If your kids have left your shower overrun with their old products, there’s an eco-friendly solution that will make you both happy: recycling them. After you’ve finished up the products, companies like Terracycle will take the packaging and recycle it for you, creating new product packaging out of the recycled material. And even if their particular personal care products aren’t your cup of tea, you can always use extra shampoo to clean your makeup brushes or use leftover conditioner as shaving cream.
