K18 Damage Shield is designed for anyone dealing with heat styling, color treatment, or environmental damage to their hair. The conditioner uses K18's peptide technology to strengthen hair fibers and reduce breakage while keeping strands light and shiny, making it suitable for all hair types including bleached and chemically processed hair.
The K18 Damage Shield Protective Conditioner (250ml) is a salon-grade, peptide-powered rinse-off conditioner engineered to actively shield hair from heat styling, color processing, and environmental damage while restoring the hair fiber from within. Formulated with K18's proprietary K18PEPTIDE technology alongside Ceramide NP and Alteromonas Ferment Extract, it works below the surface to reconnect broken keratin chains, seal the cuticle, and rebuild the hair's natural lipid barrier.
Its featherlight texture glides effortlessly through all hair types, including color-treated, bleached, and chemically processed strands, delivering visibly softer, stronger, and shinier results with every wash. With no residue or buildup, this conditioner reduces breakage and split ends while providing up to 3 days of protective conditioning so your hair stays resilient and salon-fresh between washes.
