Who may NOT perform cosmetology services?

The correct choice is that individuals with an inactive license may not perform cosmetology services. A cosmetology license needs to be active to legally provide services, as an inactive status means that the individual is not authorized to practice. This status can occur for various reasons, including failure to renew the license or if the individual has chosen to stop practicing temporarily.

In contrast, individuals with a temporary license are usually permitted to perform cosmetology services under specific guidelines as they work toward obtaining their full, active license. Students in training can also provide services, but typically under supervision as part of their educational program. Additionally, there is no age restriction that would disqualify licensees over the age of 65 from performing cosmetology services, as long as their license remains active. Therefore, having an inactive license is what specifically restricts individuals from legally engaging in cosmetology work.
