Among humans, nature selected for little body hair as part of a set of adaptations including bipedal locomotion and an upright posture. Bipedal locomotion is extremely inefficient, and many animals can outrun human beings for short periods of time; such animals, however, are inefficient radiators of heat, and cannot run for long periods of time. Thus, human hunters must be able to chase animals for long periods of time, and must therefore have an efficient mechanism for radiating body heat. Upright posture, which exposes less surface area of the body to direct solar radiation, and subcutaneous sweat glands, which operate best with an absence of hair.
On 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.
The speed of growth is roughly 10 cm/yr = 0.3 mm/day = 3 nm/s. The cells at the base of the hair follicle divide and grow extremely rapidly. This is why people under chemotherapy sometimes lose their hair; the treatment targets any rapidly-dividing cell, not just the cancerous ones.
