Which haircut technique requires the use of a razor?

The technique that involves the use of a razor is slicing. Slicing is employed to create soft, textured edges and can help to remove bulk from hair without altering the overall length dramatically. The razor glides through the hair in a slicing motion, allowing for a more seamless and blended finish, which is particularly helpful for creating movement and enhancing the natural texture of the hair.

Other techniques involve different tools or methods. Point cutting, for example, uses scissors to snip into the ends of the hair at an angle to create texture and remove weight but does not require a razor. Clipping usually refers to using clippers for cutting hair and is more suited for blunt cuts than the soft, textured styles that slicing achieves. Layering can be done with various tools, including scissors, but the specific use of a razor in slicing is what sets this technique apart in terms of the finesse and texture it provides.
