The complaint of hair loss may be related to an increased shedding rate or a decrease in the number of hairs per unit area (Rook and Dawber 1982). Apparent thinning of hair may relate to a decrease in hair numbers, in hair diameter or reduction of pigment. Microscopy or measurements will detect objective changes before the patient or physician is aware of any abnormality.
