Joico K-Pak Deep Penetrating Treatment is a powerful 5 minute intense reconstructor that rebuilds and strengthens weak, physically and/or over processed chemically treated hair. Lost or depleted Amino Acids are replenished with a high concentration of Quadramine Complex for maximum reconstruction and protection from the outside cuticle to the inside cortex. Fragile and damaged hair is restored to its original condition and strength, helping to prevent colour loss.
