I don’t like scented stuff either but mostly just cause it gives me a bad headache and/or migraine. Certain laundry detergents will make me itch too but I’m never really sure which one cause we use a lot of different ones. I usually just try to buy the natural allergy ones or whatever. Febreeze and bleach and that will make cough a lot but I get over it pretty fast. But I just avoid all scented stuff because of the headaches. Unfortunately, my parents sometimes forget and will spray febreeze or do nail polish in front of me or pour bleach or whatever. But if I’m fast enough and go get some fresh air, I’m fine and don’t get one.
