K18 Professional Molecular Repair Hair Mist is an advanced, leave-in pre-treatment designed to strengthen hair and reverse damage before chemical, coloring, or styling services. Powered by the patented K18PEPTIDE™, this lightweight mist penetrates the hair cortex to reconnect broken polypeptide chains and disulfide bonds in just 4 minutes. With a pH level of 7.5-8.0, it shifts the cuticle to allow for deep, effective repair from the inside out. Ideal for professional salon use, it improves hair elasticity, protects against future damage, and ensures long-lasting, healthy results for all hair types.
