K18 Peptide Prep pH Maintenance Shampoo

Gentle cleansing shampoo with optimal pH for everyday hair washing. Ideal for frequent washings or clients without a lot of product build-up and residue.

The PEPTIDE PREP™ category has been developed to create the purest foundation for your healthy hair, whether you are looking for an effective and gentle cleanse or a thorough detox. On a clean base, colour will be more vibrant, K18 treatments will be more effective and styling products will perform better. The formula is color-friendly and skincare inspired + with micro-dosed patented K18Peptide that nourishes hair while washing away product build-up.


  • Cleanses while cooling the hair surface
  • Effectively but safely removes dirt and grease while maintaining nourishment and manageability
  • pH-balanced formula does not disrupt the environment of the hair fiber or scalp and is safe to use daily if needed
  • Prepares hair for maximum results from treatment K18 Leave-In Molecular Repair Hair Mask
  • Contains only 17 ingredients (+ patented peptide), doesn't use unnecessary fillers or burdensome ingredients
  • pH 4.5 - 5.5 helps maintain color and does not dry hair
  • 100% vegan formula, pure citrus scent not tested on animals
  • 91% said hair is healthier, smoother and not weighed down

Results observed in 35 people after 21 days
Excessive formulation of 40+ ingredients can imbalance hair and leave residue on hair


  • K18Peptide - Acts as a protective shield, reducing protein loss that normally occurs when washing hair, keeping hair soft, strong, healthy and clean.
  • Optimal pH - maintains a sealed cuticle during washing to protect color and maintain natural moisture levels (the average professional shampoo does not have an optimized pH, the common pH of 6 can upset the hair + scalp balance).
  • Plant-derived surfactants* - create high lather + cleansing power without disturbing hair or leaving buildup on hair or scalp.

How to use

  1. Gentle enough to use with every wash.
  2. Massage into hair and target the scalp.
  3. Rinse thoroughly.
