In modern times, the term “barber” is used both as a professional title and to refer to hairdressers who specialize in men’s hair. Historically, all hairdressers were considered barbers. In the 20th century, the profession of cosmetology branched off from barbering, and today hairdressers may be licensed as either barbers or cosmetologists. Barbers differ with respect to where they work, which services they are licensed to provide, and what name they use to refer to themselves. Part of this terminology difference depends on the regulations in a given location.
