Joico K-PAK Reconstructor

An intensive protein treatment that rebuilds severely damaged hair fibers from cuticle to cortex to restore strength and elasticity.

An iconic, professional-grade protein treatment designed to rebuild and revitalize severely damaged, weak, or chemically over-processed hair. Renowned as a multi-award-winning hair hero, its intensive rinse-out formula works at a deep structural level, targeting compromised cuticles and cortex layers weakened by thermal styling, bleaching, or environmental stressors. Powered by Joico's Quadramine Complex and SmartRelease liposome technology—a high-concentration blend of 19 essential amino acids, Keratin, Arginine, and Rosehip Oil—it rapidly adheres to damaged sites to replenish lost building blocks, double hair resistance to breakage, and restore natural elasticity, suppleness, and health in just 5 minutes.

Size: 150 ml / 5.1 oz

How to Use

2. Apply: Apply a generous amount to clean, damp hair, focusing on damaged areas, mid-lengths, and ends.
3. Distribute: Comb through with a wide-tooth comb to ensure the protein formula coats every strand.
4. Process: Leave the treatment on for at least 5 minutes to allow the amino acids to rebuild the hair structure.
