I would guess I was 10-15cm2 in the temples and and on the bridge behind the hairline. Things we discussed in my consultation was shockloss, at that time they (Shapiro, Matt) could do 20-25cm2 without having much shockloss. And I didnt have to shave my head. I am only guessing on my density. After I go back and talk with Shapiro I will have a better insight on my density. Yes Dr Rose did use the Tri-closure technique on me. you can see a line when I look way down, I tried to show that in one of my pics , but its hard to get it backwards looking down in the mirror, lol. from looking at me from behind you cant see the scar when i cut my hair to a number 3. I havent tried to go shorter because I am tall( 6'2) so I think the scar would be visable for most who look up at me. After the one year mark and I have documented my progress, I will let my hair grow out a bit and the scar wont show at all.
