Which term describes longer, coarser pigmented hair?

• A. Vellus hair
• B. Lanugo hair
• C. Terminal hair
• D. Pheomelanin hair

Answer: (C)

Longer, coarser pigmented hair is termed terminal hair. This type contrasts with vellus hair, which is fine, short, and lightly pigmented, and with lanugo, which is it’s fine fetal hair shed after birth. Terminal hair appears after puberty in areas like the scalp, eyebrows, armpits, and the pubic region, and it contains more pigment, making it darker and thicker. Because of its pigment, terminal hair responds best to laser energy, which targets melanin. A term like pheomelanin hair isn’t used to describe hair growth type; it refers to a pigment type rather than the hair’s length and coarseness.
