Styling for dense, straight hair

I’m blursed with extremely dense hair. Every single hairdresser has commented on it saying I’m so lucky… but I absolutely despise it.

My hair just does not hold styles. Every time I get layers, they just wanna stay stick-straight. I have no volume, no texture, just a sheet of not-even-particularly-shiny straight hair.

I asked for a wolf cut, and I ended up with… bangs. And that’s it.

I’ve tried volumizing mousse with heat styling, heatless styling, hairspray, etc. I’ve heard sea salt spray could work, but I thought it was for curly hair?

Anyway, I’ll take literally any suggestions: hair cuts, products, treatments, whatever. Please. lol.
