Everyone hates getting a broken nail. It's a pain in the ass, and sometimes it's just pain! There are a number of products on the market the claim to fix broken nails. I have only tried one (Nailene Nail Glue), and it didn't fully live up to my expectations. Nailene Nail Glue (specifically for broken nails) works rather well however, if you pair it with a teabag. You can see a great tutorial on how to fix torn nails with a teabag here. She uses super glue, but I use Nailene Nail Glue instead. Super glue can be damaging to your nails and I advise you not to use it. I use Orly Top2 Bottom over the glue after it dries.
This method is extremely cheap, and also easy on your nails because teabags aren't made of chemicals like the other products out now-a-days.
