You've gotten a lot of great responses, so I'll try not to repeat. Moisture is definitely the key with curls! I brush my hair before showering. After I shampoo, I squeeze all the water out of my hair using my hands, and THEN condition. (Your hair will soak up more conditioner if it's dry) I start at the ends of my hair, saturate them with conditioner, & work my way up. By the time I get to my scalp, I'm out of conditioner, which is good, since you don't want to condition your scalp anyway.
Don't leave the towel on your head a second longer than it needs to be. I usually put lotion on my body & then take the towel off. I run a wide-toothed brush through my hair, & then rub in a leave-in conditioning cream, again just to the ends. Then I make a messy part with my fingers, & run through a mousse for curly hair. I use a volumizing mousse to scrunch up the roots, & the curly hair mousse to saturate & form curls at the ends. I can let it air-dry at this point, & it looks great when it dries, about an hour & a half to 2 hours later.
Another way I sometimes style it--especially in the summer is to use spray gel. I like this a lot better than regular gel, because it distributes evenly, so you don't get that "wet" look, but your curls stay formed. I read that curly book that someone mentioned, & it's great. There's actually a recipe to make your own spray gel in there--you basically buy regular gel, & boil it with water. This will save you TONS of money on hair products.
You could also invest in a bunch of those tiny hair clips. You could put your hair up in a messy bun & then use 5 or 6 clips to hold it in place, & not only does it look MUCH better than a ponytail holder, but it's much nicer to your hair.
I can also blow-dry, but it takes ages, makes me sweat as I'm doing it, which only causes more curls/frizz at the scalp, & it's just not worth it to me. Plus, drying & then straightening gives you the worst split ends.
I don't have Felicity hair, but it's pretty curly & thick, & goes to the middle of my back. I have long layers put in when I cut it, & I always get comments about how soft & health it is. (I only blowdry 5 or 6 times a year). Hope some of this was helpful.
