Which haircutting technique involves cutting the hair at a 90-degree angle?

The technique involving cutting the hair at a 90-degree angle is known as layering. This method creates layers in the hair, which can add volume and texture. When hair is cut at this angle, it allows for the top layers to be shorter while maintaining length in the bottom layers. As a result, this technique enhances movement and helps to remove weight from the hair without sacrificing overall length.

Layering is particularly beneficial for creating styles that appear fuller and more dynamic, allowing for versatility in styling options from curls to straight looks. This technique contrasts sharply with blunt cutting, which typically entails cutting the hair straight across without any angle to preserve length and weight uniformly. Other techniques, like texturizing or point cutting, also have specific purposes related to creating texture or softening edges but do not involve cutting the hair at a 90-degree angle.
