Structurally, hair consists of an inner cortex, comprising spindle-shaped cells, and an outer sheath, called the cuticle. Within each cortical cell are many fibrils, running parallel to the fibre axis, and between the fibrils is a softer material called the matrix. It grows from a hair follicle.
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.
