Leave-in Molecular Repair Hair Mask

K18's Leave-in Molecular Repair Hair Mask targets weakened, chemically treated strands to restore resilience and smoothness. The lightweight, salon-style mask absorbs quickly without heaviness and suits those seeking repair rather than moisture-only care. Fragrance-free and designed for regular use, it works well for color-treated, heat-styled, or brittle hair in need of visible strengthening.
