What is the purpose of using foils in hair highlighting?

Using foils in hair highlighting serves a key purpose of protecting the surrounding hair from color. When highlights are applied, foils isolate sections of hair that are to be colored, preventing the dye from spreading to adjacent strands. This is particularly important for achieving clean, defined highlights, as it allows for precision in application and helps maintain the integrity of the natural hair color in the sections not intended for coloring.

The use of foils not only enhances the effectiveness of the highlighting process by ensuring that only the selected hair strands are affected, but it also allows for better control over the processing time and the overall results. This precision in technique enhances the overall look and quality of the highlighting service, contributing to customer satisfaction and the stylist’s reputation for skill.
