how often am I supposed to shave my head?

As others have said already, it's a personal choice, and also depends on how well your scalp adapts to being shaved. I tend toward the lazy side when shaving, so I may only shave twice a week sometimes. My job doesn't demand that I be clean shaven, or that my facial hair be trimmed within an inch of its life, so I save lots of money on shaving stuff.

thank you all
I've decided to shave it every day.
I so hate the feeling of non-shaved, I feel...dirty ...
I just LOVE the smooth feeling, though it's not 100% pro, I'm a beginner and I'm doing my best:D
I'll get the hang of it within a few days

Welcome to the club of daily shavers. I also feel much better after shaving

i have a tough scalp so i can do it twice a day and even some touch-ups during the day when need be

Every day, in the shower.  Twice a day when you want it to be really smooth and shiny.  Especially twice a day, when going to the beach.   Just My Opinion.

I work rotating shifts so sometimes it's hard to do the every day thing. I like to have at least three days growth before I shave but if I wait longer than ten days, I end up going to my childhood barber who charges $10 to shave head and face. More often than not I shave Monday morning after working weekends, Wednesday morning after working Mon/Tues and on Friday after working Wed/Thurs though I don't follow this rule all the time if something comes up. I still tend to break out on occasion so down the road I might go to every other day (One day I will post a picture of my weird balding pattern)
