Guys do not like when girls put gel or moose or whatever the hell else is popular these days into your hair. We like silky smooth shiny nice touchable hair. Hair is the number one must underrated feature that you girls think we do not pay attention to, but we see it. Bad hair is like bad teeth, gross and disguising, not going anywhere near you. So take a few extra minutes in the morning, blow dry, flatten, do whatever the hell you have to, buy some herbal essence, He doesn't know, but for He-sake and your sake, make your hair look good.
