Barbers and cosmetologists may work in the same establishment provided that it is what type of shop?

The correct answer is that barbers and cosmetologists may work in the same establishment provided that it is a licensed dual shop. In many jurisdictions, dual shops are specifically defined as establishments that hold a license permitting both barbering and cosmetology services. This licensing ensures that the shop meets all regulatory requirements for both professions and allows for compliance with health and safety standards.

In contrast, while unisex shops and co-ed salons may cater to clients of all genders, they do not imply that both barbers and cosmetologists are licensed to operate in the same space. Mobile shops are primarily focused on providing services at various locations rather than being a specific type of establishment where the two professions can operate simultaneously. The key factor here is the licensing, which directly affects the legality of barbers and cosmetologists working together in the same location.
