15 minutes of electrolysis for me is $40. She's got over 2 decades of experience and is very fast and doesn't mark up my skin. It takes a couple of sessions to find the right settings, but once you do it picks up fast. I know other places are cheaper, but I've seen what electrolysis can do to your skin if they are not properly trained and experienced.
If you still have dark hairs... unless they are thinner than paper, you need to do more laser. I did not want to keep spending money on laser, but I ended up doing several full face laser treatments at the electrolysis center because she pointed out that it would be a lot quicker and a lot less painful to make sure everything we can get with laser, is gotten with laser. The place I originally got my laser done had in the contract 75% off for 4 years after, and when I switched to this new place, because of my past history of laser, she gave me her "maintenance price" which was basically the same exact cost. You have some freedom to negotiate with these places, especially if they're franchised versus a huge chain.
Waxing can cause permanent damage to the hair follicle that makes electrolysis less effective. Plus waxing is like renting and electrolysis builds equity :v
...I wish I could take an SRS loan out on the equity i've spent on transition...
I have lost count of how many times I have had my face lasered. The upper lip has been lasered something like 18 times and my full face/neck has been lasered like 14. There hasn't been much benefit on my throat for some time, but I do it anyway to make sure that anything that might spring up gets zapped. And it's actually barely more expensive to treat full face + neck than to do upper lip + sideburns alone.
Also, on electrolysis, one your dark hairs are mostly gone, letting the blond hairs grow out a little to get zapped doesn't seem to affect passing too much. Plus you could, for example, shave everything down and let the goatee area grow out for a couple of days (or up to a week or two if you've been on hormones a long time) and treat it section by section.
The thing for me now is that my hair grows so slowly that I have to wait a long time after shaving to see what is even growing, so planning an electrolysis appointment can take the better part of a month and I want to get as much done as possible before FT.
