Responsibly sourced palm oil

Responsibly sourced palm oil

Our shampoo bars are palm free. Our decision to use minimal palm oil based ingredients instead of alternatives such as coconut oil based ingredients for a few of our actives in our conditioner bars stems from our understanding that palm oil uses less space, produces less greenhouse gasses, and requires less energy. In the few instances where we use palm based ingredients, they are always RSPO certified.
