I have also been wanting to get laser hair removal done. I found a site that tells you what to look for and what to ask when you go for your consultation.
go to
www.elaserhairremoval.com/page_5.htm
Also, I have seen, I don't remember where, but apparently the pulse lasers are not as effective. I was trying to choose between a local place that does it and uses the Spa Touch system, a pulse laser and driving over 2 hours away to an actual Dr. that uses the Alexandria laser. As far as I was able to find the Spa Touch system, along with other pulse lasers are not "approved" by the FDA to be marketed as permenant hair removal, only as permanant hair "reduction" I did find a list of the ones approved to be marketed as permanant removal but of course where that was I don't know...... Do a search on Google for laser hair removal and I think it was on some kind of message board called Kitty's Consumer Beware.
I did go for a consutation locally and because of privacy issues they can't tell you their clients. You could ask them if they have clients willing to talk to you. I knew of someone (small town and all) who had gone for the more expensive one at the Dr's over 2 years ago and she told me that most everything is gone and still hasn't come back. Just a few stray hairs have appeared only.
Another thing, before you go for treatments make sure your hormones are under control. If you haven't taken care of them new hair will continue to grow until you do.
I hope this helps you.
