is the professional a friend? If she's an electrolygist she will have their own equipment. The home and Pro units basically do the same thing, although the professoinals have equipment that can utilize several different methods of treatment, such as blend, which speed up the treatment process signinficantly. Home units like the One Touch are very slow compared to pro units. If you got a friend who can work on you for little to nothing, maybe just give em a tip, and save you a lot of money, because professional electrolysis is quite expensive, then go for it.
