The primary purpose of highlights in hair treatment is to add dimension and brightness to hair. When highlights are applied, they create contrast with the base color, giving the hair a multi-tonal effect that can enhance texture and movement. This technique reflects light differently than the surrounding hair, which can create the illusion of depth, making the hair appear fuller and more vibrant.

This approach is often used to brighten up a hairstyle without altering the entire color, allowing for a more natural and sun-kissed look. The process of highlighting can also help frame the face and accentuate certain features, contributing to a fresh and lively appearance. In contrast, other options such as completely coloring the hair, minimizing volume, or straightening curls do not align with the intended effect that highlights offer, which focuses on enhancing and creating visual interest rather than making drastic changes.
