Having a nail brush on hand is essential for maintaining hygiene and cleanliness in nail services. The primary purpose of a nail brush is to thoroughly clean the nails, removing any dirt, debris, and product buildup before performing any aesthetic services. This step is crucial because clean nails create a healthier environment for treatments and enhance the overall appearance of the nails during application of polish or other services.

While other tools may be used for tasks like polishing or softening the skin, the nail brush specifically focuses on cleansing, which is foundational in providing safe and effective esthetic services. Properly cleaning the nails with a nail brush helps in preventing any cross-contamination or infection, ensuring that the service is performed on a clean slate.
