Chunky highlights or chunky streaks are precisely-placed wide sections of colored hair, usually in a contrasting color against a natural base color or another color. Popular on brown hair, chunky highlights have a bold and eye-catching effect.
Chunky highlights add depth and dimension to hair, and can create the illusion of thicker hair. They are also a great way to add a splash of color to your look without having to dye your entire head. Chunky highlights have been popular since the 1990s and have recently made a comeback.
