i've been thinking about shaving my head. my hair is kind of overworked and really nappy, and i've got terrible dandruff, so i was just thiking why don't i shave it all off. But, i would like to know how long it'll take to grow back to boy length.i have rabid,curly hair that is likely to take control of my head at any moment, so i'm fairly sure it'll grow back fast enough. i have a perfectly (seriously. it's like spherical) round head with no real surface abnormalitlies or features to make it interesting, and i only want to have short short hair for awhile. if anyone has any experience with shaved heads or any of that it'd be greatly appreciated.
