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, leave-on-free rinse conditioner engineered with K18's proprietary peptide technology to actively shield hair from environmental stressors, heat styling, and color-fading damage, restoring the hair fiber from within to deliver visibly softer, stronger, and shinier strands with every wash. Its featherlight, luxurious texture glides effortlessly through all hair types, including color-treated, bleached, and chemically processed hair, without weighing strands down, while its advanced formula works to reduce breakage and split ends so your hair looks and feels salon-fresh, healthy, and resilient long after you step out of the shower.
