2. Enriched with 1% Hyaluronic Acid Complex for Deep Hydration

It fights the first visible sign of damage—dryness—while providing 1.9x more hydration and 82% glossier color results . The acidic pH helps seal the cuticle, preserving cortex integrity and providing vinyl shine .

3. 3-in-1 Professional Tool: Gloss, Tone & Refresh

• What it does: Dia Light is a 3-in-1 professional tool specifically designed for three key services: glossing adds shine and manageability; toning neutralizes unwanted undertones after lightening or balayage; and refreshing revives faded color on lengths and ends .

6. Mixable with 6, 9, or 15 Volume Developer for Customized Results
