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 ...

Not one to leave reviews but…
I absolutely love how this product has ACTUALLY toned my hair. I have what you'd consider "bronde" hair and purple or blue shampoo alone doesn't seem to work for me. What I like about this mask is it's a mixture of both, so my hair neutralizes perfectly. I am taking 1 star off because I had to do a lot of trial and error with this product, but that's okay because I give my advice to you guys. The directions say to keep it on for 10 minutes... but I have to keep mine on for about 30-40 minutes to see results AND I recommend washing your hair with a detox shampoo first. The product doesn't work if your hair is dirty or have oil/dry shampoo buildup (learned that the hard way). You also have to really lather it on the ends and then I incubate the hair by putting a cap on for the 30-40 min duration. So happy I stuck through with this product even if it's a lot of work because I finally found the perfect mask that doesn't dry my hair out AND combines both blue and purple. Seriously my hair feels so soft.

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 trade off. I have a grown out balayage that was applied to virgin hair so my hair is not dry and over processed. I use this once out of the two times a week I wash my hair and alternate this with another matrix moisturizing shampoo/conditioner. I use the brass off shampoo/conditioner and then this mask all per the manufacturers instructions. I will continue using this product until it runs out but will not be repurchasing. One pro is my husband loves the scent.
Really effective, just wash hands after uae
Describe Yourself Wavy highlighted light brown hair
Once my 6-weeks between cuts is past and I'm not using No-poo blue shampoo (why tone my naturally light brown hair, this is a great brass toning treatment!
works for ash blonde hair
I have level 8 ash blonde hair that is fine and tangles easily. I have tried several purple shampoos and conditioners but this blue mask makes the biggest impact on my mission to fighting orange and yellow tones. I have well water that contains a large amount of iron. I use a water softener and maintain it religiously. However, orange tones will show up unless I use this mask. It leaves my fine hair feeling hydrated, silky smooth and knocked out the brass!
So pleasantly surprised!!
Definitely works! I have light brown hair with blonde balayage highlights, and the majority of my hair that's darker tends to get brassy, especially on the ends. I tried this in the shower and left it on for only about 5 minutes and it noticed SUCH a difference. I was afraid it would be too strong on the lightest blonde by the time the rest was toned, but I didn't have that issue. Also worked well in place of my conditioner. So excited to keep using this as needed!

- 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
