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.
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.
The diameter of a human hair ranges from about 18 µm to 180 µm. In people of European descent, blond hair and black hair are at the thinner end of the scale, while red hair is the thickest. The hair of people of African descent is typically thicker than the hair of other groups.
