Then, apply a small amount of nail glue to the area where the nail is loose and press the nail firmly into place. Once the nail is secure, you can use a nail file to smooth out any rough edges and apply a clear nail polish or top coat to seal the nail in place. If the nail continues to be loose or is causing discomfort, it's best to seek professional help from a nail technician or a dermatologist. **
