My nails are really bad...mostly my thumbs.?

They have very deep ridges in them that you can see very prominently. This is mostly apparent on my thumbs. It also looks like a look a knife to one of them and made slits in the nail. Someone told me I may be low on iron, so I started taking iron pills but to no avail. Any suggestions of why this might be? It's not a pretty sight!
