Which hydrogen peroxide developer is used with most high-lift colors?

10 volume
20 volume
30 volume
40 volume

The correct answer is: 40 volume

The appropriate hydrogen peroxide developer used with most high-lift colors is 30 volume. This developer is effective in achieving a higher level of lift while also providing the necessary tone to the hair. High-lift colors often require a stronger developer to ensure that the color can effectively lighten the hair while depositing the desired shade. While 40 volume developer is indeed a strong option that can provide maximum lift, it can also lead to excessive damage and over-processing of the hair, which is typically not ideal for achieving the subtle results often desired with high-lift colors. In most cases, 30 volume strikes a balance between adequate lift and hair health, making it the standard choice for high-lift formulations. This helps achieve a lighter result while maintaining the integrity of the hair, especially when working with previously colored or chemically treated hair.
