I looked that product up and it says " verified gluten free" but does not say who did that. Companies can send thier products to different universities to be tested for gluten. I usually just avoid things with obvious gluten ingredients.
Andalou hair products claim to be "certified Gluten-Free". Andalou claims endorsement/verification by Celiac.com. However, their products variously contain hydrolyzed barley protein and wheat germ (Triticum vulgare). Does Celiac.com have documentation of Andalou's gluten-free status at < 20 ppm? I had a bad reaction from using Andalou Lavender and Biotin Shampoo and Argan and Sweet Orange Styling Cream. I strongly suspect the presence of gluten and doubt that hydrolysis is complete enough to remove reactivity (if it were it would likely eliminate the benefit of these ingredients). The Andalou Customer Service Dept. has repeatedly refused me access to their certification process, which they claim is through the University of Nebraska. They have also refused to share their certification with the manager of the Health Food Store where these products are sold. As a gluten sensitive MD physician and PhD biochemist, I have a hard time believing that Andalou products containing barley and wheat are Gluten Free. After I used these products, my eyes teared, and I got a red scaly rash in skin next to my hair. Has anyone else had a problem with Andalou products?
Edit: found this on their site:
