For a relaxed style that conveys sophistication, a textured medium style should suit you. The key to this style is to ensure the added length looks intentional and not like an overgrown short style that missed its appointment with shears. Go for a longer bang and sideburns, ensuring thickness and bulk is taken out by having your stylist use texturizing shears. To keep the look modern, avoid sporting a harsh part in the hair. An example of this look can be found on actor and musician Jay Chou.
Products to help achieve this look are: American Crew’s Defining Paste, Bed Head’s Mastermind Cream, or Bumble and Bumble’s Sumowax.
