Versatile formula can be used as a leave-in or rinse-out treatment. Use as a daily or weekly conditioner. Flower Shield Complex and sunscreens protect color-treated hair. Contains abundant amounts of the essential amino acids for proper color attachment within the hair: Ceramide-2 and Tyrosine. Over-processing and damage depletes hair of these nutrients, causing uneven color results and fading. Trauma treatment replaces these essential ingredients, improving color results and longevity.
