Which of the following is classified as an unregulated service?

Hair braiding is classified as an unregulated service in Minnesota. This classification means that individuals providing hair braiding services are not required to be licensed under the state's cosmetology laws. The distinction stems from the nature of hair braiding itself, which is often considered a simple manipulation of the hair rather than a service that involves chemical processes or cutting, which would typically require formal training and licensure.

Unregulated services like hair braiding do not compromise client safety in the same manner as regulated procedures, where sanitation, health, and technical expertise are crucial. This allows practitioners of hair braiding some flexibility in service provision without formal state oversight. In contrast, services like hair coloring and facial treatments involve chemical applications and potentially more complex techniques that can significantly impact health and safety, thereby necessitating regulatory oversight and licensing to ensure practitioners meet certain professional standards.
