It seems like the loudest outcries are people afraid of others not washing their hands after using the toilet.
The article doesn't explicitly say anything about it, but I didn't get the impression that any of those people (even the ones that haven't showered in years) weren't washing their hands after going to the bathroom.
It's not pleasant, but if you gradually wash your hair less and less frequently the oils in your hair eventually find an equilibrium.
At least this is how it's turned out for me. I generally only wash my hair about once a week or less. At first it was crazy oily and frustrating, but gradually the amount of oil my head produced lessened.
