I shaved my head Kojak style a few months ago. I liked the way it looked and it was much cooler, and I had planned on keeping it that way. Unfortunately I realized rather quickly that the time spent shaving on a daily or semi-daily basis far outweighed the time spent washing my hair, not to mention the increased expense of razors and shaving cream. I found it to be more of a nuisance than anything, which is a shame because overall I dug it. Now I just buzz it down to near nothing and let it grow for a week.
I think we should all shave our heads for C4.
