An oval cross-section is typical of this hair type

Explanation:
An oval cross-section makes the hair shaft non-round, so as the strand grows it has a natural tendency to bend, creating a wave rather than staying straight. Straight hair, in contrast, is typically round and stays smooth and upright. Extremely curly hair usually has a more flattened or ribbon-like cross-section that produces tighter curls, while wavy hair sits between straight and curly, displaying a gentle bend due to its oval cross-section. So the oval shape is characteristic of wavy hair.
