#3 – File Your Nails
Try using a fine-grit cushion file to smooth out the tips of your nails. Avoid rough emery boards and metal-files as they act too hard on your finger-tips and weaken your nails. Always file in one-direction rather than treating them with a back-forth saw action. This too deteriorates the nails. Do not overuse nail-buffer as it thins and heats up your nails and makes them fragile and not just smooth and shiny.
