A DIY blowout can be one serious arm workout, so make it easier and faster however you can. "You'll never get your hair dry if the bathroom is still steamy and humid from your shower, so go somewhere cooler," advises Mena.
A heat-protecting styling spray makes hair more pliable and prevents it from getting scorched.
While dividing the hair into at least four sections -- the top, the back, and one on each side -- can be time-consuming, experts agree that doing so practically guarantees a perfect blow-dry.
Ever wonder what to do with the blow-dryer's nozzle attachment? De Berardinis wouldn't straighten hair without it. Other musts: high heat and a round or paddle brush.
"Roll the brush inward once and then outward to get that sexy, glamorous S-curve around your face," says De Berardinis.
