I was surprised to read on one of the other forums that a lady showered twice a day.
My husband before he retired showed at work before coming home. He did work that required this.
Into retirement I shower two to three times a week and wash my hair once a week. A strip wash daily for me is fine unless I am doing heavy gardening work.
My understanding was that showering too much is not good for us.
