I put a ton of product in my hair. After I diffuse part way it takes 3-4 hours to dry. I rarely just air dry, but I'd guess 5-6 hours?? with product in it.
If my damp hair is allowed associate too closely with other hairs (in rollers, in damp pineapple, pin curls, etc.), it will form a union and refuse to dry. It must take a little while to organize the union, because it will be a tad dryer, but not much. Good thing I'm not living before the 1960's because my hair sets would never dry.
