Another eco-friendly choice for your shower is to use shampoo that is packaged in recycled plastic bottles, like Love Beauty and Planet products.
Love Beauty and Planet bottles are made from 100% recycled materials and are again recyclable when empty. The company strives to not harm the environment and you with their products that are sulfate-, paraben-, silicone-, dye-, and cruelty-free!
This eco-conscious company makes shampoo and conditioners (among other hair products) for fine hair, greasy hair, color-treated hair, curly or frizzy hair, and much more. They also sell other eco-friendly bathroom products like hand wash and body wash.
I have used their shampoos from the Tea Tree + Vetiver and the Coconut Oil + Ylang Ylang collections. I love their fragrances, that they are naturally-derived, and that they are made from recycled materials!
