Which haircutting technique involves cutting hair at an angle?

Layering is a haircutting technique that involves cutting the hair at an angle, which creates varying lengths throughout the hair. This technique adds volume and movement by removing weight from the hair and allowing the underlying layers to fall into place, creating a soft, blended look. The angled cuts help achieve a more dynamic shape and can enhance the natural texture of the hair.

In contrast, blunt cutting refers to cutting the hair straight across, resulting in a uniform length. Texturizing typically involves techniques that remove bulk from the hair without changing the overall length significantly, and point cutting is a technique used to soften the ends of a haircut by cutting the tips of the hair at an angle, but it does not involve creating distinct layers like layering does. Therefore, layering is the correct choice for the technique that specifically involves cutting hair at an angle.
