Joico K-PAK Color Intensity Semi-Permanent System gives you the power to create vivid, on-trend, insanely intense shades. 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.
