Hydrogen peroxide used with most high-lift color to provide maximum lift in one step is _________ volume.

  1. 40

  2. 20

  3. 30

  4. 50

The correct answer is: 40

Hydrogen peroxide is commonly used in hair dyeing to provide lighter shades or "lift" to the hair. This process is known as high-lift color and requires a higher volume of hydrogen peroxide. Since the options are measured in volume, it is important to choose the highest option which is 40. Options B, C, and D are all lower volume levels and would not provide maximum lift in one step. Therefore, the most accurate answer is A.
