K18 Damage Shield pH Protective Shampoo is a colour-safe, pH-optimised shampoo powered by patented K18PEPTIDE™ to gently but effectively cleanse while maintaining hair health.

Designed for damaged, coloured, or frequently styled hair, this daily shampoo supports the scalp microbiome and protects the hair fibre with every wash. Plant-derived surfactants remove dirt, oil, and buildup without stripping, leaving hair clean, soft, and strong.

How It Works

This shampoo uses plant-derived surfactants to break down oil, buildup, and impurities while respecting the scalp and hair structure. Instead of cleansing at a harsh, alkaline pH, the formula mimics the scalp’s natural pH range, helping the cuticle remain smooth and compact.

This supports:

• Reduced frizz and surface roughness
  
• Better colour retention
  
• Higher shine and smoother texture
  
• A healthier scalp environment
  

Microdosed K18PEPTIDE™ works inside the hair fibre to help minimise protein loss and maintain strength.
