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

K18 Peptide Prep™ Detox Shampoo is a color-safe clarifying wash that gently removes dirt, oil, metal deposits and heavy product buildup while preserving hair strength with the patented K18PEPTIDE.

If your hair feels weighed down, lacks movement, or your color looks dull despite regular washing, mineral-rich hard water and product residue may be the cause. This detox shampoo combines activated charcoal and salicylic acid to lift impurities from the scalp and hair, while a pH-optimized, peptide-infused formula aims to protect hair proteins and color. It’s designed to create a clean foundation so follow-up treatments—like masks or conditioners—can perform better.

How does this shampoo remove buildup without stripping hair?

The formula uses activated charcoal to adsorb dirt and metals, plus salicylic acid to help clear excess sebum at the scalp. Unlike aggressive chelators, K18’s peptide technology is included to reduce protein loss and maintain hair strength, while the balanced pH keeps color from fading.

• Activated charcoal binds and lifts impurities from strands and scalp.
• Salicylic acid helps dissolve sebum and unclog follicles for a cleaner scalp.
• K18PEPTIDE is present to help mitigate protein damage during clarifying.
• pH-optimized lather minimizes color stripping compared with harsh detergents.

Will this shampoo work for hard water and metal buildup?

Yes—this product is formulated specifically to address residues deposited by hard tap water and metal ions. Clinical test results cited by the brand show substantial removal of common contaminants after a single wash, which can improve texture and manageability.

• Designed to remove mineral and metal buildup from hard water exposure.
• Helps reduce copper and other metal deposits that dull hair.
• Recommended for occasional use to reset hair between regular washes.

How often should I use the detox shampoo and how do I apply it?

Use the detox shampoo in place of your regular shampoo about once a week, or as needed if your hair feels heavy or clogged. Apply to wet hair, massage into scalp to loosen buildup, rinse thoroughly, and repeat if necessary for extra residue removal.

• Use 1x weekly or as-needed for deep cleansing.
• Massage into scalp and through lengths for even detoxification.
• Thoroughly rinse; repeat on very heavy buildup days.

Is it safe for color-treated and chemically processed hair?

The shampoo is formulated to be color-safe and includes K18PEPTIDE to help reduce protein loss, so it’s suitable for color-treated hair when used as directed. It’s a targeted clarifying step meant to precede conditioning or treatment products to restore manageability without accelerating color fade.

• Color-safe, pH-optimized formula helps protect dyed hair during detoxing.
• Peptide technology supports protein retention in processed hair.
• Best used before masks or treatments to maximize their effectiveness.

Who is this for: K18 Peptide Prep™ Detox Shampoo is intended for anyone whose hair suffers from visible or tactile buildup—people living with hard water, daily styling product users, swimmers, or those noticing limpness and dull color. It’s ideal as a weekly reset to refresh the scalp and strands while keeping color and hair strength in mind. If you need deeper restoration beyond cleansing, follow with a K18 mask or treatment for targeted repair.
