Shampoo and conditioner powders are the latest innovation in the world of eco-friendly hair care. I thought I had tried every green, plastic-free, refillable, compostable, all-natural hair-washing method until I received two emails in the same week from companies now selling these washing powders. “Powders?” I thought in confusion, and promptly accepted the samples they were offering. One came from a brand new startup called Cocofomm, the other from established eco-beauty brand Meow Meow Tweet. Both arrived in paper envelopes and consisted of a light-colored granular powder. Cocofomm’s delivery came with a small shaker bottle, but as founder Liz Qiao-Westhoff explains, any leftover spice shaker will do. That piqued my interest because it’s a zero-waste product that makes use of packaging most people already have at home, and the envelope in which the powder comes is plastic-free and compostable.
