The K18 Damage Shield pH Protective Shampoo is a professional-grade cleanser formulated to maintain the hair's optimal pH balance while effectively removing dirt, oil, and buildup. Powered by patented K18PEPTIDE technology, this shampoo actively strengthens hair fibers and protects against future breakage. Its microbiome-friendly, sulfate-free formula makes it perfect for daily use on all hair types, especially those that are chemically treated, color-processed, or prone to heat damage. The optimized pH level keeps the hair cuticle sealed, resulting in smoother, shinier, and more resilient hair with every wash.
