Are you sure that it wasn't an allergic reaction to something?
I guess it could have been. Anything is possible. Seems I'm having allergic reactions to medicines since going gluten-free. Never had a problem before..as for now, nothing new in my diet, soaps, detergents, shampoos, ect. Just trying to locate the source...I hate itching!
BZbee...my scalp was itching like crazy, too!
