What is the purpose of a guideline in hair cutting?

The purpose of a guideline in hair cutting is to determine the length of the cut. Guidelines serve as reference points that stylists can follow to ensure consistency and precision throughout the haircut. By establishing a predetermined length with a guideline, the stylist can achieve an even and uniform look, which is essential for creating balanced hairstyles. Guidelines help in shaping the style, and they enable the stylist to visualize how the hair will fall once cut, which is crucial in achieving the desired effect.

While creating volume, sectioning hair, and styling are important aspects of the haircutting process, they are not the primary function of a guideline. The guideline specifically focuses on the length and shape of the cut, providing a foundation for the entire styling process.
