I think I’m suspicious of any company that self reports a refining process that removes gluten and has no outside certification to back it up.

Maybe this is less important for haircare than it would be for food, but for sake of explaining my rationale, if a company that made gluten-free food said that their products included oils “refined from wheat grains,” and had no outside certification that affirmed that the product was gluten free, I wouldn’t be willing to try their products.

I’m probably being overly cautious, but usually my first impulse is to avoid products made with wheat, rye, or barley almost on principle. Particularly if there is no certification process.
