California Code, Business and Professions Code - BPC § 7349.1

It is an unfair business practice for any person, firm, or corporation who engages in a practice regulated under this chapter to use the traditional symbol known as the barber pole, which comprises a striped vertical cylinder with a ball on top, with the intent to mislead the public in any manner that would make the public believe that barbering was being practiced in, or that a licensed barber is employed in, an establishment that does not employ licensed barbers.
