Which practice involves creating a hairstyle by wrapping hair around rods or rollers?

The practice of creating a hairstyle by wrapping hair around rods or rollers is referred to as perming. This technique involves the use of a chemical solution that breaks down the hair's natural structure, allowing it to be reshaped. When hair is wrapped around the rods or rollers, the solution enhances the curl pattern, transforming straight hair into curly or wavy hair. Once the desired curl formation is achieved, a neutralizing solution is applied to lock in the new shape. The end result is a hairstyle that maintains its curls or waves until new hair growth occurs.

In contrast, texturizing generally refers to methods used to create movement or reduce bulk in the hair, but it doesn't specifically involve wrapping hair around rods or rollers. Cutting pertains to removing length or altering the shape of hair, while coloring focuses on changing the hair's color rather than its texture or shape. Thus, perming is the specific practice that fits the description provided in the question.
