Which of the following is NOT a typical characteristic of vellus hair?

Vellus hair is defined by several distinctive characteristics. One of the primary features of vellus hair is its fine texture. This type of hair is typically short and often light in color, which adds to its less noticeable appearance compared to terminal hair.

The correct answer identifies coarse structure as a characteristic that is not typical of vellus hair. Vellus hair is generally very thin and soft, lacking the coarse structure that is associated with terminal hair.

Understanding these characteristics helps differentiate vellus hair from other types of hair found on the body, such as terminal hair, which is thicker, longer, and darker. Recognizing these differences is crucial for anyone studying electrolysis, as they will be working with various hair types and must understand how to treat them effectively.
