I read recently about how in Africa where they didn't have access to skilled surgeons, doctors would pack large open wounds with loads of sugar. It provides a healing and antibacterial environment for the wounds. It's has all kinds of effects on healing the wound site that even mainstream medicine will admit to, while leaving out the bioenergetic component of sugar giving energy to the cells/tissues to help it regenerate.
Ray Peat also mentioned a topical dextrose/sugar solution would be beneficial for the scalp and hair in a podcast with Danny Roddy. I can grab the excerpt if you want, I posted it here somewhere.
So yes, I think if you can deal with the mess of it, like you have a few hours every day where you could leave a solution of dextrose/sugar/honey, it would be very beneficial.
Glad you find that idea of the broad continuum of infection in tissues and hair interesting. I think it is a very possible cause of many if not most cases of hair loss that is too overlooked by people researching hair loss. It's not exactly easy to diagnose if you've got an occult infection of malassezia or some other type of fungus, or an infestation of demodex mites, either or which could be deep in the scalp and missed by a dermatologist/doctor.
