K-Pak Color Therapy Shampoo is a color-care cleanser from Joico's professional K-Pak line, built around two named technologies: a SmartRelease liposome system that continues releasing rosehip oil, arginine, and keratin onto hair after rinsing, and a Quadrabond Peptide Complex that combines keratin peptides, arginine, dual polymers, and African manketti oil to target areas of structural damage. It's formulated for color-treated hair, with extra emphasis on hair that's been lightened, double-processed, or otherwise chemically stressed.

The wash itself is a standard lather-rinse shampoo, meant to be followed with K-Pak Color Therapy Conditioner. Note: sources conflict on whether this formula is sulfate- and paraben-free — some marketing copy claims both, but the ingredient panel we verified lists Sodium Laureth Sulfate and Methylparaben, so we're not making either claim here.
