Gluesticks

Is keratin in beauty products & glues for extensions really from bugs, &horns/claws of all kinds of animals?

Where do people get the keratin from so they can add it to glue sticks for weaving hair, and to put in cosmetics These for example ; http://shop.ebay.com/items/_W0QQ_nkwZkeratinQ20glueQ20sticksQ20forQ20hairQ20extensionsQQ_armrsZ1QQ_fromZQQ_mdoZ

1. Not from bugs. Their exoskeletons are chitin. There are not many things that can be done with the hoofs of animals slaughtered for food. Glue is a good use.
