Brooke, interesting questions that I also thought about. We run a charity specifically for srs in Asia. The hair follicle issue, deep in the vagina, continies to baffle us. We have reached certain conclusions which I have raised in other posts on this subject.
We concluded that the inner vigina lining using scrotal skin or penile skin, that has been cut away to form the vagina, should not have electrolysis or lazer. This is today scraped and shaped in a special equipment, before being attached to the vigina opening. As Brooke stated above; tiny follicles, caused by incomplete hair removal, are difficult to scrape and esay to miss. Scraping is the still the best way to remove hair follicles, but the skin needs to be detached.
There is an area at the lower end of the vigina entrance that is not cut and can enter the vagina for up to an inch, especually in dilation. We recommend that electrolysis be done in that area, however, this can be done post op with a little more difficulty.
I never had hair removal and have no hair, this applies to my two western friends that had srs at the same time 2.5 yrs ago.
There remains a few of us that unfortunately suffer from hair in the vagina, it seems to be just bad luck. We as Eurasians and Asians tend to not be so hirsute and has not been an area of concern. I became first aware of the extent of the problem, in non Asian tgs, in this forum when I first joined.
