What type of hair is fine and unpigmented?

  1. Terminal hair

  2. Vellus hair

  3. Lanugo hair

  4. Coarse hair

The correct answer is: Vellus hair

Vellus hair is the correct answer because it is a type of fine, short, light-colored, and barely noticeable hair found on the face, arms, and other parts of the body. Vellus hair is typically unpigmented and is different from terminal hair, which is thicker, darker, and more noticeable. Lanugo hair is the soft, fine hair that covers a fetus and is eventually replaced by vellus and terminal hair. Coarse hair, on the other hand, is thick and dark, making it more visible compared to vellus hair.
