What is the term for the panel of hair on which a roller is placed?

The correct term for the panel of hair on which a roller is placed is "Base." In the context of hairstyling, particularly when using rollers, the base refers to the area of hair that is next to the scalp and provides support for the roller itself. This is crucial for achieving volume and set in styles, as a solid base allows the hair to hold its shape after styling.

In contrast, while "Section" refers to the division of hair for cutting or styling, "Panel" is more of a general term and does not specifically apply to roller placement. "Circle" does not accurately describe any part of the roller placement process. Understanding this terminology is important for effective communication in the salon and for implementing styling techniques correctly.
