When you shed enough hair to open a wig factory with every shampoo, you've gotta do something with all those extra strands. Many people stick this stray hair on the shower wall so it doesn't clog the drain, and this is the perfect canvas for creating hair doodles. The idea is that you'll clean up all the wall hair once you're out of the shower, but that never happens, does it?

Many people brush their teeth in the shower for the sake of multitasking. And as long as you do a thorough job, it looks like brushing your teeth in the shower is an OK practice, according to Southeast Family Dental.

Other than that, you can't beat the ease of gargling and rinsing under a shower nozzle.

You're just being super frugal, right? The same razor blade you've used for the past few months is still going strong. That is, if you exert a lot of pressure with every stroke.

Although most of these gross habits are harmless, old blades can pose an actual problem. Shaving with an old blade can lead to folliculitis, according to Prevention. Because those blades hang out in a damp environment, bacteria can grow on it pretty quickly. About 5 to 10 uses is all you can expect from the average disposable razor blade.

Have you been using the same washcloth or loofah for a few days or weeks? They aren't self-cleaning. In fact, washcloths and face towels should be laundered after every use to prevent bacterial growth, according to Buzzfeed. But how many people follow those guidelines?
