A permanent wave, commonly known as a perm, is a hair treatment that uses a chemical solution to alter the hair's structure, resulting in defined curls or waves. This process became popular in the mid-20th century, making it a prominent choice for individuals seeking a long-lasting change in their hair texture.
Perms offer numerous benefits, including the ability to add volume, enhance curls, and create a more defined and stylish look. Historically, perm solutions have evolved to become milder and less damaging, reducing the risk of hair breakage or damage.
