Question

A 30-volume hydrogen peroxide solution will generally lift the hair:

a) One to two levels
b) Three to four levels
c) Five to six levels
d) Seven to eight levels

Answer 1

A 30-volume hydrogen peroxide solution generally lifts hair color by three to four levels, based on various factors such as the natural color and condition of the hair.

Step-by-step explanation:

A 30-volume hydrogen peroxide solution is typically used to lift the hair color by three to four levels. The 'volume' of hydrogen peroxide refers to its strength or ability to release oxygen and, thereby, lighten the natural pigment of hair. This change in hair color depth depends on several factors, including the natural hair color, current hair condition, and the duration the product is left on the hair.
