Hi...On many pictures here I see a dark line where the hair meets scalp. It almost looks like a line made with a marker. Is that from the way the piece is ventilated? Cuz on one side it will look completely natural and then on the other side you can notice the line. Is there anything that can be done to prevent or change that? I'm a little nervous about that cuz it looks a bit "different" from a natural hairline look.
Thoughts?
