K18 Peptide Prep PH Maintenance Shampoo 8.5 oz Set of 2
Key item features
- This shampoo features a pH-balanced formula that gently cleanses using plant-derived surfactants, ensuring your hair is free of dirt and oil without over-drying or disrupting its natural pH balance—making it perfectly safe for daily use.
- The optimized pH minimizes excess cuticle swelling during washing, which helps tame frizz, preserve vibrant color, and enhance shine—protecting hair integrity even under frequent cleansing.
- Designed to be gentle enough for everyday cleansing, this formula supports a balanced scalp microbiome and incorporates K18Peptide™, which helps reduce protein loss during washing and maintains hair strength.
- Beyond cleansing, the shampoo softens, smooths, and detangles hair using a “less-is-more” approach—free from buildup-causing silicones or waxes. It fortifies hair, reducing breakage, and protects against UV, environmental, and styling damage.
- Celebrated by Real Simple as an editor’s top pick for damaged and dry hair, this shampoo is highlighted for its bond-repairing technology, gentle cleansing, and ability to reduce breakage while leaving hair soft. It also ranked as the best overall in Byrdie’s test of shampoos for damaged hair.
