Which barbering technique has crossed over into cosmetology?

Scissor over comb is a barbering technique that has successfully crossed over into the realm of cosmetology because of its versatility and effectiveness in achieving various styles. This method allows stylists to create clean blends and textures, making it particularly useful for both men's and women's haircuts. The technique involves using a pair of scissors to cut hair while holding it with a comb, enabling precise control over the length and layering of the hair.

Its application goes beyond traditional barbering styles, as it can be adapted for modern looks, textured cuts, and adding volume, making it a valuable skill in a cosmetologist's toolkit. This crossover indicates its importance in achieving contemporary hairstyles that cater to diverse client needs. The other techniques listed, while applicable in their specific realms, do not have the same level of integration into cosmetology practices that scissor over comb does.
