What is the role of a cap during hair color applications?

The role of a cap during hair color applications primarily centers around its function in protecting the client's clothing and containing drips or mess associated with the coloring process. When applying hair color, it's common for the color to splatter or drip, especially when using liquid formulations. A cap serves as a barrier that prevents these substances from staining or damaging the client’s attire, thereby maintaining a clean and professional environment.

Additionally, a cap can help contain the hair during the coloring process, keeping it organized and easier to manage. While other options mention potential effects on color enhancement, warmth, or shine, these are not typical functions of a cap during a hair color application. The main focus is on protection and cleanliness, making this role critical in ensuring a comfortable and worry-free experience for the client.
