PEPTIDE PREP™ pH maintenance shampoo

what it is

A cleansing shampoo with optimized pH level to cleanse frequently without disturbing hair and scalp’s optimal

pH levels. Perfect for use within the K18 molecular repair routine.

what it does

• Creates the ideal foundation for healthy hair: Protects pH balance to keep the cuticle closed during

washing and protect hair’s natural moisture levels.

• Cleanses smartly: Plant-derived surfactants gently breakdown and remove dirt and oil.

• Preps hair for treatment: Everything performs better on a clean hair base including chemical services,

treatments (like our K18 molecular repair), and styling products.

why it works

• Intentional formulation protects pH balance: Optimized product pH won’t disturb hair or scalp

environment to protect keratin integrity and maintain strength, without stripping away moisture.

• Cleans with less: Powered by an intentional list of only 17 ingredients, you can feel good about what’s in

it—and what’s not (no fillers!).

• Promotes hair happiness: less dirt and oil on hair means it is the right amount of clean, leaving a clear

path for our K18PEPTIDE™ molecular repair or anything else your hair wants to take on.

scent: Clean Citrus formulated without: Sulfates, parabens, phthalates, lilial, silicones, artificial colors, sodium
