What is 40 vol added to achieve in a one-step colour service?

No change in color
Slight color change
Medium lift
Maximum lift

The correct answer is: Maximum lift

When 40 vol is added to a one-step colour service, the resulting color is expected to have the maximum amount of lift. This lift refers to how many levels the hair's natural color is lightened. This is achieved by using a higher volume developer, which contains more hydrogen peroxide and can lift the hair color more effectively. Option A is incorrect because adding 40 vol will definitely result in a noticeable change in color. Option B is also incorrect because a slight color change can be achieved with a lower volume developer. Option C is incorrect because medium lift is usually achieved with a 30 vol developer, not 40 vol.
