Plastic Shampoo Bottles Are Thrown Away Every Year.

That's the equivalent of lining them up across the entire coastline of California, twice over, every year. Our planet is burdened with an unimaginable amount of plastic.

Zero-waste shampoo bars are more than a haircare choice: they are a symbol of transformation. With each shampoo bar, you're taking a firm stand against the plastic tide. Imagine the difference we can make.

Too soon to tell if it’s darkening my hair, but it does leave it feeling soft and clean.
