Man, all this sounds so familiar.
I'm half Indian. My mother (Indian) has some kind of wavy hair, which is easier to wear straight without poofiness. Although, looking at older pictures it does look kind of poofy.
Anyway. After washing my hair and towel drying it furiously, she would blow dry it (without a diffuser), comb it, oil it with coconut oil or amla oil and braid it. I always showered at night, and this way, the next day I'd end up with more "managable" hair. Which she would brush more and then either braid, put in a ponytail or something like that. It was never straight this way, but for some reason I always considered it straight. I just thought it was "frizz". I'm actually 3a though.
