What is the primary function of a weight line in hair cutting?

The primary function of a weight line in hair cutting is to define a haircut’s overall style. The weight line represents the point at which hair volume is concentrated, which significantly impacts the shape and silhouette of the finished haircut. It serves as a guide for the stylist to maintain balance and structure throughout the cutting process. By creating a distinct weight line, hairstylists can establish a clear boundary between sections of hair, enabling them to manipulate the length, layering, and texture according to the desired style.

This concept is essential for achieving different looks, as the weight line can influence whether a haircut appears more blunt and geometric or soft and flowing. In contrast, options related to adding volume, determining hair texture, or indicating hair growth direction address different aspects of hair cutting and styling but are not the primary role of the weight line itself.
