Technical treatment support for hair damaged by frequent heat styling
Flat irons • Blow dryers • Curling irons

Developed as a technical support step within the Intensive Repair system, Must Use enhances fiber recovery, helps stabilize the hair structure, and prepares the hair for deeper treatments after repeated thermal exposure.

What it does

• Supports fiber recovery and stabilization

• Helps balance the hair structure after cleansing

• Enhances absorption of subsequent treatments
