What must be done for nail polish to adhere well?

• A. Apply a base coat
• B. Remove all traces of lotion or oil
• C. Use a UV lamp
• D. Choose a darker shade

Answer: (B)

For nail polish to adhere well, it is crucial to remove all traces of lotion or oil from the nails. This step is essential because any residue can create a barrier that prevents the polish from properly bonding to the nail surface. Nail polish requires a clean, dry surface to achieve optimal adhesion. If oils or lotions are present, they can lead to uneven application, chipping, or peeling of the polish. Removing these substances ensures that the polish can grip the natural nail effectively, resulting in a longer-lasting and more polished look.

While applying a base coat can also enhance the durability and finish of the nail polish, it is not as critical as ensuring there are no oils or lotions on the nails prior to applying any product. The use of a UV lamp is specific to UV gel polish, and choosing a particular shade does not affect adherence but rather the aesthetic outcome. Thus, focusing on a clean surface is a foundational step in achieving a successful nail polish application.
