Take it from a girl who's been using Electrolysis since she was 18, it's terrific! There are two ways to go. For smaller areas, a needle is used. It's inserted into the root of the hair where it zaps electricity into the "live" part of the hair. I know that sounds scary but it really isn't. It's not any worse than plucking, depilatory or shaving. This method hurts a little but over time you will get used to it. It only works well in small areas though. The second method is laser electrolysis which in my opinion is the best way to go. It's relatively painless and can cover a large area quicker than the needle method. A laser zaps the hair dead and a burst of cold air releases immediately so that you feel no pain from the heat of the laser. For really large areas (like the chest which you seemed to be interested in) you may need to go for a few sessions. It can get costly, but trust me it's worth the time and money. You won't have to worry about shaving, waxing, etc. And even if it doesn't permanently remove all the hair, it lightens it significantly. With the laser you will only have to do 3 full sessions, and then go back every 3-5 months for touch ups. (Better than daily shaving or weekly waxing IMHO).

Just some food for thought.
