The Matrix Brass Off Mask is an intense neutralizing mask designed for blonde, highlighted, or gray hair. Thanks to its "Custom Neutralization" technology, it effectively neutralizes unwanted brassy tones to revive cool, luminous highlights. Its rich formula deeply nourishes the hair fiber, while improving shine and softness. Apply to washed and towel-dried hair, leave on for 3 to 7 minutes depending on the desired intensity, then rinse. Use 1 to 2 times a week to maintain neutral tones and a luminous blonde without damaging your hair.
