Which style of haircut is achieved using a layering technique?

The style of haircut that is achieved using a layering technique is long layers. Layering involves cutting the hair at different lengths, which can create volume and texture. In the case of long layers, specific sections of the hair are cut shorter than the overall length, giving a more dynamic and flowing appearance. This technique helps to remove bulk while still maintaining length, resulting in a look that can be styled in various ways.

The other options do not typically involve layering. A buzz cut is a uniform, very short haircut without layers, created using clippers for a consistent length all over. A fade involves a gradual shortening of hair length from the top down to the sides and back, which focuses on blending rather than layering. Similarly, a flat top features hair that is cut to a uniform length on the top while the sides are usually shorter, emphasizing a flat, geometric shape rather than layered texture. Thus, long layers distinctly stand out as the technique that effectively employs layering in hairstyling.
