Obvious things that can be manipulated to probably cause headaches: noise, stress, erratic sleep, physical exertion, dehydration*, allergies, altitude (obviously you’re not likely varying your altitude, and most people adjust to any reasonable <7000 ft level), reduction in caffeine, alcohol (and also sulfites in wine) - you’re probably considering the last two under ‘diet’.
[ * ] I guess I have personal experience nearly fainting from without-noticing-I’m-thirsty dehydration; never a severe headache I’d associate with dehydration without also enough exposure for a nice full body sunburn.
I don’t think it can plausibly be an environmental factor. It’s a lifelong problem and I’ve moved around a lot (also changed my sleep schedule plenty of times). My default consumption of caffeine and alcohol is zero.
I think scented cleaning products are common enough that people are likely to be exposed to them unless a deliberate effort is made to have everything unscented.
I don’t usually expose myself to cleaning products at all. When I do they’re usually just water. I spent a year and a half living in an apartment where neither my roommate nor I even owned a scented cleaning product. My laundry detergent is scent-free.
Okay, good luck then! You can try playing with subsets of environmental factors that may have been present across all those moves, but I’m not optimistic that you’ll have many interesting (and controllable) possibilities. Maybe you can find something that decreases your headaches’ frequency or severity even if they can’t be eliminated entirely.
None from personal experience, but I was thinking of Seth Roberts’ reports about migraine-sufferers identifying some triggers (e.g. fabric softener!)
