Hair half white half black, also known as "salt and pepper" hair, refers to a hair color that exhibits a mix of black and white strands. This distinctive appearance typically occurs due to the loss of melanin, the pigment responsible for hair color, as people age.
This hair color is often associated with aging, wisdom, and maturity. It can also be adopted as a fashion statement, with people dyeing their hair to achieve this look. Historically, salt and pepper hair has been documented in various cultures, from ancient Egypt to modern-day society.
