little information required

ive been waiting 18 months since starting the hormone replacement process for laser hair removal on the nhs. I am under the impression that i can get it done for free on the nhs being a pre op transsexual trying to pass as a woman but annoyingly for me i have to shave every 2-3 days.

now i did have an appointment once last year but i had changed address then the ex flat mate delivered my letter about an appointment to me just 30 mins before my appointment in a place that is almost an hour from me.

my questions are how long do the sessions take, is it painful and is there any special lotions or something i am to use after a treatment session?

Electrolysis or laser?
