How do you put on hair extensions in short hair?

Adding extensions to short hair usually looks bad and is very uncomfortable as they typically have to be braided in VERY tightly. If you are wondering what it looks like, look at pics of Brittney Spears when she first got extensions after the whole head shaving debacle. They looked terrible, even though she clearly has a lot of money with which to get good extensions. Wait until your hair is a little longer if you really want to get them.
