Matrix SoBoost is our permanent hair colour that can be mixed with the SoColor and ColorSync Collections to create soft pastel tones or full strength to pre-lightened hair for bold, vivid effects.
Achieve special effects with our four intense chromatic shades or customise your colour needs with the addition of added control or intense reflects.
• Blue - Ideal for neutralising unwanted brassiness and warmth when lifting hair and for adding cool tones to dark hair.
• Red - Boosts intensity of red, red-violet and violet formulas when added to any shade.
