Was chatting at work, and apparently some shower once every two days, some every day, some twice a day. One young bloke longest streak was 6 days he said, he realised it was too long when he got pimples on his back.
I'm interested in your longest streak, but more interested in ozbargainers habit.
Edit:
Perhaps interesting to note that Steve Jobs used to shower only once a day. He was so stinky that nobody wants to work with him, so he works at night.
The amount of crud I put in my hair as a girl to keep it in place and healthy entirely warrants shampoo tbh. I don’t know many guys who use product as regularly as the women in my life.
