Matrix SoBoost 56g

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.
• Copper – Boost vibrancy in auburns, warm browns and golden blondes
when added to any shades.
• Yellow – Brightens shades without adding red.
