Structural Analysis of Human Hair Fibers Under the Ultra-High Voltage Electron Microscope

The study "Structural analysis of human hair fibers under the ultra-high voltage electron microscope" conducted three-dimensional analyses of human hair fibers using UHVEM and IMODE software, revealing detailed microstructural characteristics and differences between Japanese and Caucasian hair. Additionally, the document reviewed various hair care treatments, noting that antioxidants in sun care products slightly increased peak temperature but sometimes reduced tensile strength, silicones in hair dyes reduced color fading, and a new emollient enhanced hair shine. Arginine in hair coloring reduced oxidative damage, the Bradford assay was suggested for better quantifying hair protein loss, and new cationic polymers in shampoos showed superior conditioning. An improved delivery system for anti-dandruff active ingredients demonstrated enhanced effectiveness at lower concentrations.
