Our Considerations For Choosing These Zero Waste Shampoo And Conditioner Brands

So, how did we choose these sustainable shampoo brands

Here are the criteria we used. 


B Corporation (B Corp), Carbon Neutral, Ecocert COSMOS Approved, Fair Trade Certified, Orangutan Alliance, People for the Ethical Treatment of Animals (PETA), Cruelty Free International (Leaping Bunny or Choose Cruelty Free), USDA Organic, Vegan Society, rePurpose Global, Fair Tax, Living Wage Foundation.


What’s inside the plastic-free packaging is just as important as the packaging itself. We looked for natural, non-toxic, plant-based ingredients that have been responsibly sourced. 


We looked for purpose-driven brands that put people and the environment first. Cruelty-free is non-negotiable and many of the brands, while not always fully vegan, offer vegan-friendly options. 


How can we reduce plastic waste in shampoo? 

Bar none (pun intended), the best sustainable packaging for shampoo is none at all! Naked bars are the perfect zero-waste packaging solution. If they come in boxes, these should be recycled and recyclable and printed with sustainable ink. 

For dry shampoo or powdered concentrates, recycled cardboard or recyclable metal containers fit the zero waste bill. 

Ethical Sourcing: 

Being able to fully trace ingredients is crucial. Fair Trade certification, where possible, is ideal, especially for ingredients like cocoa butter and coconut oil. 


Many brands on this list hand-make their products in small batches, minimizing waste and carbon footprints. 

Other ways to reduce carbon include using renewable energy and practicing carbon offsetting. 

Paying It Forward:

Healthy hair feels great, and so does knowing that a brand gives back to worthy causes.
