K18 Damage Shield Hair Strengthening & Protection Duo is an advanced hair care bundle specially designed to gently cleanse, strengthen, and protect hair against daily damage while improving softness, smoothness, and shine. This two-step hair care set combines K18 Damage Shield pH Protective Shampoo and Damage Shield Protective Conditioner for a complete cleansing and conditioning routine. Both formulas feature patented K18PEPTIDE™, a biomimetic peptide that helps replenish protein lost during washing and maintain stronger, healthier-looking hair. The pH-optimized shampoo contains plant-derived cleansing agents that effectively remove dirt, excess oil, and buildup without over-drying the scalp or disrupting its natural microbiome. Enriched with Panthenol and Glycerin, it supports moisture retention while minimizing cuticle swelling, frizz, and colour fading. The protective conditioner contains a biotech-produced polysaccharide that shields hair against environmental aggressors, while a Ceramide Blend strengthens the hair's protective outer layer and smooths damaged cuticles. Sweet Almond Oil, Jojoba Oil, and Vitamin E provide additional conditioning benefits, leaving hair soft, manageable, and shiny. Together, these colour-safe, silicone-free formulas offer lightweight nourishment and conditioning protection against UV exposure, mechanical styling, and environmental stressors for up to three days, making the duo suitable for regular use on all hair types, including damaged and colour-treated hair
