PEPTIDE PREP™ pH Maintenance Shampoo

pH-optimized cleansing shampoo formulated with K18PEPTIDE™

A cleansing shampoo microdosed with the patented K18PEPTIDE™. Powerful yet non-stripping formula is designed with an optimized pH that is safe enough for everyday use.

How it works

Cleanses while smoothing the hair surface: Effective yet safe cleansers break down and remove dirt + oil for optimal nourishment and manageability.

Designed for daily use: pH-balanced formula doesn’t disrupt the hair fiber or scalp environment and is safe to use daily if needed.
