A chemical perm, short for permanent wave, is a hair treatment that uses chemicals to create curls or waves in straight hair. The process involves applying a solution that breaks down the hair's natural structure, allowing it to be reshaped around rods or curlers. After the desired curl pattern is achieved, a neutralizer is applied to set the new shape. This technique can provide long-lasting results, making it popular for those seeking a change in their hairstyle. However, it is essential to consider hair health, as the chemicals used can cause damage if not applied correctly. Regular maintenance and care are necessary to keep the hair healthy after a chemical perm.
