fine, short, lightly pigmented hairs covering most of the body
Vellus hairs, often referred to as "peach fuzz," are fine, short, and lightly pigmented hairs that cover most of the human body. Unlike terminal hairs, which are thicker and darker, vellus hairs play a role in thermoregulation and are typically less noticeable. They can be found in areas such as the face, arms, and back, and are more prominent in children and women.
