In the last month I went to two medspas for advice, though hormones aren't a part of my life yet. You may want to shop around and see what's in your area - both of them were in the local mall for me.
One used IPL, wanted $100 signing fee, $100 a month / 12 month contract for one treatment each month, plus additional services for $35-45 each (this included additional laser hair removal locations.) I had 6-10 treatments (6-10 months) suggested.
The other used a much more advanced process and the appointments would be calculated based off hair growth to kill the maximum amount of hairs per session. The lady here stated it would probably be a year and a half, with an effective warranty of 3 years I think for 2 additional treatments if I continued having hair growth (past 2, 75% off.) It was $1500 up front for the 5 treatments. Full body hair removal below neck, $12000 O.o
I'm going to go with the latter spa for my face because they use a better laser and because my moustache is getting increasingly blonde. It's very tempting to go with a year of IPL services on the rest of my body to thin it out/remove it while I figure out what kind of transition I want to do, though. Parts of me are just too difficult to keep shaved by a razor and it's miserable.
