Matrix Brass Off Duo is a color-depositing shampoo and conditioner set that uses blue-violet pigments to neutralize brassy, orange tones in lightened brunette and dark blonde hair, a Hair Care Set from Matrix's Total Results line.
The kit pairs a 10 oz Brass Off Blue Shampoo with a 10 oz Brass Off Blue Conditioner. Because blue-violet sits opposite orange on the color wheel, each wash deposits a small amount of toning pigment that counteracts the copper and orange undertones that tend to surface between salon color appointments on hair lightened from a darker base.
- Shampoo cleanses while depositing pigment; can be left on 2-5 minutes for stronger toning
- Conditioner follows to reinforce the tone and add slip and moisture
- Formulated for brunettes and dark blondes managing brass, not intended for very pale or white-blonde hair
Because the pigment is concentrated, wearing gloves during application helps avoid staining hands, and towels or shower surfaces can pick up color if rinsing is delayed. Extended contact time or use on very light or highly porous hair can leave a gray or ashy cast, so it works best every other wash rather than daily.
