K18 PEPTIDE PREP Detox Shampoo

Clarifying Detox Shampoo for Product Buildup, Excess Oil & Minerals

K18 PEPTIDE PREP Detox Shampoo is a colour-safe clarifying shampoo designed to deeply cleanse the hair and scalp by removing product buildup, excess oil, metals and minerals that can accumulate over time.

Powered by K18PEPTIDE™ and formulated with activated charcoal and salicylic acid, it creates a cleaner foundation for healthy-looking hair and is particularly useful before K18 repair treatments when buildup may interfere with your haircare routine.

This is a periodic detox shampoo, not automatically your shampoo for every wash.

Best For

  • Styling-product buildup
  • Dry shampoo residue
  • Excess oil and scalp buildup
  • Hard-water mineral accumulation
  • Hair exposed to metals and environmental impurities
  • Hair that feels heavy, coated or difficult to style
  • Colour-treated hair needing a colour-safe clarifying option
  • Preparing the hair for a K18 repair treatment

Why You'll Love It

  • Provides a deeper cleanse than a regular shampoo
  • Helps remove product and oil buildup
  • Helps remove mineral and metal accumulation
  • Contains activated charcoal to help absorb impurities
  • Contains salicylic acid to support effective cleansing
  • Formulated with K18PEPTIDE™
  • Colour-safe
  • Creates an ideal starting point for a K18 repair routine

K18 PEPTIDE PREP Detox or Your Regular Shampoo?

Choose PEPTIDE PREP Detox when buildup, excess oil, minerals or residue are making the hair feel coated, heavy or less manageable.

Choose K18 Damage Shield pH Protective Shampoo for regular cleansing when you want ongoing K18 maintenance without the deeper clarifying action of a detox shampoo.

Think of PEPTIDE PREP Detox as your periodic reset and Damage Shield Shampoo as your regular K18 cleanser.

K18 PEPTIDE PREP Detox or Kevin Murphy MAXI.WASH?

Both are professional clarifying shampoos, but they fit slightly different routines.

Choose K18 PEPTIDE PREP Detox when you want deep cleansing for product buildup, excess oil and mineral or metal accumulation, particularly when you are using the K18 Leave-In Molecular Repair Hair Mask for damage repair.

Choose Kevin Murphy MAXI.WASH when you want a periodic deep-cleansing reset that integrates naturally into a Kevin Murphy routine before an appropriate Kevin Murphy conditioner, masque or treatment.

Neither is automatically better. Choose according to your buildup concerns and the treatment system you plan to use afterward.

Build Your K18 Detox & Repair Routine

  1. Detox: Use K18 PEPTIDE PREP Detox Shampoo periodically when buildup, oil, minerals or residue need to be removed.
  2. Repair: When using the K18 Leave-In Molecular Repair Hair Mask, towel-dry after shampooing and apply the treatment according to its directions. Do not apply conditioner before the K18 mask.
  3. Wait: Allow the K18 Leave-In Molecular Repair Hair Mask to work for 4 minutes before adding other products.
  4. Protect: Add K18 HeatBounce when dedicated heat protection is needed before blow-drying or hot-tool styling.
  5. Finish: Add K18 Molecular Repair Hair Oil when additional smoothing, frizz control and shine are desired.

When Should I Use Damage Shield Shampoo Instead?

If your hair does not need clarifying, use K18 Damage Shield pH Protective Shampoo for your regular cleansing routine.

This distinction is important: PEPTIDE PREP Detox removes accumulated buildup; Damage Shield is designed for regular protective cleansing. You do not need to deep-clean the hair every time you shampoo.

Can I Use K18 Detox With Other Brands?

Yes. PEPTIDE PREP Detox Shampoo can be used before treatments and conditioners from other professional haircare brands when a deeper cleanse is needed.

For example, you may use K18 Detox to remove accumulated buildup and then return to a Kevin Murphy, amika, OLAPLEX, Eleven Australia, Neuma or other professional routine selected for your primary hair concern.

If you are specifically using the K18 Leave-In Molecular Repair Hair Mask, follow the K18 treatment protocol rather than automatically adding a conventional conditioner before the mask.

How to Use

Use periodically when the hair needs deeper cleansing. Massage into the hair and scalp, focusing on areas where oil and product buildup accumulate. Rinse thoroughly and follow with the treatment or conditioning routine appropriate for your hair.
