Made from all-natural ingredients, byhumankind’s shampoo bar is vegan and ethically made. With base ingredients including anatto seed, hydrolyzed oat protein and rosemary extract, the bar comes in three fragrance options: lemongrass, thyme or lemon lavender. Our pick is the fresh, citrusy lemongrass scent—which boasts additional notes of lime and sage. Not only does the shampoo bar offer an alternative to chemical-filled options, it’s also minimally packaged, so it’s kinder to the environment. Additionally, it’s airplane-friendly.
