A haircut lineup is a technique used by barbers to define the edges of a haircut, particularly around the neck, sideburns, and hairline. It involves using clippers or a razor to create clean, sharp lines that enhance the overall shape and style of the haircut.
A lineup is an essential part of many popular haircuts, such as fades, tapers, and crew cuts. It helps to create a polished and professional look, and can also accentuate facial features. Additionally, a lineup can help to prevent hair from growing into the eyes or irritating the skin.
