I shower every morning with the purpose of washing my hair, looks ridiculous and feels nasty if I don't. Perhaps it's conditioned to 'expect' it, but frankly I'd rather do it than stop for a period to find out.
I shower up to twice a day on the regular. I’d rather have dry skin than smell of BO. But even though I regularly shower twice a day, I only get dry skin in the dead of winter when ambient outdoor temps are sometimes as low as -25F.
