What phrase must a barbershop display on its exterior?

A barbershop must include the word "barber" in its exterior signage to effectively communicate the specific nature of the services being offered. This requirement is rooted in the need for clarity and regulatory compliance regarding the type of establishment. The phrase helps potential clients immediately identify that it is a barbershop, distinguishing it from other types of hair care facilities, such as salons or beauty shops, which may not offer the traditional barbering services, including haircuts, shavings, and beard trims. By using the term "barber," the shop aligns with industry standards and regulations designed to protect both consumers and the profession. Thus, this terminology is essential in promoting the business accurately.
