Temporary colors are hair dyes that provide a short-term change in hair color. They typically last from a few washes to a few weeks, depending on the product and hair type. These dyes are often used for special occasions or to experiment with different looks without a long-term commitment. Unlike permanent dyes, temporary colors do not penetrate the hair shaft. Instead, they coat the outer layer of the hair, making them easier to wash out. Common forms of temporary colors include sprays, gels, and conditioners, allowing for a variety of application methods and effects.
