What grit file should be used for filing eggshell nails?

Using a 240 grit file is appropriate for filing eggshell nails due to their delicate and fragile nature. Eggshell nails are thin and can be quite brittle, making them more susceptible to damage. A higher grit number, such as 240, indicates a finer abrasive surface, which allows for smooth shaping and finishing without compromising the integrity of the nail.

Finer grit files are designed to gently buff and polish the nail surface, providing a soft edge without causing breaks or splits commonly associated with lower grit files, which are more abrasive. This level of precision is necessary to maintain the health and appearance of eggshell nails, as they require extra care to avoid further weakening.

This consideration helps protect the natural nail while allowing for the desired shape and length to be achieved without unnecessary trauma to the nail structure.
