What is the primary purpose of a perm?

The primary purpose of a perm is to create curls or waves in the hair by altering its structure. This is accomplished through a chemical process that breaks and reformulates the bonds in the hair's cortex, allowing it to take on a new shape. During a perm, the hair is wrapped around rods or rollers, and a chemical solution is applied, which changes the hair's natural pattern. After the desired curl or wave is achieved, a neutralizing solution is used to set the new shape in place. This transformation allows individuals to achieve longer-lasting curls or waves that can enhance their style and texture.

In contrast, while straightening hair is an entirely different treatment, it focuses on altering the hair structure to create a smooth, sleek appearance rather than enhancing curls or waves. Coloring the hair involves different chemical processes and does not fundamentally change its structure in the way a perm does. Similarly, moisturizing and nourishing the hair pertains to overall hair health and maintenance, rather than changing the hair's texture or shape. Each of these processes serves distinct purposes that do not align with the primary function of a perm.
