The diameter of a human hair ranges from about 18 �m to 180 �m. 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.

Hair is a biological polymer; over 90% of its dry weight is made up of proteins called keratins. Under normal conditions, human hair contains around 10% water, which modifies its mechanical properties considerably. Hair proteins are held together by disulfide bonds, from the amino acid cysteine. These links are very robust; for example, virtually intact hair has been recovered from ancient Egyptian tombs. Different parts of the hair have different cysteine levels, leading to harder or softer material.

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.
