A regular haircut, in Western fashion, is a men's and boys' hairstyle that has hair long enough to comb on top, a defined or deconstructed side part, and a short, semi-short, medium, long, or extra long back and sides. The style is also known by other names including taper cut, regular taper cut, side-part and standard haircut; as well as short back and sides, business-man cut and professional cut, subject to varying national, regional, and local interpretations of the specific taper for the back and sides.
