About Hair Care

Sustainable hair care, starting with zero waste shampoo and conditioner bars. Each 3 oz shampoo bar lathers like liquid shampoo and lasts 75+ washes, replacing 2 to 3 plastic bottles, and the conditioner bar glides on without lather. Both come in 12 scents, with picks for curly, color-treated, gray and sensitive scalps, packed in a compostable cardboard box. They are vegan and cruelty free, with no SLS, parabens or silicones. Zero waste hair care goes beyond the bars: save with the shampoo and conditioner bar duo, keep bars dry on a bamboo soap dish, and finish your eco friendly hair care routine with a bamboo hair brush, a sandalwood comb, plastic-free hair ties and dry shampoo.
