How much scalp is removed...?

[VictimOfDHT]

That's it. I've made up my mind and I'm getting my 5th HT to fill in the thinning in my hair line and temples. I was really considering dr. Gho but the expense and the trouble involved (travel/travel expenses,the wait...) made me decide against going with him at this point and instead get it done locally (vancouver) by my last doctor.I was hoping to go FUE (or HST) to avoid more scarring but since I already have a scar I'm thinking what difference would it make? My only major concern, would this make my scalp too tight? I'm only getting around 600 grafts and I'm wondering how much of scalp (area) is that? I once read there are about 700 hairs (average) in one sq. inch on the head. I know the doctor isn't gonna take a square piece of scalp out of my head but a strip. Should I be worried or do you think it's too small a strip to be worried? This is like a never ending nightmare for me.
