Part the top third of hair from temple to temple and clip it out of the way. Use a mixed bristle brush, like a Denman Grooming Brush, to smooth bottom portion of your hair into a low, side ponytail.
Next, you want to dry both sections of the hair separately with a blow dryer with diffuser attachment on medium to low heat settings. For voluminous curl, try the Bed Head Curly Pop Diffuser Dryer.
Take the top third of hair and place it into a very loose side ponytail (opposite of the bottom ponytail). Using the side of your brush to gently smooth any fly aways, place the ponytail holder an inch or two away from scalp. Then push the pony toward your head until your roots pouf to the desired height. Pin the ponytail holder in place to keep the bouffant.
