Safeguard your hair's microbiome and protect its core integrity from the very first step of your routine with the K18 Damage Shield pH Protective Shampoo. Designed with an optimized, microbiome-friendly acidic pH, this gentle yet effective cleanser helps prevent the swelling of the hair cuticle during washing, the primary cause of frizz, color fade, and structural protein loss.

Powered by the signature K18PEPTIDE™, this nourishing daily shampoo cleanses away dirt, excess sebum, and heavy buildup while actively supporting scalp health and strengthening hair bonds, leaving your hair clean, smooth, and resilient.

Key Benefits & Features

  • Microbiome-Friendly & Optimized pH: Formulated at an ideal acidic pH to keep the cuticle closed during washing, locking in color vibrancy and preventing mechanical damage.

  • Gentle Yet Deep Cleansing: Effectively removes dirt, oils, and styling buildup without stripping natural moisture or disrupting the scalp's natural barrier.

  • K18Peptide™ Infused: Replenishes vital proteins and protects hair strength while you wash, minimizing daily wear-and-tear.

  • Color Fade Protection: Preserves salon color vibrancy by preventing pigment leaching and cuticle disruption caused by harsh, high-pH shampoos.

  • Optimized for Pre-Treatment: Creates the ideal clean canvas for subsequent K18 treatments (like the Leave-In Molecular Repair Mask) by clearing away heavy film-forming silicones.

  • Universal Compatibility: Gentle enough for daily use and safe for all hair types, textures, color-treated, and chemically processed hair.
