with a round brush. Start with damp, freshly-washed hair. Blow dry your hair straight by running your hair between a hairdryer and a round barrel brush. Keep the round brush under your hair, and the hair dryer over your hair. Use a flat iron to smooth out flyaways.  If you don't have an excessive amount of flyaways, rub a pea sized amount of serum in the palm of your hands and apply it to your hair to tame the flyaways. Work in sections from 1 side of your head to the other. You can use this technique on bangs as well. Make sure that your hair is dry first. Apply a heat protection spray, then let it dry as well. Use a flat iron to straighten your hair like you normally would. As you reach the ends, twist your wrist to rotate the iron upwards. Let your hair cool before setting the style with hairspray. If you have curly hair, blow dry it straight with a round brush first. Keep the brush on top of your hair rather than under it so that the ends curl outward. Touch things up with a flat iron, if needed. Apply a good heat protectant, then blow dry your hair as straight using a round brush. You can also use either a paddle brush or a blow dryer with a comb/pik attachment. Gather the upper three-quarters of your hair into a bun, then straighten the bottom layer with a flat iron and a low-heat setting. Let down another layer of your hair, and repeat the process. Keep going until you reach the top of your head.  To get your hair straighter, place a fine toothed comb below the flat iron as you run the flat iron through the length of your hair. You may have to work in smaller sections if your hair is very thick. Apply a hair oil or serum to smooth any stray strands and add shine. Apply a high-shine gel to your hair, from roots to ends. Comb your hair back with a fine-toothed comb, so that it flows away from your front hairline and the part disappears. Apply more gel to the top of your head as needed to finish the wet look. Leave the ends alone. Straighten your hair first, if it is curly or wavy. A thick, fabric headband will look trendy, but if you want something fancier, try a decorative metal one instead. Experiment with brushing your hair straight back, away from your hairline, or parting it down the center or off to the side. Make sure that the headband that you are using goes with the rest of your outfit. For example:  A thick, fabric headband will look better with a casual outfit than a fancy outfit. If you are wearing jewelry, match the metal headband to whatever you are wearing. Pair gold jewelry with gold headbands, and silver jewelry with silver headbands.
