What technique involves using a comb to section hair for cutting?

The technique that involves using a comb to section hair for cutting is the cutting line technique. This technique is essential in barbering and hairstyling as it helps create structured layers or achieve uniform lengths when cutting hair. By using the comb to section the hair, a barber can ensure that each part of the hair is cut at the correct angle and length, achieving a precise hairstyle. This method allows for better control and accuracy during the cutting process, making it a fundamental skill for barbers.

The other techniques mentioned do not primarily focus on sectioning hair with a comb for the purpose of cutting. Fingertip techniques generally refer to cutting styles that utilize finger placements and may not specifically require comb sectioning. Clipping techniques are usually associated with using clippers rather than a comb for sectioning. The comb-over technique is related to styling hair rather than the sectioning and cutting process itself.
