Preps and deep cleanses the hair without striping the hair colour

Hair happiness starts with the cleanest hair possible. With a clean base, hair colour can be applied more vibrantly. Keeping this principle in mind, K18 treatments perform more effectively, and styling products work better. The Peptide Prep category from K18 was engineered to create the cleanest canvas for a healthy hair base to make every K18 application a hair-health changing experience. K18Peptide™ works to reduce protein loss that can occur during
washing to keep hair feeling soft, strong, healthy and clean.
