Being biracial isn't always reliable in predicting curl outcome. My sibs and I have different hair types. My bro's is almost straight. One of my sis's is close to afro textured. And for all I know the OP is biracial (though it really doesn't matter either way). Both men look very mixed to me (and both happen to be good looking)
