What You Should Be Doing

Part hair and section off the top: Depending on what kind of hairstyle youre trying to achieve, decide where youll want to part your hair. If youll be styling it straight back, you wont need a part. Next, section off your hair by creating a toplayer and an underneathlayer. The idea is to tease the underneath layer and lay the top layer over it, leaving hair looking finished and polished instead of messy.
Take the underneath layer and begin teasing with comb: Clip the top layer away from the underneath layer. Taking your long tail comb, gently tease the underneath layer by backcombing towards the root. Begin by combing about two inches away from the root, then move to three inches away, and so on. The bigger the tease, the bigger the hair, so its up to you how much to comb.
Smooth back the front section over the teased section: Once youre finished teasing, unclip the top layer and comb it smooth, laying it over the top of that bottom layer to cover the teased hair. This way, your hair looks like its got a ton of volume, but theres no evidence of teasing.
Spray with hairspray: Once you style your hair, spray the flexible hold hairspray to get the look to stay in place. Voil?!
