- Measure one level scoop (1oz) of the Blondest Lightening System with Azulene into a non-metallic bowl.
- Add 2oz of the Blondest Cream Developer with Azulene (10, 20, 30, or 40 volume) and mix thoroughly with a non-metallic instrument until you reach a smooth, creamy consistency.
- Process until the desired level of lift is achieved, as indicated by the strand test. Rinse hair thoroughly with the appropriate Peter Coppola Keratin Concept Shampoo and Conditioner.

* This product contains light, violet pigments intended to neutralize yellow or brassy tones in very light (blonde, silver, white) hair. In hair that is highly porous or extremely light (especially white or silver), pigment may deposit and result in a subtle, temporary color cast. Always perform a strand test before full application. Adjust processing time, dilution, or pigment concentration for more delicate hair. Use clarifying or corrective color treatments to remove residual pigment if necessary.
