What should you always do before performing a nail application?

Before performing a nail application, ensuring that the workspace is clean is of utmost importance. A clean workspace helps maintain hygiene and prevents the transfer of bacteria and germs to the client's nails, which can cause infections or other complications. Additionally, a well-organized workspace allows for efficiency during the application process and promotes a professional atmosphere.

While applying lotion to the hands, choosing a nail polish color, or performing a manicure are all relevant steps in the nail application process, they do not prioritize the critical aspect of cleanliness which is fundamental to client safety and satisfaction. Cleanliness not only protects the client's health but also enhances the overall quality of the service provided.
