I have now completed my treatment.
I still have patches of hair in two places, albeit significantly reduced.
The leg hair has shown almost no reduction. When I first purchased treatments here I was told that their lasers worked on all hair types - even fine hair. Now that I am unsatisfied the managers (they seem to have several) are saying that the laser doesn't pick up fine hair very well. They're playing a completely different tune now that they've already got my money.
Not totally dissatisfied, but mostly. I would do some research and go elsewhere if I were starting this process again.
