I live in switzerland, and we don't have here any specialised curly hair stylist.
They always cut the hair wet and style it straight

My hair is now at bra lenght, and I have 2c hair (I was 3a but with the keratin now I'm am 2c... Hoping it will revert back!)

I have a mix of normal and fine hair, and they are now cut with long layers: this has made my hair with no volume at all.

What kind of cut I should ask a stylist for have more volume?
Or I can cut them myself the deva way? (Anyone has a link with maybe instructions?)

Thank you so much!
