Which type of services are regulated under Minnesota law?

The regulation of services under Minnesota law specifically pertains to the scope of practice defined for licensed cosmetologists. Among the choices provided, permanent waving and hair coloring are categorized under the services that fall within the ambit of cosmetology regulations. This means that practitioners performing these services must adhere to the rules and standards set forth by the Minnesota Board of Cosmetology.

The key aspect of this correct choice is that it deals with services that require specific training and licensure in cosmetology, ensuring that individuals are qualified to perform these tasks safely and effectively. This regulatory framework is essential for protecting public health and safety as these procedures involve chemical applications and potentially intricate techniques that can significantly impact a client's appearance and health if not performed properly.

Other service types, while they may also be regulated, often belong to different licensing categories or may not require the same level of supervision and formal training as those found in the cosmetology scope. For instance, services like facial treatments and massages tend to fall under esthetics or massage therapy regulations, while cosmetic tattooing, although regulated, is governed by specific rules related to body art licensing. Thus, the recognition of permanent waving and hair coloring aligns more closely with the established regulatory environment for cosmetology in Minnesota.
