Personally, I think it depends on your hair. I know everyone here will read this and gasp, but a few years ago, i would dry my hair with a blow dryer on high heat with no all. I could turn my head upside down, and toss the hair around...didn't matter. I still came out with frizz free defined curls. However, at the time, my hair was very very long (I think the extra weight helped) and had little to no damage (i had regular trims, no chemical processing at all, well conditioned and cared for). I was also much more product happy then than now, and i believe i only used the blow dryer (my only vice at the time) two...occasionally three times a week.

Oh what i would give to be in that boat again.
