Final answer:
Textured hair is defined as hair that has a tight curl pattern. This curl pattern is the defining characteristic distinguishing textured hair from straight or loosely wavy hair types.
Step-by-step explanation:
With regard to the wave pattern or configuration, textured hair is defined as hair with a tight curl pattern. This means that when we talk about textured hair, we are generally referring to hair that displays a distinct shape or pattern, where the strands form tight, curled shapes rather than being straight or loosely wavy.
Choices such as a very soft curl pattern, a smooth wave pattern, or an oily curl pattern do not accurately describe textured hair as much as a tight curl pattern does. Textured hair can vary from wavy to curly to coily, with the curl pattern being one of the defining characteristics that can add to its volume, shape, and overall aesthetics.
