Which of the following services is not defined as part of esthetics?

The concept of esthetics primarily involves services that focus on enhancing the appearance and health of the skin, as well as overall beauty treatments. This includes services such as facial treatments, makeup application, and body wraps, all of which directly relate to skincare and beauty enhancement.

Hair styling, on the other hand, does not fall under the definition of esthetics. It is generally categorized as a separate domain within the salon industry that focuses on hair care, cutting, coloring, and styling. Therefore, choosing hair styling as the service that is not defined as part of esthetics is accurate, as it focuses on a different aspect of beauty and personal grooming that involves hair rather than skin.

Understanding the distinctions within the beauty industry helps salon managers allocate roles and services correctly, ensuring compliance with licensing and training requirements specific to esthetics and hair care.
