His bone structure is great to begin with. He looks alright bald imho, even if it hit him 10 years too early. He could pull it off.
I think these videos are indeed quite nice, they highlight the sometimes dramatic difference and the importance of hair.
To be honest though, they still look fake sometimes, esp in this video. Especially the hairline is too round and too thin. He even appears to have some sort of balding spot in the back. I look out for that stuff because if I part my hair like they did in the video, my cowlick is visible just like that and it's thinner in the video than my real hair. I mean you could it always by brushing it forward and then it did look convincing but with all these modern, upward styled dos, I'm not convinced. It's great though if you just want to have hair, sure.
