I'm sorely lacking inspiration, and need fresh eyes! (and I'm a little bit overwhelmed looking at hair on Pinterest...)

I have an appointment on Saturday to get my hair cut and full-colored. I had planned on growing out the color, but have decided that I'm still too vain to accept grey hairs

I've always boxed dyed my hair, generally some shade of red. Lately it's been in the medium auburn range. It used to be blonde, but my roots tell me it's probably in the brown family now. This'll be the first time I can do something a little bit more interesting with it.

So...please ignore my almost makeup-less face, bathroom selfie, and eyebrows that are begging for help (appointment for them on Sat too!) and tell me what you would do to this hair if you were me! Pictures and welcome! (I don't want to lose much length, but I've just been...bored with it lately.)

(I work for the state, so it can't be a really wild color--when I'm old and retired I might go neon pink though!
