What is the purpose of Color Shampoo?

• A. Cleans the scalp and hair with water.
• B. Provides a deep conditioning treatment for dry hair.
• C. Adds permanent color to the hair.
• D. Temporary color molecules that adhere to the outer cuticle of the hair and deposit color.

Answer: (D)

Color shampoo deposits pigments on the hair’s outer layer, the cuticle. These temporary color molecules cling to the surface and add or refresh color, gradually washing out with each shampoo. It’s used to refresh shade between treatments or to tweak tone, not to permanently change hair color or provide a deep conditioning treatment. Other options describe cleansing, conditioning, or permanent coloring, which aren’t what color shampoo does.
