I agree that the combination of galvanic and thermolysis modes, i.e, the so called 'blend' method, delivers a higher kill rate (60%) with less chance of scarring than pure flash thermolysis (25%), but it will end up costing about 2/3rd more ($18K vs $11K) and take longer, as well.
Flash vs. Blend
The use of blend electrolysis after the beard has been greatly thinned out by multiple laser treatments works best. Unfortunately, those of us with gray, blond, or red hair, or those with darker skin can't use laser. We have no choice except to go with electrolysis.
After four clearings with flash, my electrologist switches to blend to "clean up" the remaining hair.
Where the beard is particularly dense, there will be some roughening of the skin (pitting) depending on many factors that are hard to quantify.
Any pitting which does not heal all the way can often be corrected by fractional laser resurfacing of the skin once the beard is permanently removed.
Lasers are amazing!
