Having spent hours and hours on both ends of the probe, I would have to say that Microflash is getting a bad rap from many practitioners who still insist that the only valid methods of permanent hair removal are galvanic and blend.
I am currently getting my upper lip and brows done and the method being used is strictly flash. I know from my own experience that Microflash is over-all at least as effective as the other two modalities, and if applied by a skilled operator, has a lot lower discomfort level than either galvanic or blend. I wish that my electrologist could provide the same level of comfort to me that I can give to my own clients!
One thing to consider here is that the newer machines ae much better designed and, operating 13.56MHz are much better at supplying heat than the epilators that were in use when Hinkle and Fontz authored “Galvanic, Thermolysis and the Blend”. The 27.12MHz machines are still more efficent at producing heat.
You mentioned that the frequencies used for thermolysis are not very efficent at producing heat in the follicle. However, when one considers that the average thermolysis machines, operating at the lower frequencies than those in current use, are still capable of producing thermolysis blowout, blanching and thermodessication, the question becomes one of how much heat actually needs to be produced to effectively destroy the regenerative tissues within the follicle?
Being a current consumer of electrolysis as well as a licensed practitioner, I prefer thermolysis to the other modalities as my electrologist can keep the areas that I am getting worked clear and I am seeing a constant decline in the number of hairs that are being treated to obtain each clearing. For this I am grateful.
I am getting to the point where my upper lip gets cleared and my electrologist can clear my brows and then move onto my chin in one hour now. This would not be possible in the 5 months that I have been having treatments with either blend or galvanic. They might be marginally better modalities as far as percentage of kill, but the speed of flash and microflash more than make up for the decrease in effectiveness, if any, when it gets evaluated on the basis of hairs killed per dollar.
Just my humble opinion,
Joanie
