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 ...

Amazing product
I was given this by my hairdresser when I first went blonde and it did WONDERS! Takes all the red tones out of my hair and almost acts as a gloss too. A bonus is that it smells good! Highly recommend for bright blondies!

I have stubborn black hair and I've been doing blonde for about 2 years. Finally tried this and it worked like a charm! Got my hair to the lightest it's ever been
It works!

Took the brass/red right or of my chocolate undertones! Big difference after just one use, and left my locks soft but full of body.
yes, I would buy this again

Gets the brassiness out! Keeps your hair moisturized and the product smells great .
Unsure about results, but worked!
I used this mask for the first time, without the shampoo that's part of the product line. It definitely left my hair feeling smoother, and I noticed blonder highlights as a result. I left it on for 30 min as other reviewers suggested, and had a foil cap on too (the foil wasn't by choice, it was the only cap available at the ulta I went too). I did blow dry it after, vs before where it was washed/air dried the previous night. It honestly looks more red after I used it, but the blonde pops more now. It worked, but I'll have to see if I like the results long term. I used gloves, so I didn't noticed any staining and on areas of my skin where it came into contact with it washed off easily. Overall I'd definitely recommend, especially if you have treated/highlighted hair!.

- 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
