Hair highlights are a popular hair coloring technique that involves lightening specific strands of hair to create contrast and dimension. This process can enhance the natural color of the hair and add depth, making the overall look more vibrant. Highlights can be applied in various styles, such as foiling or balayage, and can range from subtle to bold, depending on personal preference. The application of highlights typically involves using a bleaching agent or hair dye to lighten selected sections of hair. The results can vary based on the original hair color and the chosen highlight shade. Regular maintenance is often required to keep the highlights looking fresh and prevent noticeable regrowth.
