What is the purpose of the base sections in perming?

The purpose of base sections in perming is to create subsections in larger panel sections. This is essential for achieving even and consistent results during the perming process. By dividing the hair into base sections, the stylist can ensure that each subsection is adequately processed, allowing for better control over the application of the perm solution and the placement of perm rods.

Base sections help in organizing the hair, making it easier to manage while applying chemicals, and facilitate uniform curls or waves by ensuring that the entire section of hair is treated equally. Additionally, proper subsectioning can aid in preventing tangling and allows for smoother installation of the perm rods, which is crucial for achieving the desired outcome of the hair texture.

The other options do not accurately reflect the purpose of base sections: chemically altering hair refers to the overall goal of the perming process, determining the direction of the perm rods is influenced by the stylist's technique rather than the base sections themselves, and preventing chemical change is not the function of base sections since they are utilized specifically to prepare hair for chemical treatment.
