For me the big thing was my face. You can have hairy arms legs, tummy and live full time but not with a hairy face. Nothing gets one clocked faster than that. When I started I concentrated all of my electrolysis time on my face. Once I was full time and had my face to the point where I could keep it clear from session to session I then concentrated on the next areas. The area I am the happiest about having done was my armpits. With no underarm hair there is less sweat and less body odor as well.
I mean I did a lot of areas in my transition: face, eyebrows, underarms, back of my hands, forearms, belly (happy trail), bikini area, breasts. The hairs that personally bothered me the most were the ones on the breasts. The Hormones couldn't kill them fast enough and eventually I got sick of waiting and had them zapped. Having my eyebrows done means I only need to occasionally trim them to keep them nice and shaped.
All told I am guessing that I invested a good 300 at least hours in electrolysis, most of that being using the blend process on facial hairs. I am using that was maybe 70% of my electrolysis time. The last 30% was everything else.
Eventually with enough time the hormones do kill off the body hair, but my experience is that it's slow. What really killed everything off was after my SRS surgery. I think my body had one more growth spurt after surgery. These days I have 2 very small patches of hair on my lower legs that need shaving about once a month, and that's about it. The hair that does grow is pretty fine and probably wouldn't bother anyone but it bugs me.
For me electrolysis was easily one of the most expensive aspects of my own transition, only because it takes years and sometimes doesn't seem to ever end. Even the genital electrolysis took well over a year to compete and that required once a week visits in the beginning, and back in 2002 I was paying $100/hour for that time.
