well that’s good then. the one’s left aren’t anything to worry about, although i do know they look unsightly but that’s just one of the things you have to go through.
for future treatments, i would recommend that the doctor (or whoever does the treatment) shaves the area. ideally, it will be as close a shave as possible.
trimming isn’t enough. any part of the hair above the surface of the skin will be ‘fried’ and burn, there is absolutely no need for this, it doesn’t make the treatment more effective. all you end up with is that nasty burning smell.
