My guess, absent a picture, is that your N3 accentuates anything that really exists but more than that creates for you a real focus point on the receding hairline--looking in the mirror it would be all you could see--but someone else probably wouldn't notice anything except that you're going bald.

I'm pretty much sure that this kinda headshape is what we're both dealing with:
