Why customers choose Remedies Beauty

K18 Peptide Prep™ Detox Shampoo is a color-safe clarifying cleanser that removes dirt, oil, metals and product buildup while preparing hair for the K18 mask.

This shampoo is formulated to deep-clean both hair and scalp without stripping essential moisture, blending activated charcoal and salicylic acid with K18’s patented peptide technology. It’s intended as a weekly or as-needed detox to lift impurities from hard water, tap water minerals and styling residues so treatments and color perform better and feel fresher.

How does this shampoo remove hard-water minerals and product residue?

The formula uses absorbent activated charcoal to capture impurities and salicylic acid to help clear sebum and other residues from the scalp. It’s designed to rinse away metals like copper and accumulated styling product, giving a cleaner base for follow-up treatments.

  • Activated charcoal absorbs oils and particulate buildup.
  • Salicylic acid helps dissolve sebum and loosen residue at the scalp.
  • pH-optimized lather aids in lifting minerals and rinsing them clear.

Will this shampoo strip my color or weaken hair?

This detox is formulated to be color-safe and to limit protein loss through the inclusion of the proprietary K18PEPTIDE. Unlike harsh chelating shampoos, it cleanses without aggressively removing dye or compromising hair structure when used as directed.

  • K18PEPTIDE helps preserve protein and hair integrity during clarifying washes.
  • Color-safe pH balance reduces fading compared with strong chelators.
  • Designed for periodic use rather than daily clarifying to protect color longevity.

How do I use Peptide Prep Detox for best results?

Replace your regular shampoo with this detox treatment once weekly or whenever hair feels weighed down. Massage into scalp and through lengths, rinse thoroughly, and follow with the K18 mask or your regular conditioner for optimized performance.

  • Use 1× weekly or as needed for buildup or hard-water effects.
  • Massage well into scalp to dislodge oils and mineral deposits.
  • Rinse fully and follow with K18 mask or a moisturizing step for best results.

What active ingredients should I expect and what do they do?

The shampoo combines activated charcoal, salicylic acid and the patented K18PEPTIDE to cleanse, clarify and protect. Each component targets a different source of buildup while aiming to maintain moisture balance and hair strength.

  • Activated charcoal: adsorbs surface impurities and environmental particles.
  • Salicylic acid: aids scalp exfoliation and oil removal.
  • K18PEPTIDE: helps reduce protein loss and supports hair resilience.

Who is this for: K18 Peptide Prep™ Detox Shampoo is ideal for anyone dealing with hard-water mineral deposits, visible product buildup, oily roots or dull hair from frequent styling. It’s especially useful for color-treated hair owners who need a clarifying wash that won’t aggressively fade dye or undermine hair strength, and for those prepping hair for the K18 restorative mask or other treatments.
