What is a "fade" in haircut terminology?

In haircut terminology, a "fade" refers to a gradual blend from short to longer hair. This technique involves a seamless transition where the hair gradually increases in length from the bottom of the haircut toward the top. The skill in creating a fade is in achieving a smooth and natural-looking blend, which can enhance the overall aesthetic of the haircut. It is particularly popular in various hairstyles, especially in men's haircuts, and can vary in gradient intensity—ranging from low fades to high fades, depending on the desired look.

The other options describe different haircut techniques that do not capture the essence of a fade. For instance, a harsh line between hair lengths is the opposite of the intended effect of a fade, which is all about blending. Layering hair focuses on cutting hair at varying lengths to create texture and volume, rather than the gradual transition of lengths characteristic of a fade. Creating volume might involve different techniques, such as layering or curling, rather than the blending associated with a fade. Each of these alternatives highlights distinct concepts in hairstyling that differ from the smooth transition defined by a fade.
