What service is typically offered to enhance the natural curl in hair?

Perming is a chemical treatment designed specifically to alter the structure of the hair to create curls or waves. This process involves applying a perm solution that breaks down the hair's natural bonds, allowing the stylist to shape it into curls or waves on rods. Once the desired curl pattern is achieved, a neutralizing solution is applied to re-form the bonds in their new shape. This results in enhanced natural curl or new curls altogether, giving the hair body and texture.

While other options such as using a curling iron can create temporary curls by applying heat, they do not change the hair's structure long-term. Hair straightening serves the opposite purpose by relaxing curls and creating a smoother, straighter appearance. Coloring simply alters the hair's pigment without affecting its texture or curl pattern. Therefore, perming stands out as the most effective and appropriate method for enhancing natural curl in hair.
