My hair is very fine, straight, and slippery, and so normally when I put it up I end up re-doing it

Ditto. It is a nuisance. I suspect we both look like Hepburn in "The Lion in Winter". If you saw it, you must remember how her hair just sort of scatter-shot around her head. LOL

Fine hair is an abomination. Mine is like spider webs, always drifting across my face.
