Final answer:
For control during haircutting, hair is parted into sections, which aids in precision and symmetry of the cut. The hair shaft is comprised of three different zones: the cuticle, cortex, and medulla, each important for the hair's overall health and appearance.
Step-by-step explanation:
For control during haircutting, the hair is parted into working areas called sections. A hair shaft contains three zones: the outermost zone called the cuticle; the middle zone called the cortex, and the innermost zone called the medulla. When a hairstylist cuts hair, they divide the hair into sections to ensure precision and control over the cut, making it easier to manage and style.
This strategy is crucial for achieving the desired haircut and maintaining balance and symmetry.
Understanding the structure of a hair shaft is an essential aspect of hair care and styling.
Each zone has its unique properties, with the cuticle serving as the protective layer, the cortex determining strength, elasticity, and color, and the medulla being the innermost zone, though it may be absent in finer hair.
