Which tool is primarily used for sectioning hair?

The tool primarily used for sectioning hair is hair clips. Hair clips are specifically designed to hold sections of hair in place while you work on different parts of the hair during styling or cutting. By using hair clips, you can effectively divide the hair into manageable sections, allowing you to focus on one area at a time, which helps ensure precision and uniformity in your work.

While brushes and combs can assist in smoothing or detangling hair before sectioning, they do not hold the hair in place. Scissors are essential for cutting hair but are not meant for sectioning; they are a finishing tool used after the sectioning process has been completed. Hence, hair clips are the most functional and appropriate choice for the task of sectioning hair.
