What ingredients should I avoid in cosmetic products?

Gluten is only toxic to celiac patients and patients with dermatitis herpetiformis (DH) if ingested. Because gluten cannot be absorbed through the skin, the use of cosmetic and shampoos containing gluten has not been shown to be detrimental to patients with celiac disease or DH. However, we do recommend gluten-free lip products, hand lotions and other products that may end up near the mouth. And, in the case of children, a gluten-free shampoo would be wise.
