What type of hair is described as fine, unpigmented hair covering the body?

The term that describes fine, unpigmented hair covering the body is vellus hair. Vellus hair is typically short, soft, and barely noticeable, making it quite different from other types of hair found on the human body. It serves important functions, including helping to regulate temperature and providing a layer of insulation for the skin.

Vellus hair is predominantly found on areas such as the face, arms, and legs, and it appears more prominently in children, though adults also retain it, especially in less visible areas. This fine nature of vellus hair contributes to a softer appearance of the skin.

In contrast, terminal hair is thicker, darker, and often longer, developing in areas such as the scalp, eyebrows, and after puberty in other regions. Barba refers specifically to the facial hair of adult males, which is also terminal hair rather than fine vellus hair. Finally, lanugo is a type of hair that develops on fetuses, primarily in the womb, and is typically shed before or shortly after birth, making it different from the vellus hair present on the body after birth.
