Hairline
The edge where hair growth begins on the forehead, temples, around the ears and at the nape.
Also: front hairline
The hairline is the outline of the hair on the head. At the front it may be straight, rounded, M-shaped or come to a point called a widow's peak. Barbers sharpen it with clippers or a trimmer in a line-up, and stylists may shape it with a fringe or sweep it back. The fine hair right at the edge, sometimes called the edges or baby hair, is easily pulled by very tight styles, which is why braiders vary tension at the front.
