I drive around the city with windows down top down mostly, and I don't find the wind too much to handle with the deflector on. I lift the windows up for highway travel but most of the draft only hit top of my head, didn't bother my hair too much at all.
I think you must have silky smooth hair for the draft to bug you that much, I think you should take it as a complement and enjoy the open wind a bit more. especially in this nice weather right now.
the alternative is to wear a nice helmet and drive as fast as you can.
