I have to disagree with one of your statements. A properly treated hair is killed the first time; you do not have to treat it "multiple times" to "weaken" it unless you're doing improper insertions or using insufficient current.
That may very well be true. The catch phrase is "properly treated hair". It's like saying a baseball player can bat 1000 with a proper swing of the bat. It doesn't happen. There are many variables that determine the kill rate, and although the skill of the practitioner is extremely important, it alone is not enough to achieve 100% kill.
There are approximately 30,000 hairs on the face. Using HF thermolysis (flash modality) a good electrologist can treat as many as 40 hairs a minute or 2,400 hairs an hour give or take. If all 30,000 hairs were in the growth phase (they're not, but for sake of argument) it would take 13 hours to treat every hair. If every hair was killed the first time, one could expect to be done with facial hair removal in 6 or 7 two hour sessions. I know of no one who can achieve that kind of productivity.
With 12-sec blend modality which has a higher kill rate than flash, a practitioner can treat 240 hairs an hour. If every hair was killed on first treatment, it would take 130 hours to be rid of all 30,000 hairs. And being that blend is less likely to cause dermal skin damage, that would a viable way to go, only no one can achieve that kind of productivity, and blend is typically used only after the beard has been substantially thinned out.
Every electrologist will tell you that it's so important to treat a follicle when the hair is in a weakened state because the kill rate goes up dramatically when the hair is immature. Electrologists often over promise the time it takes to complete facial hair removal because reality is hard to swallow.
And, another thing. Moisture content of the skin is even more important than the skill of the electrologist. One does not have to be an expert to treat a hair with blend (galvanic+RF), but the creation of the lye which kills the follicle depends on the presence of skin moisture. As the skin ages, moisture content diminishes and significantly reduces the kill rate which is why older patients take so much longer.
These are practical considerations that one should factor into their plans for facial hair removal if you hope to be successful. Ignore them at your own risk.
