The opening paragraph is precisely why so many people have moved to natural ingredient products and fragrance free. Some fragrance makers have new for formulas with “clean” ingredients, but they are still proprietary and come with a “trust us” promise. It’s interesting to see the specifics of what these products can do other than what’s advertised on the tin.

My skin care routine is "I showered in some not-so-distant past" and sunscreen. You hit diminishing returns very quickly. Showering more than once a week has no health benefits, it's just so that other citizens of your overcrowded city wouldn't complain about your natural smell.

Not showering for a week means I have a headache all day. So evidently not everyone is doing it for someone else.

That doesn't sound normal? Why would you get headaches from not showering? Never heard of such a thing.

It's not terribly uncommon. My wife also has it. It's also related to the length of my hair, where longer hair is significantly worse. Presumably it's the oil build up as my hair is extremely oily and fine.

edit: I am fully aware that not washing leads to less oil build up over time, but I have tried and doctors have tried and that boat has sailed.

I'd imagine a hair wash in the sink also does the job when in a hurry then? Do dry shampoos work too, or does it need a wet wash?

Yes, washing the hair in any capacity works. Unsure about dry shampoo.

I see, that's interesting. Initially sounded like a hair weight issue, so by wet washing it you remove enough sebum to not drag on your scalp too hard. But I'm not sure it adds enough weight for it to do that.

I wonder that over time your scalp produces enough of some chemical to give you a headache, and so you need to rinse it away before that happens? Especially since you mention that any wet wash helps, so the chemicals in the shampoo aren't actually relevant for it. Interesting issue though, don't envy you.
