thanks for your input, xeon and henry!

I think the height of my hairline is right. Like I said, I always had a high hairline.

I will ask John, which they take, the line or the edge.

About the density, I think a bit denser is better, because I'm still young. so maybe 65% ? Look at the pictures I posted in the beginning of this thread, to measure what density I need. If you need more photos, just ask.
