We have acids in our stomachs that changes the structure of hair.
Sorry, but you're incorrect. We cannot digest hair, as it's made of keratin. So, most likely enough of it swallowed would knot up somewhere in Gastrointestinal tract. I'm a med student btw.
Why don't you try?<br />
I doubt it as it is probably digested by the stomach acids. After that it is probably pushed through the intestines by the fibre.
