When was the American Barber Association established?

The American Barber Association was established in 1910, making this the correct answer. This organization was created to represent the interests and promote the development of barbers across the United States. Since its inception, the association has played a significant role in advocating for professional standards, safety regulations, and the advancement of the barbering profession.

While options such as 1905, 1915, and 1920 reflect different pivotal moments in the history of barbering and associated movements, they do not represent the actual founding date of the American Barber Association. 1905 precedes the establishment of this key organization, and the years following it saw developments in the barbering field, but none specifically align with the formation of the American Barber Association.
