why do you think that almost every guy in a Metal band has long hair?

To Headbang ... \m/
and its Hot lol

to headbang!!!!!!!! balls to the walls

imo i think its madami of a stereo-type.

It could be a stereotypse i'm not denying that but it could also be for headbanging, although people with short hair seem to be able to headbang perfectly fine :) I think it's madami a metal/rock thing. If you don't have long shaggy hair you're not the part kinda thing LOL. But in my personal opinion i think it's because the ear plugs they use to protect their ears are crap, so they wear their hair long to have added protection :P LOL

To "headbang".But this is a style now.If you like Metal music so much you can have long hair.
It's cool.

because they are just lazy to get it cut

Because it looks cool, and it sets them apart from others.

most do but its the metal signature but bruce dickinson the singer 4 iron maiden doesnt

They have no time nor money to cut it.

I would say it makes headbangin' alot madami fun...too lazy to cut it Perhaps. Money? No, guitars, drums, and other equipment is expensive so of course they can afford a haircut! Its the look, its fun, and its what makes heavy metal so unique and special!

It's a way to give off a heavy metal look. It was popular in the 80s, and it just kind of carried on to metal bands today or metal bands in genral, it's the style. Long hair just kind of resembles metal, like how cowboy boots resemble country music and how glitter and saggy pants resemble pop/rap. >_<
