What method can be used to create highlights in the hair?

Foiling is a method used to create highlights in hair by applying hair dye or lightener to selected sections of hair using foil. This technique allows for the efficient application of color while isolating the strands to achieve a defined, contrasting look. The foils work to trap heat, which can enhance the lightening process, resulting in vibrant highlights.

This method offers versatility in the placement and intensity of highlights, making it a popular choice among hairstylists. By using foils, the stylist can manage the amount of lightener on each strand and control the blending between the natural hair color and the highlights.

In contrast, shampooing is a cleansing process and does not alter hair color. Color rinsing involves applying a temporary color that does not achieve the same level of highlight as foiling, as it generally washes out over time and does not create the same contrast. Hair straightening is a technique focused on altering the texture of hair rather than its color and would not facilitate the creation of highlights.
