First of all, I doubt that all of the hair grew back. Laser treatments kill most of the active hairs in the treated area. What you were seeing is other hairs that are now becoming active.
As far as waxing, to have the most effective treatments, I would think that you shouldn’t wax at all. If you think you must, then you should wait a very minimum of six weeks before having another laser treatment. Otherwise, you are throwing money away. Relatively speaking, there won’t be very many hairs two that will be effectively treated two weeks after a wax job, even with fast growing hair.
If you have the need to throw money away, you could throw some my way. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" /> <img src="/ubbthreads/images/graemlins/cool.gif" alt="" /> <img src="/ubbthreads/images/graemlins/smirk.gif" alt="" /> <img src="/ubbthreads/images/graemlins/grin.gif" alt="" /> <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" /> <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />
