Final answer:
Nail preparation and using a base coat are the procedures that must be performed for nail polish to adhere well.
Step-by-step explanation:
In order for nail polish to adhere well, a procedure that must be performed is called nail preparation. It involves cleaning the nails, removing any dirt or oil from the surface. This can be done by washing the hands with soap and water, making sure to lather the backs of the hands, between the fingers, and under the nails.
A clean nail surface will allow the polish to adhere better. It is important to remove any debris or microorganisms that may be present, as they can interfere with the adhesion of the polish.
Additionally, using a base coat before applying the nail polish can also help with adhesion. The base coat creates a smooth surface and provides a better grip for the polish.
