Which type of distribution is utilized to create uniform lengths in hair sculpting?

Perpendicular distribution is utilized to create uniform lengths in hair sculpting because it involves lifting the hair straight out from the head at a 90-degree angle. This technique ensures that each section of hair is cut to the same length, resulting in a uniform shape and balance throughout the hairstyle. This method is essential in creating blunt cuts or layered styles where consistency in length is critical. By keeping the hair perpendicular to the section being cut, the stylist can achieve precise and controlled results, ensuring the desired look is maintained across the entire head of hair.

Other techniques, such as over-directional or diagonal distributions, are more focused on creating movement, texture, or angles rather than ensuring uniform lengths. Curved distribution also alters the shape by shaping the hair around a natural curvature, which does not serve the purpose of achieving straight, uniform lengths.
