Yeah but I’ve interacted with it a lot and most of my interaction is commands sent through one of their programs. Versus scripts like init.d whose contents I can easily inspect and modify. Init scripts aren’t config files, they’re directly executable code.
Even then, a basic soap like Dr Bronners or your favorite “hand soap” does well for most of your body. People ask my wife how her hair is so amazing, she just washes it every couple days instead of every day and sometimes has some light argan oil or something to reduce frizz. Washing hair (especially long hair) every day damages it no matter what you’re doing. The most important thing is to scrub your scalp really good.
