This begs the question...wouldn't you notice if you lost your hair?
It is not like that time recently that Britney Spears lost a big chunk of hair in the middle of her concert (although that probably hurt a heck of a lot more since hers is glued in), but still. You had a big mess of fake hair on your head. Later you don't. Seems to me you should notice.
Also, although it was kind of the person that found the hair to place it up on the metal thing I saw it on, in case the owner discovered she did, in fact, lose her hair, it was also kind of...GROSS.
Did they know it was hair when they picked it up? Does that make it any better? I think not.
Thoughts to ponder.
