Physical characterization of the hair of Mexican women
Hairs collected from 257 Mexican women, residing in Mexico City, were characterized by instrumental measurements for comparison to more‐commonly reported Caucasian, Asian and African hairs. Subjects were subdivided into five age groups and their hairs were characterized by fibre dimension, shape and tensile strength. Results show that Mexican hair appears to be intermediate of Asian and Caucasian hair in diameter and cross‐sectional ellipticity. Such findings seem in line with the early and late ethnic origins of Mexican people. Results also illustrate and confirm the large intra‐ and inter‐individual variability within any single hair property. Unexpectedly high levels of hair tensile damage were sometimes encountered.
