no we don't lose them everyday. if ya really want to know, the hair fibers are located inside the cochlea between the basilar membrane and the tectorial membrane, all of which make up a structure known as the organ of corti. When the BM vibrates to the frequency of teh sound it also moves the tectorial membrane which causes the fluid inbetween to stream across the tops of the hairs, which is then believed to cause the excitation of the inner hair cell that causes the action potential.
plus we only have like 3,500 hair cells with about 40 'hairs' each. if we lost them daily we'd sukc at teh hearing.
