Aussie and Herbal Essences are both owned by the same company, so the response I got from them was the same I'd received for Herbal Essences ... that they sometimes use animal products but cannot indicate exactly when.
Thank you for contacting Aussie.
All of our products may or may not contain animal by-products, depending on what ingredient source was available at the time of manufacture. The ingredients used may be derived from a variety of vegetable sources or animal sources (typically beef or pork). I
ngredients that may be derived from animals are fatty alcohols, fragrance, gelatin, glycerin, hydrolyzed collagen, keratin amino acids, and tallow glycerides. Clairol/P&G uses vegetable sources whenever possible!
