Use either a comb or a pair of children’s scissors (be safe!) to part a clean circle in the center of the back of the head and pin back remaining hair and put the hair in the circle into a ponytail.
Divide the ponytail into multiple smaller ponytails.
CUT! (we used fabric shears but an exacto knife could work just as well).
Remove ponytails and trim the hair as short as possible in preparation for shaving.
Use an eclectic razor to remove the bulk of the fuzz.
Touch up the edges of the circle using a small eyebrow razor and your roommate’s shaving cream. Be careful as a dutiful and courteous tonsurer to not cause bodily harm to the tonsee.
Depending on artistic choices, you can give the remaining hair a trim as well. We decided to go with the classic roman-monk style bowl cut, but other interpretations are encouraged. Tonsure diversity!
Enjoy and, if desired, lather on some lotion for extra shine!
