To easily intensify or neutralize haircolor, Matrix introduces SoBoost Color Additives. SoBoost can be added to most Matrix SoColor and Color Sync formulas for personalized, customized color and artistry.
The direct dyes come in blue (neutralizes brass), red (intensifi es reds and red-violets), copper (boosts vibrancy in auburns, warm browns and golden blondes) and yellow (brightens brunettes and softens reds). Can be mixed with clear formulas for pastel tones or applied undiluted to pre-lightened hair for vivid effects.
Additionally, Matrix has introduced LightInsider Lightening System; the ammonia-free level-lifting system conditions, provides up to six levels of lift and can be used on or off the scalp.
