Cleanse and Protect Hair Without Compromise

Meet the K18 DAMAGE SHIELD pH Protective Shampoo, a color-safe, pH-balanced shampoo that gently removes dirt, oil, and buildup while protecting the hair cuticle from damage. Formulated by K18 Biomimetic Hairscience, this sulfate-free shampoo helps maintain the ideal pH range to keep hair strong, smooth, and healthy between salon visits.

Strength Starts with a Balanced pH

Every wash with K18 DAMAGE SHIELD supports the hair’s natural acid mantle — a critical defense layer that helps prevent color fade, breakage, and dryness. Its biomimetic technology works in harmony with the K18 Peptide™, restoring resilience to chemically treated and heat-styled hair without stripping moisture.

Key Benefits

• Gently cleanses without disrupting the hair’s pH balance

• Shields hair from environmental aggressors and mechanical damage

• Strengthens and smooths the hair cuticle

• Safe for color-treated, bleached, and chemically processed hair

• Sulfate-free, silicone-free, vegan, and cruelty-free formula

How to Use

1. Apply a small amount to wet hair.

2. Massage into scalp and hair for a rich, gentle lather.

3. Rinse thoroughly.

4. For best results, follow with K18 Molecular Repair Hair Mask or your preferred conditioner.

The Science Behind K18 Biomimetic Haircare

Powered by K18 Peptide™, a patented sequence that reconnects broken keratin chains, K18 products work at the molecular level to reverse damage caused by bleach, color, heat, and chemical services. The DAMAGE SHIELD Shampoo complements the K18 repair system by keeping the hair’s pH balanced — ensuring long-lasting softness, strength, and shine.
