L'ANZA Keratin Healing Oil Emergency Thermal Therapy Part A is the first step in a professional two-part intensive repair system designed for severely damaged, over-processed, or chemically-treated hair.

This 297ml treatment harnesses keratin and healing oils to penetrate the hair cortex, restoring strength and elasticity from within. When used with Part B and heat activation, it reconstructs compromised hair structure while sealing the cuticle layer. The luxurious oil-based formula provides deep nourishment and protection, transforming brittle, weakened strands into silky, resilient hair. Professional results require completing the full thermal therapy protocol for maximum restoration and shine.
