For me, it's hair.. Every single lyric is applicable to my life in some way or another.. This song has probably been my favorite out of her entire discography. I remember the day it came out, I thought it was the best thing I have ever heard! Lol. I just realized the other day that the message of this song is talking about the exact same thing I have been going through lately.. which is accepting myself yadayada... not feeling like I can be myself.. I just really love this song.
