A shampoo bar is a solid, concentrated version of liquid shampoo. It cleanses your hair just like a regular shampoo but without the plastic bottle. Our bars are packed with natural ingredients, essential oils, and nutrients for healthy, beautiful hair.

Wet your hair and the shampoo bar. Rub the bar directly onto your scalp in gentle, circular motions, or lather it in your hands and apply the foam to your hair. Massage thoroughly, then rinse well.

Our packaging is completely plastic-free. We use post-consumer recycled fiber, meaning it’s made from paper materials that have already been used, then collected, cleaned, and transformed into durable, eco-friendly packaging.

This helps reduce waste and gives new life to existing materials instead of creating more plastic. ♻️

Thanks to this approach, together with our customers, we’ve already helped keep over 200,000 plastic bottles out of landfills in 2025.
