A tub shroom! Totally cheesy, as seen on TV product that actually works. I used to clog my shower drain completely every few months. The tub shroom has stopped that completely.

It is a bit gross cleaning it, at the end of my shower I remove the hair and rinse it free of shampoo etc and toss in trash.
