Razored Bob

  She may like the edgy, youthful take on the classic shoulder length bob. This haircut is done with a razor and includes layering to frame the face. Far from the conservative bob that turns under at the ends, this style was popularized by actresses such as Jennifer Aniston, and boasts plenty of texture and body. Ask the stylist to angle the length forward toward the jaw for swingy movement in the cut unless your teen wants to wear a ponytail.
  
  

Shag

• She'll find this low-maintenance layered look versatile for styling. Characterized by fuller layers on top, the modern shag is a tousled style that frees curls and waves from being weighed down. Your teen will be happy that she can still clip her hair up off her neck thanks to the length or even pull it up into a roughed-up french twist. With plenty of layers to play with, she'll enjoy using jeweled hairpins or clips to change up her style. To maintain the tousled look, she'll need mousse for volume and light control instead of hairspray.
  
  

Undercut

  If your teen's hair is straight, she may like an undercut. Your stylist will slice in shorter layers underneath in the back to add swing and movement to a sleek, smooth haircut. She'll love the playful flair the undercut adds to an otherwise simple, shiny blunt cut. This strategic layering also increases the body and volume, making hair appear thicker. Use mousse or styling cream to keep this sleek, modern style at its best.

  Refine her blunt cut style with some layered sideswept bangs to flatter any face shape. Sideswept bangs add interest and volume to the haircut and draw attention to your teen's beautiful eyes. If she's anxious about going layered all over, start with the sideswept bang to see how she likes it; the addition of those face framing layers make her hairstyle more elegant and eye-catching.
