Does eating steak, reverse hair loss?

I stumbled upon a video a month ago with over a million views where a doctor talks about how to regrow hair, and the main conclusion seems to be that eating steak will fix your hair, delivered with just enough half-truths to seem convincing. I’m not even a vegetarian, but this carnivore cult stuff is getting on my nerves. Is there anything to this claim?

Steak doesn’t reverse the genetics and the chemistry of hair loss. The internet is full of misinformation, that is clear.
