Every single toothbrush ever used is still somewhere on our planet. It’s gross and completely avoidable. Replacing your plastic toothbrush with a bamboo, compostable one is an easy step toward making your bathroom a single-use, plastic-free zone, as is replacing any single-use plastic razors with stainless steel alternatives.   Unfortunately, there isn’t much in terms of sustainable packaging for cosmetics, and what’s available is often expensive. That said, try to find out if any of your favorite brands offer a refill program (plenty do, and normally at a discount), or whether they have a recycling service. Garnier, for example, has partnered with TerraCycle and DoSomething.org on their Rinse, Recycle, Repeat program which aims to keep empty bottles out of landfills.
