How to Use and Store Them

Application: Wet your hair completely, then either rub the bar directly onto your scalp or lather it between your hands first. Massage the roots and rinse thoroughly. Storage: Most users on Reddit's ZeroWaste forum agree that keeping bars on a slatted or draining dish away from sitting water is essential to prevent them from melting or dissolving too quickly. Transition Phase: Expect a brief 2-to-4 wash adjustment period as your hair clears out old silicone and sulfate buildup from liquid shampoos.
