My nails are suddenly starting to become rough on top. It use to be smooth. I'm wondering if it is some kind of deficiency? Does anybody know what the reason is and what can be done about it?

I've heard it's because you're not eating healthy enough. They have little filers that you can use on the top of your nail. I'm not sure what they're called, but they have a few parts to them that soften, shine etc. They've worked wonders for me. Your nails will be really, really smooth if you use em
