I had a friend get laser on his neck and he never had to shave it again. I went to see about getting it done and my hair was too light-colored. You have to have darker colored hair for it to work - sorry blondes.

He said the procedure felt like someone snapping a rubber band on your skin, then like you had a sunburn for a few days. He had to do two or three sessions over a couple of months to get all the follicles.
