It's obviously for dark-haired girls only, but this method has saved me a fortune on hair lasering and the result is just as good.
Early on in my transitioning (even before hormones), I started using a Braun epilator on my facial hair. I paid with 20 minutes of redness, but then was okay for several days. That's a real low-cost alternative, but not permanent.
Then my partner (FtM, btw, registered as Alex40 here) bought me a home photoepilator (Babyliss, if I recall correctly). Then my routine changed to this: wait until light fuzz needed epilating, then strike them with the photoepilator (using suntan cream, of course), and only then pull them out. This burn-and-pull routine took me just two and a half winters (the machine's manual said "no strong sun after photoepilating", so summers were out), and I'm practically free of any unwanted facial hair now, only needing to pull-epilate the remaining two dozen individual hairs a couple of times a month. Not unlike any woman with a bit of a hair problem, really. The remaining few hairs are simply too light for the laser method to work anyway.
Hormones helped too, no doubt, but this one purchase of a home photoepilator has given me 15 months of "laser" sessions for free, and its price is equal to just three laser sessions at a clinic. The result is just as good and the pain is much, much less. Home comfort is also much better than walking out of the clinic with red face.
Just my 2 cents of experience.
Effects may be temporary. Hairs may grow back, just as dark, years later. Beware...
