Don't have much hair, buzzcut through choice, so it gets washed at least once a day, normally twice as I shower after getting home from work.
I can't believe that I am bothering to post on a thread like this, next we will have questions like how often do you cut your nails, do you keep your earwax and nasal hair.....
Haven't got any hair left so doesn't really apply but I tweezer my nazal and ear hair once a week on average if that helps and I shaved my partner's pussy the other day which was kinda fun
