K18 DAMAGE SHIELD pH Protective Shampoo

K18's everyday shampoo, designed for regular use on non-mask wash days. A pH-optimised formula that minimises excess cuticle swelling during washing — one of the underappreciated ways that shampooing itself contributes to frizz and damage. Prevents tangling and frizz, preserves colour, and enhances shine. K18PEPTIDE™ replenishes protein lost during washing. Like the detox shampoo, it uses alpha-olefin sulphonate (AOS) as its primary surfactant, placing it in cgm_modified territory for strict CGM followers. Microbiome-certified, allergy-tested. Pairs with the DAMAGE SHIELD conditioner as a complete daily system.
