Beardline no longer discernable Close-up of the kind of hairs that grow after time. You want to keep fine vellous hairs if they don't get too long. Sadly, much of it for me was on the upper lip. 200 hours plus for me. If you get through a dozen or so hours of electrolysis, especially with a few hours logged under the nose, and you are bummed when you have to miss an appointment, then you know you've got a bad case of gender dysphoria.
Some people say electrolysis is essential for passing.
For many, and myself, it is true. But I've met several T folk who I thought they'd had electrolysis and they haven't. They still have to shave, but their skin looks good. It's different for everyone. But I'd venture to guess that most people need it badly.
