K18 Damage Shield Protective Shampoo is a balanced, everyday cleansing shampoo made to reduce the swelling of the hair's outer layer that normally happens during washing, one of the reasons hair frizzes and tangles after a wash. It's built for regular use rather than occasional deep cleansing, and is gentle enough for every wash while still cleansing effectively.The formula uses a blend of gentle sulfate-free cleansers rather than harsher sulfates, combined with K18PEPTIDE to help replenish protein that hair naturally loses while it's washed. By keeping the wash balanced, the shampoo limits water absorption into the hair's outer layer that can otherwise leave hair dull, tangled and frizzy once dry. Balanced formula reduces outer-layer swelling during the wash step, not just after Color-safe, suitable for color-processed hair Gentle enough for daily or frequent washing Contains K18PEPTIDE to help offset protein loss during cleansing It's the first step of a two-part routine, followed by the matching Damage Shield conditioner. Like other K18 formulas, it includes several fragrance components, including citrus peel oils, so check the ingredient list if you're sensitive to any of them.
