Haven't been using toothpaste, deodorant, and shampoo for years
It has been years since I last used toothpaste from a tube. Instead, I use my own concoction of baking soda, peppermint essential oil, and water to brush my teeth. Completely edible (though I don't swallow it).
I use wet baking soda in place of deodorant, too. Rub a bit in my armpits, and they smell even less than when I did use deodorant. I also don't get rashes like I did with the gel kind of deodorant.
I quit using shampoo, too. I used Head & Shoulders, because I had issues with dandruff. I tried baking soda and apple cider vinegar, but I found that was not good for my hair. Prolonged use made the dandruff worse. I found a natural, no-poo alternative that took care of the dandruff, but it was expensive. Then after reading this article by Nat Eliason, I stopped altogether. Just wash with water, and occasionally with diluted Dr. Bronner's soap, and the dandruff went away! (Could also be diet change as well...)
I Stopped Using Shampoo, and No One Can Tell the Difference - Nat Eliason
6 months ago, I completely stopped using shampoo and conditioner. I'd arrived in Argentina, and when I unpacked my bag, I realized I'd forgotten to pack either shampoo or conditioner. Normally, an Airbnb would provide these, but for some reason, they hadn't.
I also stopped regular use of soap in the shower, and mostly clean with water instead. I get a nice neutral, natural clean smell, instead of some inorganic perfumic scent.
Artificial chemicals disrupts the microbiome balance on the skin, and strips away the natural oil from the skin and hair. From my research and then experience, I've discovered it's healthier (and cheaper) to go these more natural routes.
