.........She was using a paddle, what kind of electrolysis could that be? ......................and if the hair didn't want to come off she gave it a second zap. I didn't feel any tugging which was nice.
Good! No tugging. Second insertions are fine. If one has to go in more than three times, the recipe needs some tweaking perhaps?
Galvanic, Blend and Thermolysis can all be performed by using a foot switch or what you call, a "paddle". The foot switch enables the current to be delivered when the practitioner decides the insertion is perfect.
Most epilators come with an automatic timing mode, where no foot switch is needed. The practitioner sets it anywhere from .3 seconds to over 1 sec (on Dectro units) and then inserts before that time is up and the epilator releases the current at the designated time.
I do not use a foot switch. Depending on the difficulty of the hair project, I set the timer lower or higher, as needed. It allows me to sit more ergonomically comfortably and do longer sessions without much fatigue.
You are being served well with any modality of electrolysis whether a practitioner uses a switch foot or automatic timing. If they are not using a foot switch, you will be holding an indifferent electrode or something that will be touching you somewhere.
