Quizplus · Accepted Answer

The delicate unpigmented hairs that cover the fetus in early development are called lanugo hairs. Terminal hairs are thick, long, and pigmented hairs that grow on the scalp, face, armpits, and genital region. Primary hairs refer to the first hair that appears on a developing fetus. Vellus hairs are very fine, short, and unpigmented hairs that cover most of the body. Secondary hairs are the hairs that replace vellus hairs during puberty, and they are thicker and usually pigmented.
