What it is: Introducing Joico Color Intensity Metallic Muse Collection, five new impossible-to-resist shades that perfectly mimic the muted luster of liquid metal. What it does: Reconstructs as you color with K-PAK?s exclusive Quadramine Complex for guaranteed healthier-looking hair after every color service. Ultra nourishing Kukui Nut Oil leaves hair gorgeously conditioned amps up shine. What else you need to know: For best results, use the Metallic Muse shades on hair prelightened to the palest yellow or Level 10. Because most of the Metallic Muse shades are smoky and muted, it?s important to lift hair beyond the orange-yellow/orange stage.
