Depends. If I want it to stay bright, I dye it about every two weeks (same as when I shave the hair down). If I can't find/afford/be arsed to go buy dye and I run out, I let it fade away almost gone (as seen in this picture from a day or two before I dyed it blue).
Old men, fear me! You will shatter under my ruthless apathetic assault!
