What is a characteristic of temporary hair color?

Temporary hair color is defined by its ability to coat the hair rather than penetrate the hair shaft. This characteristic allows for quick application and easy removal, making it ideal for clients looking to change their hair color temporarily, such as for special occasions or a short-term look. Since temporary hair colors are designed to wash out with shampoo, they do not have the staying power associated with semi-permanent or permanent colors, which can actually alter the hair structure and provide longer-lasting effects.

Furthermore, while temporary colors can come in a range of shades, including natural colors, they are often marketed with vibrant, unnatural shades to attract those seeking a bold temporary change. This means that while many temporary colors may lean towards the unconventional, it is not an absolute characteristic that they only come in unnatural shades. Thus, the statement that a characteristic of temporary hair color is that it lies on the hair's surface effectively captures the essence of its functionality and purpose.
