No - do not wax. Waxing removes the hair from the follicle. This makes it impossible for the electrologist to know which follicles are producing hair. Shaving is acceptable. Make sure you stop shaving a few days before your electrolysis treatment. The electrologist will need approximate 1 to 2 millimeters of length so the hair can be epilated.
Over time, repeated waxing can stimulate hair to grow coarser. It can also be the direct cause of ingrown hairs and in some cases, scarring. There are however some people that tweeze or wax for decades, and the hair growth is unaffected. It’s a real toss up. In my opinion, waxing/tweezing should be avoided due to the temporary and permanent side effects it can have on the hair and skin.
Before your electrolysis appointment you need to stop shaving for a few days or however long it takes for your hair to grow to 1 to 2 millimeters in length. Shaving has NO effect on progress.
