You can have a bad reaction with any of the modalities because they are related to practitioner skill. By her suggesting to do a 10 minute test patch, she is my kind of gal! Exactly what I do for my apprehensive clients! People need a lot of reassurance in these beginning stages. I’m proud of you for taking it slow and doing your research.
I suppose you can ask her if she has references and pictures. Some may take offense and others may not. I am thankful for clients that trust me from the get go, but I certainly understand the one with a more careful approach and try my best to embrace all their questions and ideas about how to proceed.
I did Microflash for years and had no adverse complaints. The biggest skill required for this modality is accurate insertions and making sure the current goes off deep in the follicle. No shallow insertions with too much energy!
It sounds like this electrologist knows her stuff, but if you psychologically need to proceed in baby steps, so be it. I have and have had a few ladies like this and they know that it will take longer to do the baby step strategy, but choose slow progression over faster progression. Once they calm down, they release the inner mustang or hummingbird within me.
Another thing I like about this electrologist is, she is willing to do blend if that is what you want. Sometimes, I will suggest that we do MicroFlash / PicoFlash on one side and blend on the other, that way my client can compare sensation and healing and then decide what they want. That might be a suggestion you can make to your electrologist, too. You are still paying her for her time, so it doesn’t matter how slow or fast she goes. I will admit that slow frustrates me, but it is not about me.
Hope this was helpful and good luck!
