Final answer:
Highlighting shampoo colors are prepared by combining Temporary haircolor, hydrogen peroxide, and shampoo.
Step-by-step explanation:
Highlighting shampoo colors are prepared by combining Temporary haircolor, hydrogen peroxide, and shampoo. Temporary hair color does not permanently alter the hair's structure and typically washes out after a few washes. Hydrogen peroxide is used to bleach the hair, creating a lighter base for the highlighting color. The shampoo helps distribute the color evenly throughout the hair.
