I'm from the South West and I would usually say hair tie, but I use bobble too and would know what it means. I've had people be confused when I ask them for a hair tie before (mostly when I lived in the Midlands for university).

That's a bobby pin! And to me, a hair band is a u-shaped band that goes on the top of your head to push your hair back. I wear them all the time and usually call them Alice bands but I don't know where I got that from. Maybe it's an Alice in Wonderland reference?

I usually tie my hair up with scrunchies these days because I have ALL the hair and it needs special equipment, haha.
