I was thinking it would be a good idea to chop it up a bit with a 
sharp knife, mix it with topsoil and cover with about a half inch of 
gravel.  That ought to keep it out of impeller shafts, etc.

Hair does indeed breakdown.  If it didn't, we would all be up to our 
ears in hair as well as feathers, which are made of the same protein, 
keratin.  In fact, a good part of the world's available carbon supply 
would wind up locked in keratin if it didn't breakdown.
