Perming is a hair treatment that creates curls or waves in straight hair. The process involves applying a chemical solution to the hair, which breaks down its natural structure. After the solution is applied, the hair is wrapped around rods or rollers to shape the curls. Once the desired curl pattern is achieved, a neutralizer is used to set the new shape. The results of a perm can last several months, depending on hair type and care. There are different types of perms, including digital perm and cold perm, each offering unique styles and effects. Proper maintenance is essential to keep permed hair healthy and vibrant.
