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 curlers to shape it. Once the desired curl 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. Perming can be done on various hair lengths and textures, making it a popular choice for those looking to change their hairstyle. However, it is essential to follow proper aftercare to maintain the curls.
