Many visually perceptible phenomena are observed in hair, which arise from intrinsic attributes as well as the orientation of fiber assembly. The use of image analysis to further understanding of hair properties is the focus of Roger McMullen contribution to Alluredbooks’ Practical Modern Hair Science, and in the following excerpt, he briefly turns his attention to that part of the body that bares perhaps more than a little semblance to hair: the eyelashes.

Previous studies demonstrate that skin buffering capacity can be measured in vitro by applying several concentrations of hydrogen chloride (HCl) and sodium hydroxide (NaOH) on skin and evaluating the pH change pre- and post-dosing. Here, the authors employed this technique to evaluate the buffering capacity of skin layers including intact SC, denuded SC and dermis skin samples.
