I think it's because the hairline is not natural enough and dye job with the photoshop. But he may be one of those rare guys that get a dominant look being bald and look average with a full head of hair. Hair makes a bigger difference to restore looks in a conventionally attractive person or certain face shapes, either way most girls want to see nice hair.
My friend was talking about Diego Lopez's hair and I did some research, seems like he had just under 4000 grafts with Couto, what a choice too for a surgeon. So natural.

I think you'll grey late like me as you have almost none now, but provided you maintain your hairstyle and youthfulness, you can look good either way, the man is a model in the vid i've linked but goes to show it's just a colour . Also greying late means you don't have to dye it early (if you go down that route) which prevents dye related hair damage spanning decades.
I'd still recommend colouring up to 50 with a good hairline and younger face, before switching over to a salt and pepper dye for a natural Clooney look,
