Do we know what brands of shampoo that is vegan that you can find in your average drug store. Well, I have your answer here. I guess you are in the United States. Under normal big box chains "as Walgreen and CVS, you might get lucky with something that is accidentally vegan but for most it is a desert. I've never seen vegan friendly products to Wally World. Herbal Essence now contain animal ingredients and they also eliminated coverage regarding animal testing in their new packages. Tom Maine sometimes shows on the shelves large area, but it is not always there and since they were recently purchased by Colgate-Palmolive products will increased surveillance in the years to come. A brand that I had never expected to have vegan friendly options is Suave, but a couple of their products are accidentally vegan (but particular attention to the label for the strange chemical sources.). Are not there any health food stores around your area? If (like me) you are in the country you might consider web-orders to find good products. Another option is "long rod" with someone in the big towns and / or ask them to stop by a health food store for supplies. Since I often travel to "civilization," I am that for some people in my area.
