The proper way to file your nail is not the back and forth movement that so many of us have done and were taught to do. No, all those great nail artists out there like Madeline Poole, who is Sally Hansen’s Nail Ambassador, will tell you the correct way to file your nail is to file in only one direction. Then lifting the file over your finger the other way and continuing to file your nails in the same direction then lifting back over your finger the opposite way in that motion. If you file back and forth you are more likely to create cracks and have breakage. You’re basically damaging your nail and making it more brittle instead of sharpening up your nail the way you want you’re hurting it. So remember NO MORE BACK AND FORTH MOVEMENTS!
