Me too, Denise! (pardonnez-moi, Eli!)
While sometimes I think I really should do something about my, umm, 'maturing' hair, I don't really want to start down that path of constant maintenance. Perhaps one day I'll see something in the mirror to help me overcome my laziness! In the meantime, I'm trying to be brave and natural.
As for artificial nails, they can be filed down more thinly at the cuticle end so that when they grow out there isn't such an abrupt demarcation line. Bring some polish, and fill in the gap (or not - whichever looks better) if necessary.
For natural or artificial nails, I've found that a polish with a little bit of frost in it helps to deflect the light and hide chipped/flaked places. Lighter colors are usually better, too. If your gloves or socks flake a bit of polish off of the tip of your nail and you're wearing a strong, matte red polish, that missing corner of 'red' will really stand out. You can use an emory board to lightly file the loose edges and just paint over the missing polish. That way, you don't need to mess with remover (or you can bring the saturated pads). Of course, clear polish is the easiest.
Remember to leave room in your 3-1-1 bag for that polish and/or hair color from home..I go to Wal-Mart and buy those teeny-sized bottles of nail polish; I like them OK for a trip, and they fit much better in that (stupid!) 3-1-1 bag.
