What type of hair colour is best known for providing a temporary solution without commitment?

The choice that identifies the type of hair colour best known for providing a temporary solution without commitment is temporary hair colour. This type of hair dye generally lasts for a very short period, often just a few washes. Temporary hair colour sits on the surface of the hair cuticle rather than penetrating it, which means it doesn't alter the hair structure or require a developer. As a result, it is easy to apply and wash out, making it an ideal option for those who want to experiment with different shades without long-term effects. This allows individuals to change their look for special occasions or try out bold colors they may not want to commit to permanently.

In contrast, permanent and semi-permanent colours involve formulas that either penetrate the hair shaft or require a chemical process that alters the hair structure, leading to longer-lasting results. Oxidative colours also require a developer to activate, resulting in a more permanent effect. Hence, temporary hair colour stands out as the option that emphasizes brief experimentation in hair styling.
