Since I grew up watching it being done, I can offer a bit of info on the basics of the technique for an afro. First, thoroughly dry the hair as much as possible; water and fros do not mix. Second, do not braid the hair because this causes crimping and bending that cannot be removed. Third, add a light application of product, e.g., a creamy leave-in and a bit of oil/grease in order to keep the hair moisturized and avoid unnecessary breakage. Fourth, and most importantly, continually comb the hair as it fully dries, which will elongate it and remove the curls and kinks creating a nice, soft cloud of fluff. Fifth, once the hair is fully dried and elongated, it is the time to PickNPat - continually comb the hair with an afro pick before immediately patting and shaping it with your hands until it takes on a nice round shape. Keep doing the PickNPat until you reach the desired roundness. Also, do not try to cover, pineapple or otherwise alter the fro before going to bed, just lay down and catch some zzz's with the hair uncovered. In the morning, restyle with a few sprays of Afro Sheen before doing the PickNPat. If the Jermaine Jackson type of afro is desired, the hair must be curled (what is currently called a roller set) with tinier than usual rollers first.
