ARCHAEOLOGICAL AND CONTEMPORARY HUMAN HAIR COMPOSITION AND MORPHOLOGY

Contemporary and mummy hair samples are characterized and compared, using modern chemical and physical characterization methods. It is found that in cave conditions mummy hair can be preserved even if it interacts with environmental dirt or soil, X-ray diffraction and infrared spectroscopy results....
