Filing nails is an essential part of any nail care routine. It helps to keep nails looking neat and tidy, and it can also help to prevent them from becoming weak and brittle.
There are many different ways to file nails, but the most common method is to use a nail file. Nail files come in a variety of shapes and sizes, so it is important to choose one that is right for your nails. If you have thin or weak nails, you should use a fine-grit file. If you have thick or strong nails, you can use a coarse-grit file.
