Types of hairOn most adult humans there are two main types of hair: terminal hair, and vellus hair. A third type, lanugo hair, is present in the fetus, and some newborn babies. It can also be seen on the bodies of those who are extremely thin.
Terminal hair grows thick and long, and is what grows on the head, armpits and pubic area, as well as on the face, chest, arms and legs (better evident in men).
Vellus hair is a very soft and short hair that grows most places in the body in both sexes. In Caucasians it is often colourless, or blonde. It is best seen in women and children, as they have less terminal hair to obscure it.
