Final answer:
A perm begins by sectioning the hair into panels. The size, shape, and direction of the panels vary based on the type of wrapping pattern and the type and size of the tool being used. Different wrapping patterns and panel sizes result in different curl patterns.
Step-by-step explanation:
A perm begins by C. sectioning the hair into panels. This is the first step in the process of applying a permanent hairstyle using chemical means. Sectioning the hair into panels ensures that the chemical reaction is distributed evenly throughout the hair for a consistent and desired outcome.
The size, shape, and direction of the panels vary based on the type of wrapping pattern and the type and size of the tool being used. Different wrapping patterns can create different curl patterns, and the size and shape of the panels determine the size and shape of the curls or waves produced by the perm.
For example, smaller and tighter panels will result in smaller and tighter curls, while larger and looser panels will produce larger and looser curls. The direction in which the hair is wrapped also plays a role in the final outcome, as it can create curls that cascade downward or sweep in different directions.
