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

K18 Peptide Prep™ Detox Shampoo is a color-safe clarifying shampoo that gently removes dirt, oil, metal minerals and product buildup to create a clean canvas for the K18 mask.

Designed as a weekly or as-needed deep cleanse, this activated charcoal and salicylic acid formula targets residues from styling products and hard water without stripping the hair's natural moisture. It pairs K18's patented peptide technology with ingredients inspired by skincare to absorb impurities at the scalp while protecting color and protein integrity. Use it before your K18 mask or when hair feels weighed down to restore manageability and a fresher scalp feeling.

How does this shampoo remove buildup without stripping my hair?

The formula balances clarifying actives with protective peptide technology. Activated charcoal and salicylic acid draw out oils, metals and product residue, while the K18PEPTIDE reduces protein loss and helps preserve hair strength and elasticity. The pH-optimized lather clears deposits yet leaves moisture and color intact.

• Activated charcoal absorbs impurities from hair and scalp.
• Salicylic acid helps loosen sebum and trapped product residue.
• K18PEPTIDE reduces protein loss compared with harsh chelators.
• pH-optimized formulation protects color and shine.

When should I use Peptide Prep Detox Shampoo in my routine?

Use this detox shampoo once a week or any time hair feels heavy, greasy, or coated by minerals from hard water. It’s intended as a reset before treatments—especially the K18 mask—so product actives can penetrate more effectively. If you live in a hard-water area or use many styling products, occasional extra washes are suitable.

• Weekly prep before deep treatments or hair masks.
• As-needed cleanse after heavy product use or hard-water exposure.
• Repeat wash option when residue persists after a single clean.

Will it keep my color looking fresh and my hair feeling strong?

This shampoo is formulated to be color-safe and to minimize protein loss while clarifying. Clinical testing shows significant removal of buildup and metals after one wash, helping color reflect light more evenly and maintain vibrancy. The peptide presence supports hair structure so strands feel resilient rather than brittle.

• Color-safe surfactant system to prevent premature fading.
• Reduces copper and mineral deposits that dull color.
• K18PEPTIDE helps maintain hair strength during detoxing.

How do I use it for best results?

Replace your regular shampoo with this detox formula once weekly or when build up is noticeable. Apply to wet hair, massage into scalp and lengths to emulsify oils and lift deposits, then rinse thoroughly. Repeat if needed and follow with the K18 mask for optimal repair and slip.

• Use in place of regular shampoo 1x weekly or as needed.
• Massage thoroughly into scalp and hair; rinse completely.
• Repeat a second wash if hair remains weighted down.
• Finish with the K18 mask for best restoration and styling results.

Who is this for: K18 Peptide Prep™ Detox Shampoo suits anyone needing a targeted deep cleanse—people living with hard water, those who use heavy styling products, or anyone prepping hair for a professional treatment or a K18 mask. It’s formulated for color-treated and natural hair types that require effective impurity removal without compromising protein content or color vibrancy.
