I like the feathered kinda look from the 80's personally, which goes with my somewhat wavey hair (at least when it's long; short it's actually kinda curly) since it naturally feathers out without much effort.
Really don't do much. I just don't cut it (it's been over a decade since I even went to a barber). Keep it clean, conditioned and I can just brush and comb out any tangles and help the feathering out and look like I belong in A Flock of Seagulls.
