Which agency is responsible for investigating complaints against nail technicians in Minnesota?

The Minnesota Board of Cosmetology is the agency tasked with overseeing and regulating the practice of cosmetology, which includes the work performed by nail technicians. This Board is responsible for protecting public health and safety by ensuring that nail technicians adhere to state laws and regulations related to their practice. When there are complaints against nail technicians regarding hygiene, practices, or licensure, it is the Minnesota Board of Cosmetology that conducts the investigations to determine any violations and enforce appropriate action, such as disciplinary measures or further education.

In contrast, other agencies mentioned may have overlapping concerns but do not specifically focus on the regulation and investigation of cosmetology professionals. For instance, the Department of Health primarily focuses on public health issues at a broader level, while the Consumer Protection Agency deals with general consumer issues and financial fraud, not specific licensing disputes. The Department of Labor mainly addresses employment-related issues, not the professional regulation of cosmetologists or nail technicians. Therefore, the correct answer is rooted in the specific mandate of the Minnesota Board of Cosmetology to oversee and investigate matters pertaining directly to the practice of nail technicians.
