Curly hair loves and needs moisture constantly. So using a spray like this just to wet your hair a little before applying a products of your choice is a great idea. It's handy and won't wet your hair too much (so you don't have to worry about water dripping down your neck while you're in that important morning meeting).
No time to air dry your curls? Using a diffuser can really help with that and it's safer for your hair. This one is detachable and you can buy the diffuser separately, but they work together so well that you may as well buy them as a set.
