As a professional, it is your responsibility to ensure that your clients receive service in a safe and sanitary environment. In this course, you will learn the nature of various organisms, their relationship to disease, and how they can be prevented from spreading in the barber shop. It is important to realize that contagious diseases, skin infections, and blood poisoning, can be transmitted from one individual to another simply through the use of unsanitary tools and equipment. State boards and health departments require that sanitary measures and universal precautions be applied while Appearance Enhancement Professionals (AEP’s) provide service to the public.
