Does everyone at the Hair Salon have a license?

When you go to get your hair done are you sure that the person doing your hair has a license,do you even ask or look around to make sure? These days there are so many people working in hair salons without the proper licenses needed and required to perform services on the public. So how is this possible that unlicensed stylists can work in professional salons and not get caught by state board. Post your comments and thoughts on this subject.
