Individual Characteristics of Chemically Modified Human Hairs Revealed by Scanning Electron Microscopy
Hair that is treated with several different chemical reagents including those that are proteolytic, denaturing, or disulfide bond-reducing agents, undergoes structural alterations both internally and externally as revealed by scanning electron microscopic analysis. Some of these agents produce varying degrees of morphologic alterations in hairs obtained from different individuals. It would seem that this technique can be useful in the discrimination of human hairs from different individuals, since the chemically induced topological changes on the hair shaft apparently exhibit a high degree of intraindividual consistency.
