Body hair takes 6-12 months to really disappear, but breasts start growing quickly. Very quickly for the lucky ones. So removing chest hair is important, especially if it's thick like mine was. I found a Groupon and had the whole chest and stomach done in 6 appointments for $350. I'm planning to do my back next.
I'm taking the cautiously plan and meticulously execute method of transitioning. It doesn't work for everyone, but it's working for me. Though I have to admit that I am constantly tempted to say "screw it!" and just go full-time. But family concerns, job concerns, etc. I'd rather wait an extra 6 months and be able to transition well.
Having said that, I'm on a low dose of HRT, so my newfound mental stability is absolutely estrogen dependent. And I think this is the only reason I'm able to be more patient.
