Which type of hair is generally fine and unpigmented?

Vellus hair is typically fine, soft, and unpigmented, making it distinct from other types of hair. It is often referred to as "peach fuzz" and is found covering much of the human body, particularly in areas that do not have terminal or coarser hair. Unlike terminal hair, which is thicker and pigmented and is commonly found on the scalp, face, and body, vellus hair serves a more subtle function and is less noticeable to the eye.

Lanugo hair, although it is also fine, is primarily found on fetuses and is usually shed before birth. It is thicker and more downy in texture than vellus hair. Facial hair typically refers to the coarser, pigmented hair that develops during puberty in males, which contrasts with the fine nature of vellus hair. Understanding these distinctions is crucial in electrology as it aids in treating different hair types appropriately.
