Highlighting hair using foil is a technique for selectively lightening strands of hair to create a highlighted or streaked effect. It involves applying a bleaching agent to sections of hair that are wrapped in foil, which helps to isolate and protect the highlighted areas from the rest of the hair.
This technique has several benefits. Firstly, it allows for precise and controlled lightening, as the foil prevents the bleach from spreading to unwanted areas. Secondly, it creates a more natural-looking highlighted effect, as the lightened strands are blended with the darker base color. Additionally, foil highlighting is a relatively low-maintenance technique, as the highlights typically last for several months before needing to be touched up.
