Mix with a Color Fusion in a 1:1 ratio with 10, 20, 30 or 40 Volume Pro-oxide Cream Developer for up to 4 levels of lift. Can then be applied with a bowl and brush or bottle using a Traditional or Modern Virgin Application.
Apply color generously using fine 1/4" diagonal partings. Cross-check application. Process at room temperature for 35-45 minutes. Follow with Color Extend Shampoo and Conditioner.
NOTE: No other developer may be substituted for Pro-oxide Cream Developer. To do so would cause unpredictable results.
