CosmeticsAlong with the kitchen, one of the biggest culprits of plastic is the bathroom. Between lotion, shampoo bottles, and toothpaste tubes, you may not even realize how much of your plastic use comes from the bathroom. Consider making your own toothpaste, buying lotion in glass jars that can be reused, and using shampoo bars instead of liquids. This change has the added benefit of helping improve your health and limits your exposure to toxic chemicals.
