Yep, as others have said, he scrapes the follicles. 2+ years post-op and I have no hairs in my vagina (and still hair where I want it to be, because he's careful to put hair-bearing skin where cis women have hair, like on the far portion of the outer labia).
He also succeeds in getting more length than the original equipment necessarily has, as everyone I was there with got 5.5-6" despite some having donor material of less than 3". I hear he uses scrotal skin for a bit of extra if necessary, and he also saves the perineal skin that has to be removed anyway and adds it in as a graft.
I am not advocating for one surgeon over another, just reporting my own experience with Brassard - which is that I am fully sensate, orgasmic, adequate depth, and have had a gyno insist I was a cis woman who'd had a hysterectomy. I'm content.
