Perming is a chemical service that specifically alters the texture of the hair by creating permanent curls or waves. This process involves the application of a chemical solution that breaks down the disulfide bonds in the hair's structure, allowing the hair to be reshaped around rods or curlers. Once the desired shape is achieved and set, a neutralizing solution is applied to reform the bonds in the new shape, resulting in lasting curls or waves.

Coloring, highlighting, and conditioning do not modify the fundamental texture of the hair, although they can enhance its appearance or improve its health. Coloring and highlighting primarily focus on changing the hair color, while conditioning treatments are designed to improve moisture and manageability without altering the structural properties. Thus, perming is the only option that specifically and effectively changes the hair’s texture.
