Which of the following hair types is characterized as fine and short?

Vellus hair is characterized as fine, short, and lightly pigmented. This type of hair is typically found covering most of the human body, particularly in areas such as the face, arms, and legs. Unlike terminal hair, which is thicker and longer, vellus hair provides some insulation and can help with the detection of light touch.

Lanugo hair, on the other hand, refers to the soft, downy hair that covers a fetus in utero and is usually shed before or shortly after birth. Keratinized hair isn’t a specific type of hair but rather relates to the composition of hair, which is primarily made up of keratin, a protein. This does not specify the characteristics of the hair itself.

Thus, vellus hair is the correct choice as it aligns with the definition of being both fine and short.
