I had really long hair too! Everybody at my dance studio would always play with my hair and say it was very long and pretty.  I loved being told that! The hairstylist that I go to told me we needed to cut off all my dead ends and it will grow faster and much healthier.... ya bad mistake! never cut your hair if its long! its in style now, so if you have long hair keep it long! i didnt cut it too long atleast so its not short but i still want it at my original lenght.
