What does the term "scissor-over-comb" refer to in barbering?

The term "scissor-over-comb" specifically refers to a method used by barbers to achieve blending and tapering of hair lengths. This technique is particularly effective for cutting shorter hairstyles, where precision and control are crucial. By positioning the comb against the scalp and using scissors to cut the hair above the comb, barbers can create a smooth transition between different lengths, effectively blending longer hair into shorter sections.

The comb acts as a guide, allowing the barber to control the length of the hair being cut. This method helps achieve clean edges and a uniform look, which is often desired in men's haircuts or fade styles. It is a staple technique in barbering that demonstrates skill in blending, making this choice the correct answer.

While other options mention techniques related to hair, they do not specifically describe the blending and tapering process that "scissor-over-comb" embodies.
