I am with you Mary, I have Stevens Johnsons Syndrome, this makes me allergic to lots of medication.
I can’t use certain wash powders and used fairy until I discovered I could use Bold Lavander and Camomile, for some reason it doesn’t react with my skin regardless of it being perfumed :?
Just lately I seem to be having to have lots of antihistamines as my breathing seems short at times and I get rashy hands.
Anyways, have you recently tried other wash powers? I didn’t used to be able to use bold but now with the lavender and camomile, I am fine. Just a thought.
