Many celebrities are having their hair left long and many layers being cut. Most flattering is the layer cut that highlights the face with whispy bangs.
Some of the best cuts are not cuts at all, but styles, utilizing accessories. You can go up, waved, permed. Use braids, buns etc, search online for easy How-To's.
If you don't want to let your long hair hang you can try chaging the texture for a new style- if it's wavy, straighten it or if it's straight, give it some curl or wave.
