What is the area called on which a roller or thermal iron is placed?

The area on which a roller or thermal iron is placed is referred to as the base. This term specifically denotes the part of the hair where the tool is applied, and it plays a crucial role in how styles are created and how curls or waves are formed. When rolling hair, the base affects the volume and hold of the style. The base is where the hair strands are anchored, making it essential for achieving the desired finish. Understanding this concept is vital for cosmetologists as it influences how styles set and how long they last, directly impacting client satisfaction.

The other terms mentioned, such as section, root, and tip, refer to different aspects of hair styling. A section is a part of hair that is divided for manipulation; the root refers to the base of the hair follicle where growth occurs; and the tip indicates the ends of the hair strands. While relevant in the context of hairstyling, these terms do not pertain specifically to the area where tools like rollers or hot irons are placed.
