    TLDR Human hair affects millimeter radiowaves due to its keratin content.
    The study measured the specific density of human hairs, primarily composed of keratin, to determine the dielectric permeability of hairs based on the attenuation of millimeter radiowaves. It accounted for multiple reflections of waves at the boundary of the hair layer, providing insights into the interaction between radiowaves and hair.
