mature hairline shape

so i'm trying to work out what a typical shape is for a mature, non-balding hairline. is density more important than the actual shape of your hairline?

either way, i found these pics online.

the guy (no idea who he is) seems to have decent density, but a very high hairline. his shape of his hairline is quite concave. so is that mature, or past the mature shape?

oh for pity sake. i did it again. posted in the wrong forum. sorry again. don't know what's going on with me.
