I know who that guy is from YT you're talking about. He's the "hairdresser reacts to..." guy. Oddly enough I don't watch him, but he does come across a lot in my recommendations. I watch this 50+ lady just livin' her best life who does beauty reviews who did a video that was her reaction to Brad M's video reaction to one of her videos!
Crazy! YT is so vast, I think it's kinda call we still all end up watching the same things. I too love cooking videos, my favorite is the Food Wishes guy.
