We normally associate hair loss, thinning and greying as markers of age, and a new study has now shown how ageing influences the diameter, surface topography, hardness, loss modulus, storage modulus, and tactile perception of human hair. A further understanding of the different properties of hair and the effects ageing can have can be useful to develop and evaluate better hair products and to advance the understanding of hair biology. In the study, carried out by the China University of Mining and Technology and published in the Journal of Cosmetic Science, research on the influence of ageing on hair properties was studied to enable a detailed understanding of the natural ageing process. The studies were carried out on three age group hair samples using a scanning electron microscope (SEM), a TriboIndenter and an artificial finger.
