Allegedly, he purposely cuts his hair like that because he thinks of himself as a modern Augustus (Octavian).

He looks like he cuts it himself with nail trimmers.

Say what you want, but its also an iconic look. You recognize his face the moment you see it, with that sorta disinct (but still kinda shit looking) haircut.

But also I dunno, I can understand the vibe of wanting super short hair to keep it up and out of the way, some people just prefer their hair cut to stay the hell out of the way, without committing to being full shaved down.

I try not to judge on such a thing. If he likes that haircut, fuck it, the dude makes more money while sitting down for his haircut then 100 haircuts would cost him to pay for.

He can do whatever the fuck he wants with his hair.

I would rather judge him by his actions, like that shit he pulled with buying "private" beaches and whatnot.

Edit: Actually out of curiosity I looked this up for some updates, and it sounds like he and his wife have been putting in efforts to actually do right by the locals, and that a lot of the bad press was just trying to dunk on him and was largely just stuff going over poorly with locals, so he retracted offers and went back at it again but with the help of local professors to ensure he did it right and in a better way.

It sounds like over the past few years he and his wife have been pouring money, like a LOT of money, into preserving tonnes of wildlife and donating a bunch of money to save large areas that were going to be privately developed, and instead now have enough money to pretty much stay preserved and managed by the locals forever.

Not gonna lie, it actually sounds like the dude is trying to put in some real work to do good here, I have to say.
