The 'Rachel' is named the most influential hair style of all time. 

I remember my friend in high school showing me a picture of Jennifer Anniston that she was taking to her hairstylist to have her hair cut that way.  I almost always try to take a picture with me to the hair dresser when I'm getting anything other than a trim. 

I took a picture of Tiffani Theisen (pictured at left) one time because she had that long hair for so long on Saved by the Bell (yes, I'm that old) and then one day she chopped it all off into a cute little bob.  Her face is very round, like mine, and I thought if she could do it, so could I.  I've also used pictures of Reese Witherspoon.
