K18's Damage Shield pH Protective Conditioner is a daily treatment designed to protect hair from environmental aggressors, UV rays, and mechanical styling for up to three days. Its lightweight formula detangles without weighing hair down, smooths the cuticle, and preserves natural shine.

Enriched with K18PEPTIDE™, this conditioner helps replenish proteins lost during washing, thus strengthening the hair fiber. It also contains a biotechnological polysaccharide that acts as a biomimetic shield against pollution, and a blend of fortifying ceramides that seal damaged areas of the cuticle.

Its pH-optimized formula (3.8–4.2) minimizes cuticle swelling during washing, thus reducing frizz and preserving color. Free of silicones and film-forming waxes, it is suitable for all hair types, including fine, curly, or color-treated hair.
