At the time, I had a pretty old hair dryer that 'died' on me in the middle of using it. From then I air dry my hair (which is good for the hair anyway) until I bought myself a new one. But one time I needed a dryer real bad since it will quickly dry my hair than waiting for an hour for it to dry.
My brother let me borrowed his own hair dryer. It was Conair Lightweight Ion Dryer. The dryer were indeed lightweight, had two different setting to place heat either high or low, a off button in the middle and a nice sized cool button to press (above the 'low switch).
I'd put the hair dryer on high and in no time, it started to dry out my hair in less than two minutes. But since my hair is shorter, it took no more than a minute and if it can do that, just think of what it can do with a person with longer hair.
The dryer also has a removable filter in the back you can clean out for endurance. The Conair Hairdryer is pretty good quality at its price. And if you want dry hair in a matter of no time, choose Conair.
