Don't use "permanent" dyes or blonding agents. When it starts to fade or grow out it looks ABSOLUTELY RETARDED, and if you constantly keep reapplying it every time it fades or grows out, you will seriously fuck up your hair.
If anything, use the kind of hair dyes that you have to reapply pretty much every day or so. Semi permanents at most, but honestly the kind that just washes out is best. You won't damage your hair, and you might look edgy rather than retarded. But honestly, don't do the whole thing, it won't look good if it's not a natural unless you have something like a professional clothing designer to give you a crazy outfit to go along with it.
