Is Hair Vegetarian?
AvoidNo. Animal product not typically used in food (more typically seen in medications, supplements, cosmetics and/or cleaning supplies).
Hair and the Vegetarian Diet
Hair, in the context of consumer goods, refers to the keratinous filament growing from the dermis of mammals. While not a food ingredient, hair is sometimes used in the production of non-food items such as certain medications, supplements, cosmetics, and cleaning supplies. Human hair, for example, is sometimes used in the production of L-cysteine, an amino acid that can be used in food processing, though it is not typically listed as an ingredient itself.
