The e3000 approach is pretty hard core. I can't say too much because I don't know exactly how they go about things but if someone has a particularly dense beard I don't think a complete clearance is probably the best approach. I'm not sure they do this in all cases so I may be speaking out of turn, I do have a special knack of putting my foot in my mouth sometimes. I've seen a few pictures myself and in one of them the person in the picture looked like she'd gone fifteen rounds with Mike Tyson.
http://jmcl.wordpress.com/tag/electrolysis/ (scroll down for the pic) Where follicles are tightly packed they should be thinned rather than cleared otherwise there isn't always enough undamaged tissue to effect proper healing. You're always going to get horror stories, true or not, but most issues with electrolysis resolve in time. I think the main thing is NEVER pick and give your skin a chance to heal itself, no special potions or creams that your electrologist doesn't recommend. Complete healing can take as long as a year, be patient and don't panic.
As for laser cutting your treatment time in half this isn't always strictly true and here's why. You're probably looking at 6 treatments minimum probably more like ten as they are often reluctant to frighten you off in the beginning by using enough energy. With treatments spaced 6 weeks apart this is minimum 36 weeks and after only six treatments you can be pretty certain there'll be a good few hairs left. If you do opt for ten or more treatments you're going to be looking at around 60 weeks and there will no doubt still be some hairs left. At this point if you start electrolysis you're going to be looking at a further year... possibly. It will take around this long for all of your follicles to cycle through and produce hair before they can be treated. It might be less but who can say for sure.... However! if you have the funds and start with electrolysis from the beginning you could be finished in around one year... ish. This might end up costing you more in the short term, then again it might not. One things for sure though it could well save you time and as I was told, "you can't earn more time"
You probably already know this but just in case you don't. Laser won't work on grey hair or blonde hair. I have seen someone say they are having success in spite of being a ginger.I don't think it works particularly well on red hair either. Ideally the hair should be dark and course and the skin light. I hear a combination of Alexandrite and Yag works best. I didn't have yag myself so I can't really comment on that. I think some people are a little more optomistic about their results than is realistic. From what I've experienced and from speaking to and corresponding with some of the top electrologists in the world, The general consensus is that laser will only take someone so far with beard removal before electrolysis is needed to finish off. Best of luck
