Which line is typically utilized for layering in haircutting?

Layering in haircutting is primarily achieved through the use of diagonal lines. These lines create a sense of movement and softness, which is essential for the layered look that many styles aim for. Diagonal lines allow the hair to be cut at various angles, resulting in textures and dimensions that enhance the hairstyle's overall shape and flow.

When cutting with diagonal lines, the hairstylist can elevate sections of hair, creating layers that blend smoothly into one another. This technique is important because it can add volume and remove bulk without compromising the integrity of the hair. The angle at which the hair is cut determines how the layers will fall and how much volume will be achieved, making diagonal lines a fundamental aspect of the layering process in haircutting.

In contrast, horizontal lines typically create a heavier, more blunt look, vertical lines focus on length and weight distribution, and curved lines are often used to create softness along the perimeter of a style rather than for layering specifically. Thus, diagonal lines are most effectively employed for layering in haircutting.
