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 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.
Also sex is a different thing from dating.
Also, the smell of sweat of someone attractive turns me on really hard.

some of us live in hot climates where a cold shower genuinely feels amazing and cools the body down.
some of us enjoy showering daily, because the bed sheets get less dirty that way, which means less laundry to do, and reduces my stress.
some of us are married to a lady and want a happy home life (lol).
a sample size of 1 (you) does not mean it’s true for everyone. Just saying. :)
I'm wondering if you have its informed consent.
