Great
This product is amazing I have blonde hair and this neutralised my yellow. It also gave me clean blonde. My only concern is it's quite thick, therefore quite heavy, for my thin hair But being a mask it will be used once a week. Defiantly recommend for any lightened hair.

Works but drying
I have used this about 3-4 times now and while it does work with neutralizing the brassy tones in my hair, I have noticed that my hair is dryer and my nails have become dry, weak and brittle as well from application. My hair is not as shiny and healthy looking as it used to be, so it's definitely a ...

Doesn't work
Verified Buyer
I tried this as instructed and also on dry hair but it didn't work.
Keeps my blonde looking icyyyyy💙
I use this about every 4 days and leave it on for 13 minutes after I shampoo. It gets the yellow out and makes my hair look great! Yeah, it is messy but all you need to do is wash your hands really good after and make sure you're not slinging it around in the shower!

Blue is a Game Changer!!!
WOW. I am honestly so impressed by this product. I have been growing out blonde highlights for over a year, and letting my natural brown come in. But, over the summer I used Sun Bum lightening spray which made my hair kinda orange-y and brassy. I was using purple shampoo but it wasn't doing the trick. I found this hair mask and wow what a difference! I bet using it another time will reduce it even more! It darkened my hair a little too which is what I wanted to achieve. I will definitely keep buying this and would try the other Brass Off products too.

- Q
would this help neutralize red tones aswell as a brunette with red Ish orange undertones from box dye
- Asked by al
- Official Answer By Matrix - Brand EngageHi there! Thank you for reaching out about our Brass Off Custom Neutralization Hair Mask. That's a very common and understandable concern for brunettes who experience unwanted red-orange undertones from box dye! Our Brass Off Custom Neutralization Hair Mask is specifically formulated with blue-violet pigments. These pigments are highly effective at neutralizing unwanted orange and yellow brassy tones in brunette hair. While it excels at targeting orange and yellow, it is not primarily designed to neutralize strong red tones. For significant red undertones, a product with green pigments would be more effective. However, if your "reddish-orange" undertones lean more heavily towards the orange side, the Brass Off mask will certainly help to counteract those orange hues and bring a cooler tone to your brunette.Was this answer helpful to you
