K18 Damage Shield pH Protective Conditioner - 250ml

The K18 Damage Shield pH Protective Conditioner is a nourishing, clinically proven conditioner engineered to shield hair from three types of daily damage — UV rays, mechanical styling, and environmental aggressors — for up to 3 days. Powered by the patented K18PEPTIDE™ alongside a biotech-produced polysaccharide and a fortifying ceramide blend, this conditioner works both inside and outside the hair strand to replenish lost protein, seal the cuticle, and build resilience against everyday damage. The pH-optimized formula (pH 3.8–4.2) minimizes excess cuticle swelling during washing to help reduce frizz, preserve color vibrancy, and maximize shine. Free from film-forming silicones and waxes that can build up and weigh hair down, it weightlessly softens, smooths, and detangles for hair that looks and feels healthy wash after wash. Ideal for use between K18 molecular repair mask days as part of the DAMAGE SHIELD maintenance routine.
