What is considered a ‘cosmetology service’?

A 'cosmetology service' encompasses a wide range of services performed for compensation that involve the care and treatment of hair, skin, or nails. This definition is broad because the practice of cosmetology includes various specialties, such as hairstyling, skincare, makeup application, and nail services. The service must be performed by a licensed professional to be recognized under cosmetology laws.

The other choices are limited in scope. Focusing only on hair services or skin treatments excludes significant areas of cosmetology, such as nail care and aesthetic services. Additionally, services offered for free do not qualify as cosmetology services since the definition requires compensation for the service rendered. Thus, option B accurately reflects the comprehensive nature of cosmetology services as defined by legal standards.
