K18 Detox Shampoo Color-Safe Clarifying Shampoo 16 fl oz — Activated Charcoal & Salicylic Acid

K18 Peptide Prep™ Detox Shampoo is a color-safe clarifying shampoo that gently removes dirt, oil, metals from hard water and heavy product buildup while protecting hair strength with the patented K18PEPTIDE.

Designed as a prep step for healthier-looking hair, this detox shampoo clears impurities from scalp and strands so treatments and masks perform better. The formula blends activated charcoal and salicylic acid to lift sebum and mineral deposits without stripping moisture, and the pH-balanced lather helps preserve color. K18 also incorporates its signature peptide technology to minimize protein loss during deep cleansing.

How will this shampoo improve my hair before treatments?

Clearing residue creates a fresh base so conditioners, leave-ins, and peptide treatments can penetrate more effectively. Removing oils and metal deposits prevents barrier interference and helps your follow-up products deliver consistent results.

• Removes dirt, excess oil and heavy product buildup to enhance product absorption
• Reduces metal deposits from hard water that can dull results
• Prepares hair for optimal performance from the K18 mask or other treatments

Is it safe for color-treated hair and everyday use?

This clarifying shampoo is formulated to be color-safe and pH-optimized, so it refreshes hair without aggressively stripping dyes. Use it selectively—about once weekly or as needed—rather than swapping it for a daily shampoo, to maintain vivid color and hydration.

• Color-protecting pH and gentle surfactants reduce fade risk
• Recommended once weekly or as needed for maintenance
• Helps prevent over-drying by avoiding harsh chelators

What key ingredients make it effective at detoxing?

The formula combines activated charcoal to adsorb impurities with salicylic acid to help lift sebum from the scalp. K18’s patented peptide is included to help limit protein loss during deep cleansing, supporting hair resilience and a healthy feel.

• Activated charcoal draws out dirt and pollution particles
• Salicylic acid helps loosen sebum and scalp buildup
• K18PEPTIDE helps reduce protein loss and preserve hair strength

How noticeable are the results after one use?

Clinical testing shows substantial removal of buildup after a single wash, which translates to an immediate cleaner scalp sensation and lighter, more flexible hair. Results may vary with hair type and the amount of buildup, but many users report improved manageability and a refreshed scalp feeling right away.

• Clinical findings: removes significant percentages of product residue, sebum, and copper after one wash*
• Creates a cleaner canvas for styling and treatments
• Rinses clean without leaving residue that weighs hair down

Who is this for: K18 Peptide Prep™ Detox Shampoo is intended for people who regularly use styling products, contend with hard water or visible mineral buildup, or want a clarified base before professional or at-home peptide treatments. It suits color-treated hair when used occasionally, and is useful for anyone seeking a deeper clean without sacrificing strand strength. Follow with a K18 mask or your preferred conditioner for best results.
