IRON, COPPER AND ASH CONTENT OF HUMAN HAIR OF DIFFERENT COLORS

[摘要] Red hair contains more Fe than hair of any other shade. The presence of an Fe pigment in red hair does not account for the whole difference. It is assumed that in the hair Fe is split off from the organic pigment complex. No relation between the Cu content and the color shade of human hair could be found. The ash content of red hair is significantly higher than that of hair of other colors.
