Which of the following is considered an example of an unregulated service?

Ear piercing is considered an example of an unregulated service because it typically does not require a licensed professional or specific training in many states, including Minnesota. Unlike services such as esthetics or nail enhancements, which fall under the regulation of state boards and require specific licensure and adherence to strict hygiene and safety standards, ear piercing is often performed in a variety of settings—such as jewelry stores, malls, or even at home—where formal training may not be necessary.

This lack of regulation means that anyone can provide ear piercing services without needing to meet the same criteria that licensed professionals in other areas must adhere to. As a result, the potential variability in the quality of service and health safety practices can be higher in unregulated services like ear piercing.
