I was still having DH and gastric issues after going gluten free and finally was told that it could be because of the shampoo, laundry detergent, soap etc. that I was using. I threw out all of my old stuff (actually gave it to my daughter) and started with only gluten free products. My issues went away and I have not had any problems since unless I accidentally use the wrong soap at my daughter's house etc. I have been told by a couple of GP's that it is no different from a nicotine patch or whatever, things are absorbed through the skin and into your body. I was recently told that the Mayo clinic disagrees with these doctors. They say it isn't possible. What do you think? Have you had a similar experience? Do you know of any clinical studies that show gluten can, in fact be absorbed through the skin?
