What is a common cause of lifting in acrylic nails?

Inadequate preparation of the nail bed is a common cause of lifting in acrylic nails because the bond between the natural nail and the acrylic requires a clean, properly prepared surface for adhesion. If the nail bed isn't adequately cleansed of oils, moisture, or debris, the acrylic may not adhere effectively, leading to separation or lifting over time. The preparation process typically involves filing the nail to remove shine, cleaning it with a suitable cleanser, and sometimes applying a primer to enhance adhesion. Failing to perform these steps thoroughly can result in an unstable bond, making it more susceptible to lifting as external factors or daily activities put stress on the acrylic.
