After hearing lots of good things about it here, and wanting great hair without having to go to the hairdressers (the Big Hair is loads cheaper!), I just bought it!
Had crap hair since I stopped BF 18m ago and can't stretch to regular cuts. Just thin and never looked nice. Went for the 42mm as I have shoulder length hair, layers and a side fringe, plus I want to grow my hair (but will still have payers etc). It's certainly big enough.
What heat protection do I need (though, after one use, it takes such little time and your hair is practically dry when you use it that it must get less heat than a normal hairdryer?)? Anything else?
