Today we're going to demonstrate how to remove ridges from a nail. I'm going to use a four way file, it's got different grits on each side. I'm going to use one that's - if you look at the ridges, they're not too bad in hers, so I'm going to use the smoothest, what I'm going to do is just kind of just go over and make sure that - just give them a nice little rub down. Then I'm going to take a four way or three way buffer and I'm going to start with the gray side. And just go down on the nail. Go then to the green side. And then to the white. And if you look, there are no ridges and it's smooth and shiny. And the things to determine how much pressure you're going to remove the ridges in the nail, it's going to depend on the size of the ridge. So you might want to add a little more pressure 'cause she has like an artificial nail right on the edge there so I'm going to just give it a little more pressure and then you're going to feel over it, just to feel once you don't feel any more bumps, then you can start with your buffer, and continue until you've got it used all three sides. And it's smooth.
