K18 - Damage Shield Protective Conditioner

K18
$36.00

Nourishing, protective conditioner helps shield hair from daily damage to maintain hair health and improve smoothness and shine. Engineered to weightlessly soften and detangle while K18PEPTIDE™ helps replenish hair during washing.

Key Benefits:
• Clinically proven to provide conditioning protection against damage from UV rays, mechanical styling, and environmental aggressors for up to three days
• Fortifies hair’s exterior lipid barriers to make hair more resilient and resistant to damage
• pH-optimized formula minimizes excess cuticle swelling during washing to help keep hair smooth and maximize its natural shine
• Softens, smooths, and detangles—no film-forming silicones or waxes that can build up over time and weigh hair down.

Key Ingredients:
• 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.

How to Use:
Apply a small amount of conditioner from mid-lengths to ends and build as needed. Rinse thoroughly.
