Hi Lea...I'm an ex-hairdresser...I'd go with what Chon has suggested. Also, shampoo, condition and use a leave in moisturiser, but perhaps use your fingers for styling when wet. The more you attack it when it's dry, the more it'll have that frizzy, fuzzy look.

The curls look pretty well defined in the first photo...and your hair looks healthy and shiny. Definitely try some of the curl defining products as a start and perhaps use a moisturising treatment once every couple of weeks if you feel the ends feeling a little "crunchy". Regular trims will help keep the curl in check too.
