Our Take

Olaplex's first product built specifically for curls, and the most CGM-relevant launch the brand has made. Confirmed free of silicones, sulphates, and protein — a genuinely CGM-approved curl gel with the added benefit of Olaplex bond-building technology. The Curl Retention Compound (flexible polymers, plant collagen, sugars) provides medium all-day hold with humidity resistance up to 72 hours. No crunch. Apply to wet hair, scrunch upward, and air dry or diffuse. Won Allure Best of Beauty 2025 for Best Hair Gel.
