Final answer:
Color-enhancing shampoos or color rinses temporarily change hair hue and brightness by adhering to the hair cuticle. They often contain glycol distearate for a pearlescent effect and silicones for conditioning.
Step-by-step explanation:
Shampoos that adhere to the outer cuticle of the hair to temporarily change its hue and brightness are known as color-enhancing shampoos or color rinses. These products deposit color on the surface of the hair without penetrating the hair shaft, thus providing a temporary color change that typically washes out after a few shampoos. Color-enhancing shampoos are popular for boosting natural hair color, blending grays, or extending the life of color-treated hair. In addition to colorizing agents, many shampoos incorporate ingredients like glycol distearate to achieve a pearlescent effect and silicones for added conditioning benefits.
