Biochemical variation of hair keratins in man and non‐human primates
Human hair from various racial groups was investigated using the following techniques: amino acid analysis, acrylamide gel electrophoresis, x‐ray diffraction studies, stress‐strain analysis. Each of these techniques yielded identical results for all samples, indicating that the variables producing phenotypic differences in human hair form are probably not on the level of primary or secondary biochemical structure. Hair samples of a variety of pri…
Quantitative hair form variation in seven populations
Although hair form has received much attention in the past, it has rarely been studied systematically, and never using direct curling variables. In the present study, seven groups were scored on eight variables, including four newly‐devised curling variables. These data were analyzed using univariate and multivariate techniques to give information about the population relations and mechanisms of hair form. “Racial” groups were separated using a p…
