How permenant is laser hair removal with facial hair? Apparently electrolysis is the only true 'permenant'  hair removal solution. But seriously, I don't wanna deal with electrolysis. But I also don't want to deal with sudden surprise regrowth a few years down the track when I'm living as a woman. That'd be a nightmare. I don't see how facial hair can come back after the follicles have been destroyed and there's not enough testosterone to support facial hair. But I also don't want to guess and rely on that comforting faith. So, is it permenant, or could it come back? 
Also, is it true HRT (which I'm one month in to)  can cause the hair to go blonde and become unlaserable? I plan on lasering very, very soon but I don't want it to become unlaserable before my sessions are up. Thanks
