Any type of coating whether it's product buildup, sebum/oil buildup, or even mineral + metal buildup from hard water can block our biomimetic peptide from getting where it needs to go. We recommend PEPTIDE PREP™ detox shampoo prior to K18 mask application for first-time users, or people that use a lot of styling products. This will clear the path for our peptide to fully penetrate hair, and deliver maximum molecular repair results.
