Some lasers are superior to others. And here is the good news, I guess the new lasers are better at treating large areas and therefore cheaper. A woman in my area offers Gentlelase treatments on the stache for only 125 bucks per session!! GentleLase is supposed to be the best on the market now, but I heard there are going to be more effective lasers that cover larger areas in a shorter span of time, so the market does look promising. I want to get it done soon, but financially, I'm pretty broke. However, the people I know who have done the GentleLase have only told me good things. But this goes without saying, if your hormones are out of control and your IR isn't being treated well, then hair regrowth is likely to occur.
