What term describes the type of hair color applied for a short-term effect that can be easily removed?

Temporary color is specifically designed to provide a short-term effect on the hair and can be easily washed out with shampoo. This type of hair color typically contains large color molecules that do not penetrate the hair shaft, which means they only coat the outer layer of the hair. This allows for vibrant changes in hair color that can last from a few shampoos to a few weeks, depending on the product and hair type.

In contrast, permanent color involves the use of chemicals that create a lasting change by penetrating the hair shaft and altering its structure. Semi-permanent color, while it does not require a developer and typically lasts longer than temporary color, still does not provide the same level of longevity as permanent color. An oxidizing color refers to products that interact chemically with hair, usually involving a developer that causes a permanent change in hair color. Thus, the unique characteristic of temporary color makes it the correct answer for this question regarding easily removable hair color.
