If you want to add more volume or more 'personality' as a stylist one said to moi a few years back, then adding layers as in cutting the hair in different lengths like layers on a dress helps to add volume, soften the face, and so many more positive things. I have gotten my hair cut into layers for the last six years and it is cute when you put it back into a ponytail and I get what my mother likes to call the rooster's tail.<br/><br/>Layered Hair (http://en.wikipedia.org/wiki/Layered_hair)<br/><br/>It seems there is even science and math to where you exactly cut the hair into layers.
