What are some ways to stop nail biting in teens?

Notice it: Often if you can notice that it is happening, you can stop these kinds of habits. However, some will paint their nails with jalapeno juice or some other vile taste to help remind you not to. The other thing you try is to carry nail clippers or files with you, as often it is the desire to clear a hangnail that starts it.

Look away: The more you "harp" at your teenager, the more they will do activity. Best approach is to ignore nail biting entirley and let their peers comment about it. This is a sure fire way to get an adolescent's attention. They don't listen to, their parents, but they do listen to their "friends.".
