K18 introduces its newest product, Damage Shield Conditioner. The inception of this product stemmed from consumers requesting an option for days they were not using the K18 mask but still wanted to wash their hair. The conditioner provides protection against damage from UV rays, mechanical styling, and environmental aggressors for up to three days. These aggressors can cause breakage, frizz, and dull hair color.

Damage Shield’s light-weight formula contains no film-forming silicones or waxes to help maintain hair health and improve smoothness and shine. Its fortifying ceramide blend supports hair’s resilience and strength, while the K18PEPTIDE replenishes hair during washing. 

How it Works

  • Biotech-produced polysaccharide acts as a biomimetic shield to protect hair against pollution and environmental aggressors. Biotech and vegan-produced polysaccharide is inspired by microorganisms in French Polynesia, which create a natural shield to protect against the harsh environment. This biomimetic barrier weightlessly protects hair against pollution and environmental aggressors
  • Fortifying Ceramide Blend seals damage sites in the hair cuticle – smoothing and protecting hair from further damage.
  • Fortifying Ceramide Blend with unique, nanodispersion delivery system is drawn like a magnet to damage sites in the hair cuticle, sealing them to smooth, condition, and protect the hair from further damage.
  • K18PEPTIDE 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.

How to Use


  1. After shampooing with the pH maintenance shampoo, squeeze out excess water.
  2. Apply a small amount from mid-lengths to ends.
  3. Rinse thoroughly. For added conditioning, wait 1-3 minutes.


The Damage Shield protective conditioner can be used after the K18 mask for extra smoothness, softness, and detangling.

  1. Shampoo (detox or pH maintenance shampoo) and towel-dry thoroughly.
  2. Apply 1-3 pumps of K18 leave-in molecular repair hair mask.
  3. Wait four minutes. Do not rinse out.
  4. Apply a quarter-sized amount of Damage Shield protective conditioner from mid-lengths to ends.
  5. Rinse thoroughly.
  6. You do not need to re-apply the K18 mask.

The Damage Shield Protective Conditioner ($36) is available at Sephora. For more information, visit
