Blue Color Boost

Meet the healthier way to keep warm brown hair glossy and fade-free. Blue Color Boost gently neutralizes unwelcome brassiness with a unique botanical complex that also shields color from external aggressors like UV rays. New Wash, spatula and color ring are not included with 1-Pack and 4-Pack Color Boost purchases. Color Boosts must be mixed with 8oz New Wash. Do not use any Color Boost by itself.
