K18 Biomimetic Hairscience DAMAGE SHIELD pH Protective Shampoo
by K18 · hair_care
Editor's Take
K18 puts serious repair technology into the wash step, though its detergent-forward Sodium C14-16 Olefin Sulfonate base is less gentle than the premium pitch suggests.
Four-pillar formula scores
- Efficacy: 8.4 / 10
- Modern Tech: 8.8 / 10
- Clean Beauty: 7.6 / 10
- Sustainability: 8.7 / 10
The Verdict
Efficacy is Excellent: sh-Oligopeptide-78 supports molecular repair, while Panthenol and Glycerin help limit wash-day dryness. Clean is Excellent too, though Sodium C14-16 Olefin Sulfonate brings irritation and environmental trade-offs, with fragrance a secondary caveat. The pH-controlled, sulfate-free formula is a credible treatment shampoo for damaged or color-treated hair, especially with frequent washing. It earns its splurge status on technology, not exceptional mildness.
