Barbershops were influential at the turn of the 19th century in the United States as African American businesses that helped to develop African American culture and economy. According to Trudier Harris, “In addition to its status as a gathering place, the black barbershop also functioned as a complicated and often contradictory microcosm of the larger world. It is an environment that can bolster egos and be supportive as well as a place where phony men can be destroyed, or at least highly shamed, from participation in verbal contests and other contests of skill. It is a retreat, a haven, an escape from nagging wives and the cares of the world. It is a place where men can be men. It is a place, in contrast to Gordone’s bar, to be somebody.” 
In 1893, A. B. Moler of Chicago, established a school for barbers. This was the first institution of its kind in the world, and its success was apparent from its very start. It stood for higher education in the ranks, and the parent school was rapidly followed by branches in nearly every principal city of the United States. In the beginning of barber schools, only the practical work of shaving, hair-cutting, facial treatments, etc., was taught as neither the public nor the profession were ready to accept scientific treatments of hair, skin and scalp. Not until about 1920 was much effort made to professionalize the work.
In the early 1900s an alternative word for barber, “chirotonsor”, came into use in the USA.
The barber Sam Mature, whose interview with Studs Terkel was published in Terkel’s 1974 book Working, says “A man used to get a haircut every couple weeks. Now he waits a month or two, some of ’em even longer than that. A lot of people would get manicured and fixed up every week. Most of these people retired, moved away, or passed away. It’s all on account of long hair. You take old-timers, they wanted to look neat, to be presentable. Now people don’t seem to care too much.”
Despite the economic recession in 2008, the barber shop industry has seen continued positive growth.
Training to be a barber is achieved through various means around the world. In the USA, barber training is carried out at “Barber Schools”.
