A colour-safe pH-protective shampoo that cleanses gently while preserving the results of K18 repair treatments between applications. The Moda Team Review The Damage Shield Shampoo exists for a specific reason: to protect the structural repair that K18PEPTIDE™ creates between washes. Most shampoos — including many professional formulas — alter the pH of the hair during cleansing in a way that can disrupt the environment the K18PEPTIDE™ needs to remain bonded effectively. The Damage Shield Shampoo maintains the correct pH range to preserve that bond while delivering a thorough, gentle cleanse. It is not a repair shampoo — there is no K18PEPTIDE™ in it. The shampoo’s job is not to repair; it is to create the conditions that protect repair between applications of the mask. Used as part of the K18 system alongside the conditioner and leave-in mask, it extends the effective life of each mask application. For clients who are not using K18 but want a gentle, colour-safe daily shampoo that produces minimal frizz and tangles, it also works on its own. The formula is sulfate-free and mild enough for daily use on colour-treated, chemically processed or sensitive hair. Key Active Ingredient(s) pH-balancing system: Maintains the optimal hair shaft pH that allows K18PEPTIDE™ to remain bonded between applications, preserving repair results wash after wash. Gentle surfactant blend: Cleanses without stripping, adding frizz or causing mechanical damage during the cleanse step. How To Use Apply to wet hair. Lather and rinse thoroughly. Follow with K18 Damage Shield Protective Conditioner. Apply K18 Leave-In Mask after rinsing conditioner.
