So, if you are sensitive to gluten & wheat (not actually Celiac) then things like soap & shampoo & laundry detergent - can they bother you also? I do not have any itching scalp but am just not wanting to do anything that could aggravate any sensitivities. I use only things that have no laurel sulfates & no additives. I'd never heard that cleansing products could be a problem. Interesting.
