Yes, unfortunately Aussie is made by Procter & Gamble, a company notorious for animal testing. Luckily, there are plenty of awesome hair products made by companies that don't conduct useless, cruel animal experiments. I too started looking into cruelty free cosmetics recently, and I found Caring Consumer (the site linked below) to be a big help. They list which companies do and don't animal test.
Thanks for making a compassionate choice and feel free to e-mail me if you have any questions! :)
