UNIQUE FORMULA: Unlike other color depositing conditioners, Color Mask Coffee Hair Toning Treatment gives your hair strength and nourishment with the help of plant-based proteins and amino acids. The end result is healthy hair with a vibrant blaze of color. | FOR DARK BROWN AND BLACK HAIR: Color Mask Coffee Toning Treatment deposits deep coffee pigment to black, dark brown, or medium brown hair. Deepens brown to a deep cool coffee brown, and eliminates brassy warm red/orange tones from brown hair. Also ideal as a toner for maintaining cool dark brown hair dye color! The pigment is semi-permanent. | VEGAN: Color Masks are 100% vegan and sulfate free, for a non-drying effect. The plant-based proteins and amino acids strengthen your hair and give it a gorgeous shine. Your hair color stays glowingly vibrant and your hair healthy. | CRUELTY-FREE: The entire Four Reasons product line is cruelty-free, and never tested on animals. Our packaging is made with sustainable materials. | REFRESH HAIR COLOR AND ELIMINATE BRASSY TONES: Use instead of a regular conditioner whenever your hair color needs to be refreshed. Note that your hair’s porosity, condition and current shade affect the result’s evenness. DO NOT USE IN BLONDE HAIR! ONLY INTENDED FOR BROWN AND BLACK HAIR.
