I got the following note from Jenny in May:
</font><blockquote><font size=“1” face=“Verdana, Helvetica, sans-serif”>quote:</font><hr /><font size=“2” face=“Verdana, Helvetica, sans-serif”> Is it true that the needle must be delivering a current to the follicle for 6 seconds for the blend method to be effective?
My friend who does electrolysis says the above is true and that for the galvanic method to be effective the current must be delivered for 19 seconds to kill each hair.
All I know is that I have spent a fortune on electrolysis over the last 25 years and not one practitioner inserted the needle for anywhere near 6 seconds, it was always 1 or 2 at the most.
Whatever is true the treatment has never worked and I basically feel really ripped off. No information is ever provided about how it should be done and there is no overseeing body to govern all those practitioners out there who are doing it wrong and ripping people off.
What is the truth in this matter and where can I find the right information </font><hr /></blockquote><font size=“2” face=“Verdana, Helvetica, sans-serif”>If you were getting thermolysis, the treatment time can be pretty short (especially with flash thermolysis). However, your friend is right if you’re getting blend done— it takes a little longer, especially on heavier hairs.
There are several variables that affect how long a hair needs to be treated. The prevalent working equation used by electrologists using galvanic and blend is the concept of “lye units.” In other words, it takes X units of lye to treat a given hair. As you might imagine, the thicker and deeper the hair, the more lye units are needed to kill it.
In his excellent book, electrologist Mike Bono categorizes hairs by the following units:
15 unit (fine vellus hairs)
30 unit (small terminal hairs on upper lip, face, arms)
45 unit (medium terminal hairs on face, chin, arm, stomach)
60 unit (large terminal hairs on chin, legs, back, shoulders, bikini)
80 unit (very coarse hairs on men’s beard and back)
Bono (1994) p. 143
So, the equation is: energy level x time = lye units.
If you want to treat a 60 unit hair at 0.3 milliamperes of power, it would take about 20 seconds with galvanic only. (3 x 20 seconds = 60 lye units)
The example your friend gave is based on a common standard that blend takes about one-third the time of galvanic alone, when at the same energy level. Below is a quote from Richards’ and Meharg’s authoritative book:
“For example, if you needed 18 seconds of galvanic current intensity at 0.4 milliamperes to remove hair using galvanic electrolysis alone, then you would need only 6 seconds (one-third of 18 seconds) of galvanic intensity current at 0.4 milliamperes in using the blend.”
Richards & Meharg (1991) p. 130
Unfortunately, finding a good electrologist is difficult in the U.S. as well. Regulations aren’t even in place in many states here. Your best bet is to go to someone recommended by a client who is done and happy. Easier said than done, I know!
