What determines.......

the length of time a hair needs to be zapped for and what strength setting the machine needs to be on?


It is not possible to give a good answer to that here. Your eyes would glaze over anyway. Let’s just say that the combination of the depth of the hair, and the thickness of both the hair and the anchor system join in with the sensitivity of the client/patient in conjunction with the capabilities of the electrologist and the equipment available to create a setting. All this can change each and every time a person gets treated, because of changing variables, for instance the client’s hydration factor. I have had to cancel appointments because my client was not drinking enough actual water to be a good candidate for safe electrology.
