The Major Nail Filing Mistake You Might Be Making
What is the correct way to file your nails? You should always trim first and use the file for detailing. You should not use a file for shortening your natural nails. Trim with clippers for length, and file for shape. The sawing, back and forth motion is a no no for shaping your nails. You should file in one direction from the side of nail to the center of the nail with short strokes. Then alternate sides. And one to two swipes fully across for finishing the shape. But be mindful not to file the sides too much because the sides of the nails are stress points and if weakened it will cause breakage. Also, hold the file flat up against the nail when filing. If you angle to much it could thin your nail tip.
What’s the deal with files, anyway? Does it matter which one you use?
The rule of thumb for files is the higher the grit, the softer the file. So for natural nails a file grit of 240 or higher is best and for very thin weak nails a crystal file is best. Grits that are 180 or lower are intended for enhancements (acrylics and gels).
