You will need to get a copy of The Blend Method by Mike Bono at the very least if you buy only one electrolysis book, that is the one to buy. We like others, but since they are expensive, you start with that one, and go from there. (Extra bonus points if you score a coveted first edition)
The machine will uses F-shank probes, which, depending on the company, will come in sizes ranging from 1 - 6. When ordering, you call them F-1, F-2, F-3, F-4, F-5, F-6. As you are working with minimal visual aide, you will probably have to go with an F-3 to split the difference between a probe that won’t bend as easy, won’t be too sparky, and will be easy for you to insert.
You should contact Texas Electrolysis Supply 1-800-626-6025 for probes, books, and any other supply, and service needs. They can even fix your machine if it needs it, and replace any worn or broken parts. (Probe holders, foot pedals.)
You should start with Galvanic and work your way up to blend.
The worse your insertion skill, and the lower your pain tolerance, the longer each hair will take to treat. As your skill increases, your treatment time and experience of pain will lower.
Finally, you REALLY, REALLY, REALLY, should get a partner and have the partner do the work on you, and you do the work on the partner, as self work is inferior to someone else working on you EVEN WHEN YOU BOTH ARE RANK AMATEURS!
