A Cold Wave Perm is a hair treatment that creates curls or waves using a cold solution instead of heat. This method involves applying a chemical solution to the hair, which helps to reshape it into curls while minimizing damage. The process is generally gentler than traditional heat perms, making it suitable for various hair types. During a Cold Wave Perm, the hair is wrapped around rods, and the cold solution is applied to set the curls. The results can last for several months, providing a natural-looking wave or curl pattern. This technique is popular for those seeking a low-maintenance hairstyle.
