OUAI Detangling and Frizz Fighting Leave-In Conditioner
by OUAI · hair_care
Editor's Take
Quaternium-91 and heat-activated silicones deliver genuine detangling and frizz control, but the cyclic silicone base and fragrance load push this far from clean.
Four-pillar formula scores
- Efficacy: 8.2 / 10
- Modern Tech: 7.5 / 10
- Clean Beauty: 1.0 / 10
- Sustainability: 0.4 / 10
The Verdict
This is a technically sophisticated leave-in built on modern cationic chemistry and heat-responsive polymers, not basic oils or legacy slip agents. The 11-amino acid complex and biomimetic pea protein add structural support beyond surface cosmetics, and the efficacy is strong , it genuinely detangles and controls frizz. The trade-off is environmental: Cyclopentasiloxane dominates the base, and the formula includes BHT, EDTA, and a heavy fragrance load with eight disclosed allergens. Worth it for performance-first users who prioritize immediate manageability over clean credentials.
