K18: SHIELD Your Healthiest Hair Against DAILY DAMAGE

K18's DAMAGE SHIELD category is developed to offer protection from damage between treatment mask days, and extra softening and detangling after salon services —this category includes the DAMAGE SHIELD pH protective shampoo and the protective conditioner.
WHAT IT IS
The colour-safe, pH-optimised shampoo with the patented K18PEPTIDE™ effectively cleanses while maintaining hair health. Scalp microbiome-friendly and gentle enough to use every time you cleanse, 91% said hair felt smoother, healthier, and not weighed down.
The nourishing, protective conditioner helps shield hair from daily damage to help maintain hair health and improve smoothness and shine. Engineered to weightlessly soften and detangle while the K18PEPTIDE™ helps replenish hair during washing.
WHY IT WORKS
pH PROTECTIVE SHAMPOO - Less is more formulation delivers a superior clean without compromise:
  • Optimized pH cleanses hair and scalp without over-drying
  • Certified microbiome-friendly formula removes dirt and oil without disrupting the scalp’s natural protective barrier
  • K18PEPTIDE™ helps reduce protein loss to keep hair feeling healthy and strong
  • Biotech-Produced Polysaccharide acts as a biomimetic shield to protect hair against pollution and environmental aggressors
  • Fortifying Ceramide Blend seals damage sites in the hair cuticle—smoothing and protecting hair from further damage
  • K18PEPTIDE™ replenishes protein lost during washing
DAMAGE SHIELD Protective Conditioner can be used for added smoothness, softness + detangling after the K18 Leave-in Molecular Repair Hair Mask. Alternatively, you can use it on the days where you want to skip your K18 Molecular repair hair mask.
