What does the term exterior refer to?

The term "exterior" refers specifically to the outer or external part of something. In the context of hair cutting, this can relate to the perimeter of a haircut or the outer layers of hair that frame the face and enhance the overall shape. Understanding the exterior is essential for creating styles that are balanced and proportionate, as it often dictates the initial visual impact of a haircut. By focusing on the exterior, stylists can enhance features, create movement, and achieve the desired aesthetic intended for the client.

The other options relate to components that are more focused on the inner structures or core aspects, which do not pertain to the outer look or finishing of a haircut. This distinction is crucial in hair design, where the exterior elements play a vital role in how the hairstyle is perceived.
