Woohoo dude - welcome to the club. No soap. No shampoo. No deodorant. No toothpaste. Exfoliating shower gloves. Citrus, vinegar and olive oil, for soap and shampoo. A muslin bag filled with rosemary, thyme and/or citrus peel, jasmine. Just jam them under my armpits. Baking soda and water into a paste for teeth. OK it doesn't improve my looks and there is a lot of prep work involved - but it does wonders for my body or my mind. Not sure which.
