Joico Vero K-PAK Color Intensity Semi-Permanent Hair Color Joico Vero K-PAK Color Intensity Color System gives haircolor pros the power to create vivid, on-trend, insanely intense shades. This intermixable palette of semi-permanents includes the three new shades?Red, Yellow and Orange?plus supporting shades of Blue, Magenta, Purple, Green, along with a Clear Mixer, so that it's possible to create any hue, shade and nuance. Designed to delight the artist that lives within every salon pro, Color Intensity can be applied straight from the tube, or combined in endless combinations. Each hue can be used with or without the Clear Mixer, for a range of intensities from extreme to moderate to less intense. Ideally applied to pre-lightened hair, results from these highly-pigmentized semi-permanents can last up to 8 shampoos, depending on hair's condition and porosity. And like all Joico Vero K-PAK Color, Color Intensity reconstructs as it colors, thanks to Joico's exclusive Quadramine Complex. Hair emerges shiny, healthy and manageable.
