Extra hair

My sister has extremely long hair. Although she likes it that way(in spite of the tangles) she'd be willing to get it cut for a good cause.
 So she researched Locks of Love. Somewhere along the way, she found that they only use 15% of the hair donated to them.
 Now, I'm not sure if this is true or not, but we were thinking- if they don't use that hair for wigs, then what do they do with it?
 Here is a sampling of our ideas:
-Soup
-Fake mustaches
-turn it into gelatin and make hair jello, then put it on the map of the Scandinavian peninsula
-Prosthetic toenails
-scarves
-throw it at people who they don't like
-put paint on it and then throw it at people who they don't like
-make jello out of it, then throw it at people who they don't like
-just eat it

There were loads more, but as we were extremely hyper at the time most of them made even less sense than these.
