Which substance is used to ensure nails adhere properly with tips?

The substance used to ensure nails adhere properly with tips is an adhesive. In the context of nail enhancements, adhesives are specifically formulated to provide a strong bond between the natural nail and the artificial tip. They are crucial for maintaining the longevity of nail applications and prevent lifting or separation.

While base coats, nail primers, and top coats also play essential roles in the overall nail care and enhancement process, they serve different purposes. A base coat is applied as the first layer to protect the natural nail and improve the adhesion of polish. Nail primer is used to dehydrate and prepare the natural nail for enhancements, enhancing the adhesive's effectiveness. The top coat, applied after the color or enhancements, seals and protects the surface for a longer-lasting finish. However, when it comes to the primary function of bonding tips to the natural nail, adhesive is the correct choice.
