Electrostatic and Dielectric Measurements for Hair Building Fibers from DC to Microwave Frequencies

The study investigated the electrostatic and dielectric properties of five different brands of hair building fibers, which were popular for creating a natural look for individuals with hair loss. The research employed DC and high-frequency microwave techniques to test these properties macroscopically. Additionally, a scanning electron microscope (SEM) was used to microscopically analyze the fiber structures, allowing for a comparison of the uniformity and breakage rates among the different samples. This analysis aimed to identify the distinct properties of each hair fiber brand.
