K18 Detox Shampoo — Color-Safe Clarifying Shampoo, 8.5 fl oz with Activated Charcoal & Salicylic Acid

K18 Peptide Prep™ Detox Shampoo is a color-safe clarifying wash that gently lifts product buildup, excess oils and metals from hard water to reset hair and scalp in a single use.

Formulated with activated charcoal and salicylic acid, this clarifying shampoo is designed to create a clean foundation before treating with the K18 mask. Its skincare-inspired blend targets residue and sebum while the patented K18PEPTIDE helps preserve protein and color integrity. Use it weekly or as needed to restore hair manageability, clarity, and to improve how treatments absorb.

How quickly does this shampoo remove buildup and residue?

In lab testing, the formula removes large amounts of product residue, sebum and copper after one application, giving hair a visibly cleaner feel. The activated charcoal adsorbs impurities while salicylic acid helps loosen excess oils at the scalp for easy rinsing.

• Single-wash efficacy demonstrated for product buildup, sebum and copper reduction
• Activated charcoal attracts and binds surface impurities
• Salicylic acid exfoliates and clarifies the scalp without harsh stripping

Will this shampoo strip my hair color or natural moisture?

This detox is pH-optimized and formulated to be color-safe, so it cleans without aggressively removing dye or essential lipids. K18PEPTIDE is included to reduce protein loss, helping hair retain strength and elasticity even after a deep cleanse.

• Color-safe formulation protects salon-treated hair
• K18PEPTIDE helps minimize protein loss during cleansing
• Non-stripping surfactant system preserves moisture and softness

How should I use K18 Peptide Prep™ Detox Shampoo for best results?

Swap your regular shampoo for this detox wash one time per week or whenever hair feels weighed down. Massage into wet hair and scalp to work the product through, rinse thoroughly, and repeat only if necessary before applying the K18 mask or your regular conditioner.

• Use 1x weekly or as needed for buildup removal
• Massage into scalp and through lengths, then rinse completely
• Follow with K18 mask or conditioner for optimal treatment results

What makes the formula effective for hard water and tap water metals?

The combination of charcoal and targeted actives helps capture mineral and metallic particles common in hard water, while salicylic acid clears sebum that binds those particles to hair fibers. This leaves a cleaner canvas for styling and professional treatments.

• Activated charcoal adsorbs metal and mineral contaminants
• Salicylic acid helps lift sebum that traps metals to hair
• Designed to improve outcomes when followed by hair treatments

Who is this for: K18 Peptide Prep™ Detox Shampoo is suited for anyone with frequent product use, exposure to hard water, oily scalp concerns, or color-treated hair that needs a gentle but effective reset. It’s ideal for people preparing hair for intensive treatments or those who want a clearer, lighter feel without sacrificing strength or color integrity.
