A digital perm is a hair treatment that creates soft, natural-looking curls using heat and chemicals. Unlike traditional perms, which use cold solutions, digital perms involve heated rods that help set the curls. This process allows for more defined and longer-lasting waves, making it popular for those seeking a low-maintenance hairstyle. During the treatment, a stylist applies a chemical solution to the hair, wraps it around heated rods, and then uses a digital machine to control the temperature. The result is bouncy, textured curls that can last for several months, providing a stylish option for various hair types and lengths.
