Thin, fine hair advice needed

Hi ladies and/or hair professionals, I need your help! I have thin, fine hair with almost no volume. It has been described as "every hairdresser's worst nightmare" 😂😭

I have a hairdresser appointment on Tuesday, so I'm looking for some low maintenance hairstyles for hair like mine! I am definitely going to shorten my hair cause I need to cut of split ends, and I'm open to shortening it more than what is absolutely needed, but I wouldn't go shorter than collarbone lenght.

It's important to me that it's low maintenance, cause I rarely have time/skills to do anything with it, I mostly let it air dry and I'm trying to avoid using heat on my hair.

+ I have an oval face with a tendency to look round because cheeks 😂

This is how my hair looks right now, so please post tips, suggestions, experiences 😊
