I have been gluten free for four years , I still have DH outbreaks but they are not as extensive as they used to be. I do still wake up every nite with terrible itching which causes scratching to excess. The hot humid weather of summer makes it all the worse. My worst areas are buttocks and forearms. I have not had clear skin for at least 7 years. I figure this had been building for so many years that it will take many years to disappear. It does not seem to matter what I apply to my skin, nothing really helps. I have never taken dapsone.
