I ride every day. I've never made it 5 years with the same helmet. They eventually reach a point of stankyness that is irreversable. No amount of washing gets the smell out, they need a new face shield and the cost of new liners/shield is usually over $100... I'll just buy a new helmet at that point.
I currently have 2 Shoei RF1000's and a Shark Evoline 2 in the rotation
I think it usually pretty easy to identify the helmets that are worn out. Used... not for me thanks.
