haircut (n.)

also hair-cut, 1887, "act of cutting the hair," from hair (n.) + cut (n.). As "style of wearing the hair," by 1890.

The Romans began to cut the hair about A.U.C. 454, when Ticinius Maenas introduced Barbers from Sicily. Then they began to cut, curl, and perfume it. The glass was consulted as now upon rising from the barber's chair. [Rev. Thomas Dudley Fosbroke, "Encyclopædia of Antiquities," London, 1825]
