haha..
okay-- so i used to do this too-- i'd spend time using gel making my hair 'look' messy...... when in reality it usually took less time to actually make it look good.. and even less time to leave it naturally messy.. and just not touch it after i got out of the shower..
reminds me of people who rice up there car just for the looks-- trying to fit a certain image-
anyways-- back to your question-- i guess it depends, but if your weraing a business suit, for business reasons- its probably not a good idea becuase you want to look as professional as possible.
