It's so hard to pick!! I love so much his long and curly or straight hair!!! so hot, so perfect!! he's so beautiful with long hair and short hair too.. I mean.. look at him in Thriller era or in TDCAU, YANA.. he's just awesome!!!!
long or short doesn't matter makes him look hot XD.
I love long the most it suited Michael XD back in the 80's, 90's and 00's.
in the 80's other artists look like hippys with long hair -_- but Michael didn't XD.
