Layering hair involves cutting the hair in layers, which results in a graduated effect with shorter layers framing the face and longer layers in the back.
The ancient art originates from Japan as early as the 1400s, where layered hairstyles were the symbol of young women of marriageable age. Layered haircuts became popular around the world in the 1920s, thanks to the flappers who rebelled against the traditional long hairstyle.
