This is kind of going to be a shallow post. Sorry about that.

Anyway, it's time to re-dye my hair again - right now it's red, which as everyone knows is a color that fades quickly. And I'm sort of torn between dying it red again and dying it back to its natural color (partly because it's so expensive to have to dye it all the time). So I'm going to crowd source this one. This is my natural hair color:

and this is my current hair color - or pretty close to it anyway. It's a little faded right now.

So what do you think? Red or back to dark?

ETA: Thank you all so much for your help! It looks like the consensus is to go back to my natural color - which is great for my budget, anyway. So that will probably be what I end up doing, for now at least.
