Recommendations please for a round hot brush good for volume and smoothing which I can use to dry wet hair but maybe also on dry ?
A little more of an investment but have you looked at the shark products?

I really rate the Dyson Airwrap. It comes at a price though

For something more affordable, I also really rate the Revlon hot brush
There are two I currently rate:
