2. Don’t Bite Your Nails
Make sure that you don’t bite your nails. A lot of people have a bad habit of biting their nails, and especially pulling out hangnails. But this is a bad idea when you have nail ridges for the same reason that it is a bad idea to keep your nails long – the ridges make for extremely thin spots within the nail where nails could easily crack or break wide open and that will make it a lot harder for your nail to heal.
You will have to wait for the entire fingernail to grow back in fact. If you have nail ridges, biting your nails can be one of the worst things that you can do. That’s also why trimming is so important. If your nails are trimmed, then you’re much less likely to bite them, even if you are in the habit of doing so. You can replace your biting habit with hard candy, toothpicks, or other oral stimulants.
