Temporary hair color treatments are designed specifically to coat the hair shaft rather than penetrate it. These products typically contain large color molecules that cannot enter the cuticle layer of the hair. As a result, temporary colors can easily be washed out after a few shampoos, making them ideal for those looking for a short-term change or who want to experiment with vibrant shades without long-term commitment.

In contrast, permanent colors and demi-permanent colors involve chemical processes that allow them to penetrate the hair shaft for longer-lasting results. Permanent hair color uses a process of oxidation to enable the color to become trapped within the hair, while demi-permanent also partially penetrates but does not provide as much coverage and durability as permanent. Highlights typically involve using bleach or lightening agents to create lighter strands, which also penetrate the hair's outer layer. Therefore, temporary hair color stands out as the only option that remains superficial, affecting only the outer surface of the hair.
