TLDR Human hair has electromagnetic properties.
The study demonstrated for the first time the presence of inherent electromagnetic forces emanating from isolated human hairs. By using a solution with iron nanoparticles and Prussian Blue Stain, researchers observed magnetic lines of force and intermittent flashes of light from hair follicles, which caused iron particles to aggregate around the follicle. This finding suggested that human hair might have previously unrecognized electromagnetic properties.
