Spray will enhance your blonde highlights (neutralizes unwanted warm/orange tones, make your highlights look cooler and brighter and add shine and smoothness). However, it won't lighten or create new highlights. Hope this answers your question!
