A 30 volume hydrogen peroxide solution will generally lift the hair how many more levels than a 20 volume solution?

Explanation:
Lift in color services is tied to the strength of the developer: stronger developers lift more pigment. A handy rule is that each 10-volume increase adds about one level of lift under typical conditions. So moving from 20-volume to 30-volume generally yields roughly one more level of lift. The exact amount can vary with hair history, porosity, processing time, and temperature, but the practical takeaway is that a 30-volume developer typically lifts about one level more than a 20-volume developer.
