I am sorry to hear you are having these problems with airborne particle sensitivity. My initial symptoms were neurological (extreme fatigue and visual migraines) and dermatological. I had "eczema" from the base of my skull to my bra-line that itched and burned terribly. I do not have Celiac disease but I do have gluten intolerance. I have remained strictly gluten free for 6.5 years now (except for occ'l "glutenizing" by someone trying hard to be nice and feed me something they believe is gluten-free).
The first year I was gluten free I continued to have this rash in a smaller area but it would flare in the hairline. We found gluten free oats in a product we used and cutting out oats almost completely alleviated my skin reaction. My doctor informed me that the protein in oats is similar to other grains containing gluten so I may be reacting to it even though it is not actually gluten.
I now use only gluten free hair products as I have long hair and I figure that even though it is external hair blows in my face and I push it away or I may touch my hair to push it out of the way when eating or socializing. Everyone is different as far as items they tolerate but I have had good results with Griffin Remedy (available online at their website), Aura Cacia (although they do use Cetryl Alcohol which I used to try to avoid for other reasons), and Avalon Organics Cucumber gluten-free shampoo and conditioner. You probably already use gluten-free facial care products and lip glosses as you sound knowledgeable about Celiac and gluten-free issues.
I don't buy any of my gluten free products from a store where they are shelved with the regular baking products. (I would be OK with washing an item if it were plastic packaged but many are in cardboard so I personally feel the risk of contamination goes up). I am blessed to be married to a man who is open minded and glad to see me feeling better so there is nothing with gluten in our home (in food products). My diet is similar to the person who stated, "Solid advice" above.
Finally, if I am going out with friends I take food along with me except for a very few establishments where I am sure that I am safe. I also bring a bottle of water or iced tea, and even a napkin, as some people preparing food may be touching something with gluten and then handling glasses for beverages or setting tables without being fully aware (as was mentioned above pertaining to the gluten-free oats). I also found with the gluten-free diet fad that I have to be vigilant in asking about preparation in unknown venues (i.e. We were on a ski vacation and I was excited to see gluten-free items on the menu BUT the preparation area was not segregated, nor was the cookware. I was able to explain my needs and accommodations were made. Hopefully, the owner were more educated regarding the needs of people with gluten sensitivities vs. dietary preference and made some changes in their practices.)
I hope you find the piece to your puzzle that works for you!
