DEFINE — Powered by TriCore Complex™

Within the Define System, TriCore Complex™ supports curl pattern clarity and shape retention without stiffness.

Its balanced conditioning and film-forming coordination allow definition to remain flexible, touchable, and consistent through wear. Curl separation, surface smoothness, and elongation control are maintained without buildup.

The result is definition that responds naturally to movement and environment.
