What technique is used to create volume in the crown area of a haircut?

Layering is a technique specifically designed to create volume in the crown area of a haircut. When hair is layered, different lengths are cut in such a way that some sections are shorter, allowing for natural lift and movement. This is especially effective in the crown area, where the hair can be shaped to add body and fullness. Layers can help prevent the hair from appearing flat by allowing the shorter layers to push the longer layers up, creating a more voluminous look.

Graduation, while it can also contribute to volume, primarily focuses on creating a structured shape rather than achieving overall fullness. Texturizing involves removing bulk and can enhance movement but does not serve the primary function of adding volume. Clipping is not a recognized technique in this context and is more about securing hair in place rather than altering its volume or shape.
