K18 DAMAGE SHIELD pH Protective Shampoo
by K18 · hair_care
Editor's Take
A patented peptide repair system built into a modern sulfate-free surfactant base , rare tech for a daily shampoo, though the petrochemical base and synthetic fragrance keep it from clean territory.
Four-pillar formula scores
- Efficacy: 8.8 / 10
- Modern Tech: 9.2 / 10
- Clean Beauty: 5.5 / 10
- Sustainability: 6.0 / 10
The Verdict
This is a cutting-edge shampoo that delivers molecular repair during the wash, not just after. The K18Peptide and pH-shielding formula place it in elite technical territory , efficacy and technology scores reflect genuine innovation. The sulfate-free surfactant system cleanses effectively without the cuticle damage of older chemistry. The trade: clean and sustainability scores sit in the mid-range due to petrochemical-derived surfactants and undisclosed fragrance. Worth it if you want repair-grade performance in a daily cleanser and can live with a formula that prioritizes fiber integrity over green chemistry alignment.
