Sometimes, the way you file your nails makes a big difference in their long-term health if you file them too often. So, file them using the correct methods and your nails will stay stronger and more durable throughout your life.

It might be tempting to use a back and forth motion when filing your nails. It feels natural and seems more quick and efficient, but Cosmopolitan insists that's not the way to do it. Instead, use what they call a fluid motion, starting at one end, lifting the file as you move, finishing at the other end, and then repeating the motion until you have the nails you've been dreaming of.

"When you aggressively saw your nails with a file, it makes the tip frayed versus a clean cut," Madeline Poole, a Global Ambassador for Color at Sally Hansen told Cosmopolitan. "All of this is a gateway for peeling and premature breakage, since the harsh trauma of filing causes weakness."
