DAMAGE SHIELD™ Protective Conditioner is the daily partner to DAMAGE SHIELD™ pH Protective Shampoo. Together they help shield healthy hair from everyday damage. This lightweight formula combines the patented K18PEPTIDE™ with nourishing, skin-identical ingredients to condition, smooth, and protect without weighing hair down.

Protect: It helps defend hair from daily damage that causes dullness, frizz, breakage, and colour fade.
Nourish: Sweet almond oil, jojoba oil, and jojoba esters soften and add shine.
Strengthen the surface: Ceramide NP and phospholipids help reinforce the hair’s natural lipid barrier for smoother, more resilient strands.
Antioxidant care: Vitamin E (tocopherol) helps protect against environmental stressors.
Detangle and smooth: It leaves hair soft, manageable, and easy to comb through.

It’s colour-safe and gentle enough for every wash, and it’s suitable for all hair types and textures.

After shampooing with K18 DAMAGE SHIELD™ pH Protective Shampoo, gently squeeze out excess water.
Apply through mid-lengths and ends.
Comb or finger-detangle to distribute evenly.
Leave on for 1 to 2 minutes, then rinse thoroughly.
Using the K18 mask? Apply the conditioner after the mask, not before. Shampoo, towel-dry, apply K18 Leave-In Molecular Repair Hair Mask, wait 4 minutes, then condition and rinse.

All hair types and textures, including fine, thick, curly, coily, colour-treated, bleached, and damaged hair. It’s ideal for daily use and anyone wanting lightweight conditioning that protects colour and fights frizz.

Clinically proven to provide conditioning protection against damage from UV rays, mechanical styling, and environmental aggressors for up to 3 days*. Fortifies, softens, and detangles hair.

Defends against damage: Conditioning protection against damage from UV rays, environmental aggressors, and daily mechanical styling for up to 3 days.
Maintains hair health: Fortifies hair’s exterior lipid barriers to make hair more resilient and resistant to damage. K18PEPTIDE™ replenishes protein lost during washing.
Enhances hair’s natural shine: pH-optimized formula minimizes excess cuticle swelling during washing to help keep hair smooth and maximize shine.
Softens, smooths, and detangles: Without film-forming silicones or waxes that can build up over time and weigh hair down.
