Both laser and electrolysis hurt. I haven't had laser but electrolysis feels like your burning the roots one by one. Laser is faster and far cheaper than electrolysis but my hair was light enough and skin dark enough that had it existed, it probably wouldn't have worked for me.
When I transitioned, we need to have half our facial hair removed before we were given our letter for surgery. Along with RLE it was a test of our determination to become a female. Rather painful way to test our determination but they didn't understand us nearly as well as they do today.
