I bought a new house about a month ago. In the apartment that I moved from, I had a cheap rubber drain cover that seemed to work very well at preventing hair from getting into the drain, similar to this guy:

But the shower in my new house has a more permissive drain cover:

I'm pretty sure that more hair is going down the drain now than it was with the old solution, but hair still went down the drain with the old cover. I had a couple questions relating to this situation:
- How worried should I be about hair going down the drain?
- Should I replace the new drain cover, or add a secondary cover?
- Will I just have to resign myself to unclogging the drain periodically irrespective of drain cover configuration?
