Does this hair styling product exist?

A product that doesn't need to use heat to give my fine hair body?

We often go away, off-grid, in campervan and can't use a hairdryer. Is there anything I can do to give my hair some structure/style otherwise it will just sit clapped to my face.

I know this is out of stock, I usually get it from boots but can’t see it listed, but I spray this on my wet hair after a shower at night & leave it to dry. When I wake up in the morning my hair has lots of volume and tousled waves. They have several things in the range but I haven’t tried any others so can’t advise on those.

You could try a volumising powder - I like this one: here

You only need a tiny bit.

Mousse and hand scrunch while drying.

Batiste do a dry shampoo that has a plumping effect, quick squirt on the roots and rub in with your fingers should give you a bit of oomph

I use this. Make a world of difference and just brushes out.

Thanks all. Not looking for dry shampoo or wax as I need to put water in my hair daily (it's so fine). Thanks for all the other suggestions - the bumble one looks promising.
