The main purpose of a perm in hairstyling is to create curls or waves. A perm, short for permanent wave, involves using a chemical process to alter the structure of the hair, which allows it to maintain a curly or wavy shape for an extended period. The process typically involves wrapping the hair around rods and applying a chemical solution that breaks down the hair's natural protein structure, allowing it to take on the new shape.

When performed correctly, a perm can add texture and body to the hair, making it a popular choice for those looking to enhance their hairstyle with curls or waves. This technique can be particularly beneficial for individuals with straight hair who desire more volume and movement. The versatility of perms also allows for different types of curls, from tight ringlets to looser waves, depending on the size of the rods used and the formulation of the perm solution.

While other options involve manipulating hair texture, they do not align with the primary goal of a perm, which focuses specifically on introducing curls or waves rather than straightening, removing frizz, or adding volume in a non-curling manner.
