When I was in the bathroom light, 3 feet away from the mirror, I could see it. I had lowered my hair line 1/4 inch in the corners and brought the temples forwards. But when I stepped 6 feet back from the mirror and stood in the door way with a bit of shaddow over me, I could not even tell I had it on. Anyone thinking of hair transplant can play around with this and fingure out where to put their hairline. I'm doing it too so I'll know where to put it when HM comes out.
