You really don’t want to use bulbous probes. That is why they are hard to impossible to find. They are not the best option. In my opinion you should stay with a good Ballet Gold probe’s polished and easy insertion needles in a size 5 or 6 if you can see well enough to insert them that big. If not, sizes 3 and 4 are fine.
In response to the above comment:
Ballet gold is a wonderful probe and I love using them and use them most often however sometimes I need to use other needle sizes and other needle types. For those who are interested in optimizing treatment, needle choice is one of those variables that can make a difference in terms of comfort and maximizing treatment efficacy.
There is no one formula. Indicating that using a 5 or 6 ballet gold as a blanket statement is limiting your options and isn’t going to be much help treating those finer upper lip hairs.
There are certain types of probes that are difficult to find and that in no way is an indicator that they are not worthwhile. For example: the copper probe is very hard to find yet it is my favorite to use when I am administering Multiple Needle Galvanic. Copper is a better conductor than stainless steel or gold.
Just because something is hard to find, doesn’t mean it isn’t worthwhile. Some things are very easy to find and are very bad for you. I can get a pack of cigarettes quite easily or even find easy access to junk food. Ah, but if I want to find some organic foods, I need to look around as they are not so easy to find.
I know the distress that comes from unwanted hair. If I were living in a time when permanent hair removal through electrolysis was not an option for me and circus show freaks could be gainfully and legally employed, I would earn my living as a beared lady.
Since electrology education is limited in most parts of the country, I suggest doing lots of reading: Hinkle, Bono, Schuster, Richards and Meharg have written good texts.
I always ask suppliers for needle samples, all types and all sizes. I test them all out as I set up controls changing one variable at a time and I take notes.
