I might as well put my input in again.
Well, if you want my sort of hairstyle (Just search through pictures of yourself thread) all you have to do is the following:
Apply gel to hair (mainly around the roots)
Tease hair into general spikes, however you wish them to go (I just do mine to the right)
Use straightener to define the spikes, and apply a bit more of gel to the tips.
I like to curl the ends of my spikes/mullet, but it's up to you.
Just adjust this to taste, really.
There's not much else to it, unless your hair is short, which makes it even easier.
Just apply gel throughout, starting at the base, spike to your tastes, then just hairspray to keep it in place.
