This is a good, easy-to-understand overview of electrolysis for practitioners. There is not much of use for consumers, although you might want to make sure your electrologist has read it.
2002 update: Fino Gior has created a new site called electrolysisinformation.com. It has some useful information on treatment times and a good FAQ.
