"No more tears" shampoo not working

[Gilgamesh]

Yeah, shampoo strips some of your natural oils away, your scalp replenishes those oils, as it is pretty much constantly producing them anyway; that's kinda what a scalp does.

Then what's the purpose of using shampoo? Why not take the step and not have those natural oils stripped at all? What do you do that requires your hair to be shampood every day? Nothing. By the way, I realise shampoo doesn't just make your hair fall out over night. I never claimed it did. It's a long process.

As for only using soap and deodorant on special occasions, as well? I think you might want to read up on personal hygiene. Hot water alone is absolutely not enough to get you clean. Dirt, bacteria and fungus are really good at clinging to your skin. Water is just water. It's not going to remove all that crap from your skin. Soap on the other hand will. Those chemical engineers I told you about also work to make soap as effective as possible at getting that crap off your skin. Dirt will cling to soap way better than it will to your skin, it's like magic! Even the most basic soaps will do a fairly good job of drawing dirt away from your skin in a way water never could.

What's wrong with dirt and bacteria, exactly? Also, natural oils, which we all know are there for a reason, come off with that stuff. Fungus, sure, but how rare is that?
