If I really pick at it, I start losing curl but what I can do is (and i do it often during the day) shake out with my hands. I very carefully slip my hand underneath and shake. Any areas that have gone a bit flat usually curl back up and fluff up (no frizz). But, I don't like clumpy curls on me. My hair is too fine and thin for clumped curls. I get bouncy ringlets that are more fluffy.

Fine, thinish hair/3a, 3b
