K18 Damage Shield Protective Conditioner

K18 Damage Shield Protective Conditioner is a lightweight, nourishing conditioner made for hair that needs daily upkeep rather than an intensive fix — the everyday partner to K18's flagship leave-in mask. It's built for anyone who wants softer, more manageable hair after every wash, and it applies as a concentrated gel that spreads easily from mid-lengths to ends. A little goes a long way: hair comes out of the rinse feeling smooth, detangled, and light, never coated or weighed down by silicones or waxes.

Use it after shampooing, ideally paired with K18 Damage Shield Shampoo, applying a small amount from mid-lengths to ends and rinsing thoroughly. The formula is engineered to fortify hair's exterior lipid barrier so it's more resilient day to day, while K18PEPTIDE™ helps replenish the protein hair loses during washing. A biotech-produced polysaccharide and a fortifying ceramide blend work together on the outside of the hair fiber, forming a protective, biomimetic layer designed to help shield hair from UV exposure, mechanical styling, and everyday environmental aggressors for several days between washes, while the pH-optimized formula also helps minimize cuticle swelling for smoother, shinier results.

Key Benefits

• Biotech-produced polysaccharide acts as a biomimetic shield that helps protect hair from pollution and environmental aggressors.
• Fortifying ceramide blend helps seal damage sites along the hair cuticle, smoothing the surface and guarding against further damage.
• K18PEPTIDE™ replenishes protein lost during washing to help keep hair feeling strong.
• pH-optimized formula minimizes cuticle swelling during washing for smoother, shinier hair.
• Silicone- and wax-free formula softens, smooths, and detangles without buildup over time.

Used daily, it's designed to keep hair feeling protected between K18 mask treatments.
