How to prep hair for bouncy blow dry?

[OrchidFlakes]

I’m trying overnight blow out rods and other bouncy blow dry styles (including round bush and hair dryer) but whatever I do drops quickly even after hairspray. Is there anything I should be prepping my hair with when it’s wet or any other time?

I’ve tried a few colour wow prep products (raise the root, carb infusion) with little success and mouse makes my hair super sticky.

any suggestions please?

The thing that works best for me is to blow dry your hair with your head down. Brush it down first and keep brushing throughout.
When dry just swing back upright, apply whatever product you want then finish off to style. Works for me and I have fine hair.
