Hey guys. I dyed my hair today for the first time (from natural darkish brown which looks FUGLY as hell in the sun, to jet black). Seeming it was my first time I found it reasonably easy and thats kind of the reason I opted for a black semipermanent dye because if I messed up somehow I could wash it out reasonably quick and it wouldnt look to strange.

Anyways, I'm looking for a permanent / semipermanent dye thats a non-natural colour (Perhaps blue). Seeing my hair is darkish, I've read online that I'd need to bleach it first. There is no way I'm gonna mess around with the bleach so the dye would need to have bleach or something pre-mixed into it. 

So do any of you know where I can get something that meets these needs in Auckland? I don't really want to order it online just incase something happens. How much does it usually cost to get this done in a hair salon or something?
