I mean a once a week shaver shouldn't have much voice but consider that I 99% of the time just use water for wetness.
Wetness is another important subject. That guy in the video spoke briefly about it but didn't really address it.
You obviously have an elf beard, not an orc beard like I have. Lots of differences. My beard is both heavy and coarse – lots of hairs – each hair is thick & coarse. When I was young and had a beard, it was black and heavy, like ZZ Top if they went undercover as rabbis. Now my beard is all white, still thick, but not quite as coarse as it was. It's like an Eastern European version of a Santa Claus beard, a Santa Clauswitz beard.
Wetness is the key to prepping those coarse beard hairs for a smooth shave. Wetness is also the key to being able to shave again the next morning without pain or blood. I noticed the video guy used a shaving brush, but only put shaving cream directly on it – dry – no added water. I first wash my face with soap, water, using
a natural boar bristle brush like this. It's stiff when dry, but softens in 5-10 seconds when wet. After scrubbing, I rinse off the soap with a wet wash cloth.
Next, I put some shaving cream on my hand and mix in hot water, enough water to thin the shaving cream, but not make it so thin that it runs down on my face. I cover my beard with the watered down shaving cream, and wait about 3 minutes.
The added water and the waiting time are both critical. It allows my beard hairs to absorb enough water to become noticeably softer as I shave. If I do this, the blade glides easily over my beard. If I skip the wait, my beard hairs tug on the blade, and I have to pull harder to shave.
I have found that it doesn't matter at all what brand of shaving cream I use, as long as I add water and give it enough time on my face before shaving. I also found that this wetting routine allows my razor blades stay sharp for significantly longer.
That's been my experience over many years of shaving. Wetting the beard hairs thoroughly matters more than the brand of shaving cream or razor. On everything else, YMMV. People will have their preferences for different fragrances in shaving cream, different types of razors or washing brushes, etc.
