Hair function, the intricate role hair plays in human biology, encompasses its physiological and aesthetic attributes. For instance, scalp hair provides insulation, shields against harmful UV rays, and enhances sensory perception.
Hair function extends beyond mere protection. It contributes to self-expression, cultural identity, and thermoregulation. Historically, hairstyles have signified social status, religious beliefs, and geographical origin. Recent advancements in hair science have unveiled its potential in regenerative medicine, particularly in wound healing and tissue engineering.
