The K18 Damage Shield Protective Conditioner in the 930ml professional size is a salon-grade, science-backed formula engineered to rebuild and protect hair from within. Powered by K18's patented biomimetic peptide technology, it works at the molecular level to reverse damage caused by chemical treatments, heat styling, and environmental stressors.
Each application deeply nourishes the hair's inner structure, restoring broken keratin chains and rebuilding polypeptide bonds to deliver measurably stronger, more resilient hair. A protective shield forms around every strand to prevent future breakage, lock in moisture, and restore natural elasticity. Hair is left noticeably smoother, softer, and healthier with every use.
Trusted by professional stylists worldwide, this large-format bottle is designed for consistent, high-performance conditioning in both salon and at-home routines. Suitable for all hair types including color-treated, chemically processed, and heat-styled hair.
