Medium hairstyles, like this super straight one are easy to do, and always impress. For a simple style such as this, a fresh hair color, or bold highlights can really amp up the look. Start by straightening your hair section by section with a brush and blow dryer. Go over each section with a flat iron to make the look extra sleek. Hair spray and shine spray can be used at the end to seal in the style. If you need extra volume, backcomb the base of each section of hair along the crown of your head, smooth it out and hair spray once more to hold.
