My theory -- and I'm fully aware that I may be propagating another myth here, but I don't think so -- is that the key to wet shaving is hydration. Hydration of the skin and, of course, hydration of the whiskers. Yes, lather lubricates, but what is also does is to ensure that millions of molecules of water are efficiently distributed across the area (skin and beard) to be shaved. And water, I submit, is what mainly makes the difference between hair removal and shaving with a blade.
Have you ever tried dry shaving -- no lather, no water, no nothing? I have. With a straight razor. Not my whole face (I'm not certifiably insane ), just a very small area. And you know what? A blade on dry skin cuts whiskers just fine. True, with lots of irritation, but hair removal takes place. Now if you add water to the equation (still no lather), things get better. Whiskers get shaved off, with less irritation. I *think* you could probably shave your entire face with water alone. It wouldn't be fun, but it would be doable, I think.
So, lather is the X factor that makes the difference between hair removal and shaving without irritation. Following the lead of William of Ockham, I submit that the least lather necessary to avoid irritation is all the "cushion" that's needed. How much is "the least"?
As William would say: YMMV
.....and there it is. Soap commander never gives me a thick lather, but the stuff is slick as hell. The more water I add to saponificio varesino the thicker it becomes, but it is still slick no matter how thick it gets.
