  A layered hairstyle is created by snipping random pieces of hair in varying lengths, with sections kept long. Adding layers generally does not remove any length from the hair; it simply eliminates some of the bulkiness of hair that is all one length. Layers add flexibility, volume, and definition to hair. Three popular layered hairstyles are long layers, the shag, and the graduated bob. Stylists can tailor any of these hairstyles to flatter face shape and suit individual preferences.
  
  

Long Layers

• One of the easiest ways to wear layers is to keep them long. In this style, layers are typically cut no more than a maximum of three inches from the ends. Keeping layers long adds movement and body to hair, and gives you freedom to experiment with styles, such as flipping the ends up or adding a little wax for a piecey effect. This cut is versatile, easy to maintain, and doesn't look like a drastic change, since the overall length isn't shortened.
  
  

The Shag

• Modern shaggy haircuts became popular in the '90s when Jennifer Aniston's character, Rachel Green on the television show "Friends," debuted "The Rachel" cut. Shag cuts use layers of different length to add volume and movement to hair. Although it can be tailored to your face shape and personal preference, layers are usually cut relatively short with this style to create its signature look. This cut is usually kept at medium-length, and falls no longer than the shoulders. With this cut, trips to the salon should be made every six to eight weeks to freshen up and define layers.
  
  

Graduated Bob

• The shortest of all hairstyles listed, the graduated bob is angled to be longer in the front and shorter in the back. The overall effect is sleek and smooth. This hairstyle was once considered edgy, but as more celebrities adopt it, it is becoming a staple style.
