Which type of hair typically lacks noticeable pigmentation?

Vellus hair is the type that typically lacks noticeable pigmentation. It is fine, soft, and usually lighter in color than terminal hair. This type of hair is found on most parts of the body, particularly in areas where terminal hair does not grow, such as the cheeks and forehead.

Vellus hair is often referred to as "peach fuzz" because of its light and delicate nature. The lack of pigmentation makes it less visible compared to other hair types. In contrast, terminal hair, which is coarser and thicker, usually has more pigmentation, giving it a darker or more vibrant appearance. Lanugo hair is the fine hair that covers a fetus in the womb but eventually falls out before or shortly after birth, and exogenous hair refers to hair that has been artificially added or extended, which generally retains pigmentation from its original source.
