Our model is wearing a prom look that could be worn up or down with the coiled cascades we see around her face. This could be a simple hairstyle for you to be able to do for yourself with practice. One example would be for you to divide your hair in the center after blown dry and section off the crown, sides, top and nape.
Use your curling or coiling iron in the lower back first, taking medium portions to curl. Allow them to lie in the curl when dropped. Do not comb out. Another way is to use medium sized hot rollers and wrap vertically.
When curled, simply take out the hair from the rollers and the best way, if you have the time; is to use conventional rollers and roll your hair while wet and allow to dry. When done right, your hairstyle should last all night.
