Look up pixiecurl diffusing. It really works. My hair takes forever to air dry, and because it's windy here I really can't go outside with it wet (or at least not until the gel cast starts to set), so I have to diffuse. I can pixiecurl enough in about 15-20 minutes that it only takes another hour to finish air drying, at least in summer. In winter, I'll probably have to diffuse a little longer. I get no frizz with this method.
