What characterizes terminal hair compared to vellus hair?

Terminal hair is characterized by its coarser texture compared to vellus hair. This means that terminal hair is typically thicker and has a more pronounced structure, making it more visible and prominent. These hairs are usually found in areas such as the scalp, underarms, and pubic regions, and they tend to grow longer than vellus hair.

Contrastingly, vellus hair is soft, fine, and often lighter in color, making it less noticeable. It serves as a form of body hair that covers most of the human body and is more abundant in areas such as the face and arms. The coarser texture of terminal hair, therefore, is a defining characteristic that distinguishes it from the finer and softer vellus hair.
