What term describes the use of translucent color on previously colored hair?

The term that describes the use of translucent color on previously colored hair is glazing. This process involves applying a semi-permanent or demi-permanent color that enhances, tones, or adds shine to the existing hair color without providing full coverage. Glazing helps to refresh faded color, modify tone, or add depth while maintaining the hair's natural dimension, making it ideal for hair that has been colored previously.

Highlighting is a technique that lightens sections of the hair to create contrast, not specifically aimed at enhancing or altering existing color translucently. Color correction is a more involved process aimed at correcting unwanted tones or color results in the hair. Balayage is a technique that involves hand-painting highlights onto the hair for a more natural, sun-kissed look, rather than working with existing color in a translucent manner. Thus, glazing is the fitting choice for this specific context.
