Preference's Superior Fade-Defying Color and Shine System creates a rich long-lasting color spectrum—now with an ultra-cool trilogy of blue, iris and silver reflects that work to help neutralize and prevent orange undertones from resurfacing. From root to tip, color is kept luminous and glacially chic. Luminous color shines from every strand and defies fade-out for up to 8 beautiful weeks. Plus, our color protective Care Supreme Conditioner formulated with Golden Camelina Oil, anti-oxidant Vitamin e and uv Filter helps keep first day color vibrancy and provides silky, resilient hair. Shade Guide 5c is a luminous, medium brown with ultra-cool reflects to help neutralize and prevent red and orange undertones from resurfacing. Shade Tips If you hesitate between two Preference shades, choose the lightest one. On more than 50% gray, your results will be slightly lighter-looking than the results shown. On natural red hair, your result will be a medium reddish brown. Not recommended on hair that is color-treated darker than a medium brown.
