Some cruise missiles are able to do all those, like the tomahawk missile fe: https://www.naval-technology.com/projects/tomahawk-long-range-cruise-missile/
To me, this drone missile looks like a smaller, much cheaper version of the traditional cruise missile. Cheap to build (relatively), easy to transport, fast to launch, hard to intercept: scary times for Russia.
My scalp condition is that I have too much hair. Too dense and thick, it gets greasy after not washing it 1 day, so I don’t even dare to replicate your experiment.
I also used to have a cold weather dandruff problem, but that was solved entirely when I started always air drying after every shower. Thanks to a random tip years ago on reddit. My dandruff problem was apparently because of humidity.
