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

The panel of hair on which a roller is placed is referred to as the base. This term specifically denotes the section of hair that secures the roller in place and provides stability during the curling or styling process. Properly setting the roller on the base allows for effective curl formation and helps achieve the desired volume and shape in the hairstyle.

Understanding the concept of the base is crucial because it influences the overall outcome of the styling technique. The base serves as the foundation for the roller's positioning, which is essential for creating consistent curls or waves.

In contrast, the root refers to the part of the hair that is closest to the scalp, while the tip pertains to the ends of the hair strands. "Line" does not specifically relate to roller placement in hairstyling terminology and is less relevant in this context.
