What Are Those Ugly Lines On My Fingernails?

Also, I may sound like I’ve been living under a rock or something, but I didn’t realize you could buff and polish them with a simple $8 tool that makes them smooth and shiny, almost as if you’re wearing clear nail polish. I found this shape and shine tool on Amazon, and now I feel like I have a brand new set of hands! This seems to be the quickest solution, just be sure not to get carried away with all that buffing and sanding, especially if you have thin nails.
Painting your nails will obviously help disguise your ridges as well, especially if you use a ridge filling base coat. It also helps create a bond with your nail polish so that it lasts a little longer.
