To begin, may I suggest that you only shampoo your hair 2-3 times a week? (And when you do so, please try to use an organic shampoo that is sulfate-free). Once out of the shower, gently pat hair dry with a towel. Run your fingers through it to detangle--no brushing!
Take a quarter size dollop of gel or hair cream (may I suggest Lush King of the Mods? It smells like a dream) and run through hair from roots to tips--just enough to lightly coat the hair. Too much gel will result in crunchy curls.
Feel free to let it air dry from here, helping to boost it at the roots. Or give them a head start by using a diffuser on the low setting to begin the drying process. Just keep in mind, too much time with the blow-dryer with dry your curls out.
Voila! All done--wear those curls wild like nature intended.
