YouTube Shaving Channels

Nobody seems to have mentioned Luca Dinaro. He posts several videos per week and has over 10k subscribers. His videos last about 30 minutes. 80% of his razors are straights and he is very passionate and skilled.
The catch is he speaks Italian! However if you cut to the chase and watch the shave you can learn from him.
There are several other very skilled Italians that make YouTube videos. Just google them.
Maybe check out Mauro Di Lernia, Nonsolorasatura and Mastro Livi Scuola teaches how to use and care for straights but again in Italian. But he provided translations from supertitles.

Used to have that entire list subscribed but the list is reduced to about half now.
Dagwoodz Tonsorium is a good one. I find he brings attention to some lesser known products as well as the usual suspects.
I also, always watch Eric from the WCS Daily shave line up. Definitely on my top 3 alongside Ruds and Michael Freedburg. Eric gets right into the details of the soaps and gear that's in use. As well as the artisan's history. Very informative, well spoken and great camera presence. Highly recommend.

I don't really watch any wet shaving videos anymore, per se..I mostly watch videos where a professional barber is giving shaves:
