Which service does a cosmetologist NOT typically provide?

Cosmetologists are trained to provide a wide range of beauty services, which typically include haircuts, facials, and manicures. While a haircut and a facial fall directly within the traditional scope of cosmetology, nail services such as manicures are also commonly offered.

Nail extensions, however, are generally considered a specialized service that falls under the domain of nail technicians or manicurists. These professionals typically receive specific training in the techniques and materials used for nail enhancements, which may not be included in the broader training for cosmetologists. As a result, while some cosmetologists may choose to offer nail extension services if they have pursued additional training, it is not a standard service that all cosmetologists are trained to provide. Thus, the correct choice highlights a service that is not typically associated with the standard offerings of a cosmetologist.
