A barber (from the Latin barba, "beard") is a person whose occupation is mainly to cut, dress, groom, style and shave males' hair. A barber's place of work is known as a "barber shop" or a "barber's".
In previous times, barbers also performed surgery and dentistry. Today, with the development of safety razors and the decreasing prevalence of beards, in American and Commonwealth cultures most barbers specialize in cutting men's hair. Many barbers may still deal with facial hair if requested.
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.
Different states in the US vary on their labor and licensing laws. For example, in Maryland, a cosmetologist cannot use a straight razor, strictly reserved for barbers. In contrast, in New Jersey both are regulated by the State Board of Cosmetology and there is no longer a legal difference in barbers and cosmetologists, as they are issued the same license and can practice both the art of straight razor shaving, colouring, other chemical work and haircutting if they choose.
In Australia, the official term for a barber is hairdresser; barber is only a popular title for men's hairdressers, although not as popular now as it was in the middle of the 20th century. Most would work in a hairdressing salon.
