What is the primary function of a barber's comb when cutting hair?

The primary function of a barber's comb when cutting hair is to section the hair and guide the cutting process. A comb is an essential tool that helps the barber organize the hair into manageable sections, allowing for precision and control during the haircut. By sectioning the hair, the barber can ensure that each part is cut to the desired length and evenly blended, resulting in a polished finish.

The use of the comb also aids in controlling the hair's position, helping to create uniformity in the cut and allowing the barber to assess the length and shape as they work. This careful manipulation of sections is crucial for achieving the intended style and maintaining the client's satisfaction with the final result.
