Comments P.S108 right column bottom paragraph: "Chemical composition and reactivity: The pattern of reactivity of hair is complex because it depends not only on the presence of reactive moieties in the fiber but also on their availability. The latter is significantly affected by fiber morphology and molecular structure. The bulk of hair is proteinaceous in nature, with the structural lipids and other materials representing only a minor fraction. The amino acid makeup of the protein components is given in Table I (primary source). Viewed from the perspective of biologic variability, dietary habits, sampling techniques, environmental effects, and diversity of texture, it is remarkable how uniformly the data cut across ethnic groups. Although there is considerable variation within each set of data, the ranges overlap and there are clearly no significant contrasts in the amino acid composition of hair of different ethnicity (primary source)."
