The best technique for filing your nails is to pass the file in one direction, from the left outside to the center, then from the outside right to the center, so as to smooth the scales of your nails.
At the end, if necessary, you can gently file the tip of the nail.
The ideal is to finish the care of your nails by applying a cream or an oil to nourish the nail and its cuticles.
Do not ever file your nails in a back and forth motion, it could traumatize the nail and lift the scales that compose it.
