Electric hair, a phenomenon caused by triboelectric charging, occurs when hair stands on end due to the accumulation of charge. One example is the iconic image of Albert Einstein with his signature wild hair.
Electric hair is a topic of scientific interest due to its implications in understanding static electricity and hair dynamics. It has practical applications in fields such as hair styling and triboelectric energy harvesting. Researchers have traced the historical development of the scientific study of electric hair back to the 1700s.
