Why does this always happen to my nose

So my nose is constantly dry and I always get scabs in, and on the edge of my nose (to the point where splits quite a bit). It always alternate between each nostril. Once one side fully heals after 3/4 weeks it move to the other side and wondering why the fuck it happens.

Any ideas?

For those who don't like seeing holes and looking up a nose. Ignore the photo loool
