K18 Hair Damage Shield Protective Conditioner

The new K18 Hair conditioner has a nourishing formula developed to be hair’s first defense against daily damage, shielding and protecting against harmful environmental and styling factors. It is designed to be used on non-mask days after K18’s Damage Shield shampoo (previously called PEPTIDE PREP™ pH maintenance shampoo).


Featuring K18’s signature Peptide, the Damage Shield protective conditioner is clinically proven to provide conditioning protection against damage from UV rays, mechanical styling and environmental aggressors for up to three days.


Additional benefits include:

  • Defends against damage: Shields against UV rays, environmental aggressors and daily styling damage for three days.
  • Maintains hair health: Fortifies hair’s exterior lipid barriers to make more resilient, resistant to damage and replenishes protein lost during washing.  
  • Prevents color-fade while enhancing shine: pH-optimized formula minimizes excess cuticle  swelling during washing and protects against oxidative damage, which can accelerate color loss  and dull hair 
  • Softens, smooths, and detangles: without film-forming silicones or waxes that can build up  over time, weighing hair down 


Ingredients include:

  • Biotech-produced polysaccharide acts as a biomimetic shield to protect hair against pollution and environmental aggressors.
  • Fortifying Ceramide Blend seals cuticles to protect against further damage.
  • K18PEPTIDETM replenishes protein lost during washing, while the cuticle is still swollen, to fortify hair health and strength.
  • Vitamin E works against oxidative damage, which can fade color and cause breakage.
