Is It Ok To Shower Twice And Week?
Depends on how much moving around you do and how sweaty you get. also whether your meeting others often.
washing hair only on Wednesday and Saturday?
Twice a week is more than enough for most.... some people like Gary Barlow never wash theres- its self cleaning apparantly
Unless you have a particularly sweaty job or pastime body odour is not a problem for most people. Others can shower daily & still stink to high heaven. (I've worked next to some of them!)
i shower once a day, and feel that is enough to be clean. I have also worked with people who's hygiene left a lot to be desired, though i wouldn't have asked them if they showered once a day.........
