Style your hair as you normally would, whether you prefer it to be straight or curly. For a smooth look: Divide your hair into two sections. Keep the top layer of your hair separated with a hair clip. Gently, pull the flat iron through sections of your hair. Do this until your bottom layer is perfectly straight. Unclip the top portion of your hair and continue to straighten. For a wavy look: Place large, hot rollers throughout all of your hair. Leave the rollers in your hair for five minutes for wavy hair, 15 minutes for large curls. Take a rat tail comb and gently rat the hair at the top, back of your head. You can do this by lifting a small section of hair at the crown of the head. Start with the comb at the top of the section and comb through the section. Do this with a section of hair just below the section ratted. Comb the hair down, only slightly as to not flatten the hair. Use the end of the rat tail to divide your hair in half (just above the ears). Pull these two sections of hair to middle, back of your head. Use a small hair tie in the color of your hair to secure.
