Final answer:
Color-depositing shampoos are designed to temporarily adhere color molecules to the hair's cuticle, providing a short-term color boost without the commitment of permanent or semi-permanent dyes.
Step-by-step explanation:
The type of shampoo that contains temporary color molecules which adhere to the outer cuticle of the hair and deposit color is known as a Color-Depositing Shampoo. These shampoos offer a quick and non-commital way to enhance hair color. The pigments in color-depositing shampoos coat the surface of the hair, refreshing the color temporarily until the next wash. Unlike permanent hair coloring, which chemically alters the hair's structure, or semi-permanent dyes that last several washes, color-depositing shampoos provide a subtle change that can help maintain hair color between salon visits or cover greys in a pinch.
Users should be aware that these shampoos can't lighten the hair as bleaching can; instead, they add a hue to the existing hair color. The final effect will depend on the individual's original hair color and porosity. Additionally, these shampoos may contain conditioning agents like silicone to improve the hair's feel and appearance alongside color enhancement.
