It depends on your own personal reaction. Technically, the product must be ingested to affect you. Some people who get the dermatitis (can’t remember the term) opt to stay away from gluten in all forms, and some swear that topical application causes the dermatitis.

In short, it is a debated topic when it comes to personal care items. Use your own best judgment.
