What is the outcome of using the foiling technique?

Using the foiling technique specifically results in highlighted or lowlighted strands in defined sections. This method involves wrapping selected sections of hair in foil after applying a lightener or color to them. The foil serves a dual purpose: it helps to isolate the strands being treated and enhances the effectiveness of the lightener or dye by trapping heat. As a result, this technique achieves a more controlled and deliberate outcome, allowing for a contrast between the treated sections and the rest of the hair.

This precision is what distinguishes foiling from other methods. For instance, uniform color across all hair would not apply in a technique where sections are distinctly treated. Similarly, random colored portions would imply a lack of structure, whereas foiling is about targeted application. A glossy finish without color change is unrelated to the purpose of foiling, which is to alter the color of specific strands, not just enhance shine. Therefore, the correct outcome of using the foiling technique is indeed highlighted or lowlighted strands in defined sections.
