Homonym: perm (Hair)
A "perm," short for permanent wave, is a chemical treatment used to create curls or waves in hair. This process involves applying a solution that breaks down the hair's natural structure, allowing it to be reshaped around rods or curlers. Once the desired curl is achieved, a neutralizing solution is applied to set the new shape.
Perms can vary in size and tightness, from loose waves to tight curls, depending on the rods used and the technique applied. While popular for adding volume and texture, it's important to note that perms can also cause damage to hair if not done properly or if hair is already compromised.
