Which service is generally outside the scope of a barber's duties?

Makeup application is generally outside the scope of a barber's duties because barbers primarily focus on grooming and cutting hair, as well as facial hair grooming and shaving. The practice of makeup application typically falls under the purview of cosmetologists or makeup artists who are trained specifically in beauty techniques that involve applying makeup to the skin. Barbers usually do not receive training in this area, as their expertise is concentrated on hair and beard services rather than cosmetic applications.

In contrast, services such as men's haircuts, shaving, and facial hair grooming align closely with the traditional skill set of a barber, emphasizing their role as specialists in male grooming.
