<<Disclaimer: Verify this information before applying it to your situation.>> Altho I received several responses from people who said "what a good question--let me know what you find out", no one reported checking RECENTLY with manufacturers as to whether their products are gf. You may remember from the original post that I had a gluten reaction to Hydriesence, a product I had used for a long time. My hairstylist had stated that manufactuers frequently change their formulas. So I guess the moral of the story is that, we must frequently check with the manufactuers to make sure they are safe. If the formula has changed, there must be some sort of an indication on the label [such as the "use by" date] to help us. In the meantime, I guess I'll complete the Judi Densch look with not only the short hair, but the graying locks. Ann
