i'm actually very well read on the topic, and i apologize for not finding a more suitable. but i came here looking for razor suggestions, not to defend my diagnoses.
i am well aware that "gluten allergy" is a false term, which is why i didn't use it. perhaps mentioning my allergist made things confusing. it just so happens that my allergist (who i started seeing for asthma) is very knowledgable about celiac disease because he just happened to end up with numerous patients who have allergies (including wheat allergies, obviously) and comorbid celiac.
as for the "gluten molecule" and permeability, gluten is an incredibly bulky protein molecule (thousands of times larger than a small molecule like table salt, or even the average active pharmaceutical ingredient), which is actually a composite of two separate proteins (glutenin and gliadin). The entire gluten molecule need not be present to initiate a reaction, only the portions to which a specific individual is sensitive. (Not that anyone knows which portions those are and to which individuals.)
yes, i've been diagnosed with DH (yes, by actual medical doctors). i do also have allergies (which complicates the razor issue because once i found one with published ingredients, it was gluten-free but not lanolin-free, which is one of my allergens). i was hoping someone had experience with this (just as i've gotten help from others finding other health&beauty products in the past), so i could start with a much shorter list and then eliminate those with my known allergens. it sounds like others don't have experience with this, which is really all i needed to know. thanks.
