I don't know about most naturals but for me, when my hair is wet, it doesn't get straight but the curls are looser and more defined, I have more ringlets, and it hangs down. At this point, the only time I can put my hair in a ponytail is when it is wet. When it is dry, I can no longer put it in a ponytail nor does it hang down as much because of the shrinkage.
