What is 'highlighting' in the context of hair treatment?

Highlighting refers to the technique of lightening specific strands of hair in order to create contrast and dimension within the overall hairstyle. By selectively lightening certain sections, the hair appears more vibrant, textured, and multidimensional, which can enhance a person's natural hair color and add visual interest. This technique is commonly used in various hair coloring styles to provide a sun-kissed effect or to elevate a base color.

The other options do not align with the concept of highlighting. Darkening strands of hair is a different technique known as lowlighting. Cutting hair pertains to haircutting methods rather than color treatments. Removing excess hair typically refers to hair removal techniques, which are not related to highlighting at all. Highlighting specifically focuses on altering the color of the hair strands to achieve the desired aesthetic effect.
