At Croda they use their TA.XTplus Texture Analyser to put hair tresses to the test. As an example, the effectiveness of personal care products on the physical characteristics of hair are assessed, with the bending force of a hair bundle used as an indicator of softness. Different types of hair are tested, comparing results before and after the application of various hair treatments.
For the test, the hair samples are divided into two bundles – one to undergo treatments, the second to be used as a control. An average bending force from a cycle of ten three-point-bend tests is calculated for each sample.
