70% alcohol is primarily used in salons as a disinfectant for tools such as nail files and buffers. It helps to kill bacteria and prevent the spread of infections. While styling hair and cleaning mirrors may also be tasks performed in salons, they do not require the use of 70% alcohol. Using alcohol to moisturize the skin may actually have the opposite effect, as it can dry out and irritate the skin. Therefore, disinfecting tools is the most appropriate use of 70% alcohol in salons.
