A lot of waste generates from the soaps we use in the shower. Take advantage of bulk soaps, shampoos, and conditioners that are either sold package free or in paper.
I typically buy shampoo and conditioner bars but recently have found a company called Plaine Products that have a circular business model with their products. You should check them out!
I keep my shampoo bars, conditioner bars, and body soaps in metal containers to keep them from getting wet when not in use. These bars last forever! I can probably get 3-4 months out of one bar and that’s if I wash my hair every day. Money saved. I’ve also been able to find package free soaps at farmer’s markets and health food stores.
You could also ditch the shampoo altogether by doing the “no poo” method which means using baking soda, apple cider vinegar, or just water in replace of shampoo. It works for some people.
And of course, making your own soaps is also an option.
For hand soap, look for loose bars that most grocery and health food stores sell.
