I've only had two. I sterilized tweezers to pluck them out. One of them needed a sterilized sewing needle to poke and pull it out. To sterilize, just dip the tool in alcohol, peroxide, or boil it. Here's a link that has illustrations:

Try applying warm compresses to the area, this will draw the infection out and make it easier to remove the hair.
Try soaking a folded piece of tissue with hydrogen peroxide and covering the are with it. Chances are it will come to a head much quicker and drain itself.
