I decided to switch from a regular liquid shampoo bottle to a shampoo bar that I bought at a local fair from a lady that makes them.
Shampoo bars are more sustainable than recycling because they are zero waste. In an ideal world, most items should be zero waste or reusable and recyclable as a last resort. Most shampoo bars have no packaging or at the very least come in FSC certified paper boxes. They're also completely biodegradable.
