Hope.. I can comment and is ok... I am not bipolar,,, but DID... and well.. thru the years my hairstyle changed dramatically... at times as different alters had stronger control... one time.. I had waist length hair.. and well out of the blue my mood changed.. next day it was about an inch long...

grew it back out waist lenght again.. but.. yes.. as my "moods" change so does my hair.
