What is the purpose of using a processing cap during chemical treatments?

The purpose of using a processing cap during chemical treatments is to maintain heat and accelerate the processing time. When a chemical treatment such as a perm, relaxer, or hair color is applied, warmth can enhance the efficacy of the product. The heat trapped by the cap allows the ingredients to penetrate the hair more effectively, which can lead to a better overall result in terms of color development or texture alteration.

While other options may involve aspects of the salon experience—like client comfort and protection—the primary function of the processing cap is its role in temperature management during the chemical process. Maintaining warmth is crucial for achieving the desired results, making the processing cap an essential tool in chemical treatments.
