Which tool is commonly used to section hair during a haircut?

The commonly used tool for sectioning hair during a haircut is the comb. A comb is essential in the hair cutting process because it allows the barber to neatly divide the hair into manageable sections. Sectioning is important for creating precise lines and ensuring an even cut throughout the hair.

By using a comb, barbers can also smooth out tangles and align the hair in the direction it will be cut, which is critical for achieving the desired style and maintaining control during the haircut. Other tools like brushes, scissors, and clippers serve different purposes in the grooming process; for instance, brushes are primarily for styling and smoothing, scissors are used for cutting, and clippers are used for shorter styles or tapering. However, when it comes to sectioning hair specifically, the comb is the most effective and standard tool used in the barbering industry.
