My favourite toning mask!
I love how soft and silky my hair feels without its volume being weighed down after this mask! Does an excellent job of toning my blonde as well.

Not Satisfied
I used the entire first jar and was never that happy with the results. It made my white hair too bright and the yellow ends a negligible difference. I found Aluram purple shampoo and it is amazing!

I used the Amika Bust Your Brass Toning + Strength Repair Mask once a week for about a month, and honestly I have not seen any difference at all. The whole reason I bought this mask was because it claimed it would tone my hair and get rid of the brassiness while making my blonde look brighter. I really expected to notice at least some improvement after using it consistently, but instead it made my hair look dull, darker, and not soft at all. My hair honestly looked better before I started using it. Super disappointing for the price and definitely not what I expected based on the reviews and claims.

Essential for blondes
I bleach and tone my own hair and it’s the secret between a bad home job and something even and impressive. This is the perfect finishing touch to get rid of those uneven spots of colour and achieving an even blonde. It also makes your hair feel amazing with nice slip. I will never be blonde without this product.

Takes a few uses, but fights brassiness very well! Leaves my hair very soft and refreshes the blonde in my hair.

Not it!
After using this product both professionally and at home I saw that it did not really benefit my blonde hair that much. You’re better off buying actual toner. It left a waxy coat on my hair and made it feel much dryer

My hair is mostly brown with blonde peekaboo coloring in the front, and I use this mask once a week to keep the blonde looking fresh and I find it really helps. It smells good and it’s very moisturizing.
