There are no good 12v hair dryers. Heat requires power and 12v hair dryers simply don't produce enough heat to be any use. If you have enough battery power use a normal one with an inverter.
If you let us know what battery capacity & overall setup you have. If it's good enough you may be able to run a hair dryer via an inverter. Maybe at half power if possible. BUT half power is still about a 1000 watts as most hair dryers seem to be 1800 to 2000 watts.
Even only 1000 watts will suck the life out of your batteries very quickly. You need a good inverter, large battery capacity & also a substantial means of recharging. Even then one would need to be extremely disciplined to run equipment with heavy load for as minimum time as possible.
It's one thing running equipment, but then another thing getting that power back into the batteries.
You need to look at a whole system setup.
Not to forget payload. Large batteries, lots of solar & ancillary equipment. The weight adds up very quickly. Something somewhere has to give.

Robyn it's very hard for some of us, if not most of us to give too much info on hair dryers. Some of us haven't got a blade of hair on our noggins so hair dryers seem to be a long way down on our what to take list. Do hope you you can sort something out re hair dryer
