The issue with having a beard is keeping it clean.
Food, toothpaste, bodily fluids, drinks.
Things just get in there. Some of it needs to be scrubbed out.
Toothpaste, for example. It foams up when you scrub. So it takes a bit to rinse it out of the beard.
Nobody warns you about blowing your nose, what that does to your mustache.
Spill some sugary cola on your beard and it feel like you need to scrub it for days if you dont get it all out right away..
If youre baking and get flour or worse, corn starch in your beard, gotta shake it all out before you clean it or else you risk making a rue.
Not fun.
