Facial oils, product and bacteria can accumulate in your makeup brushes. This can negatively affect the health of your skin and eyes. Regularly shampooing will prolong the life of your brush and improve your complexion.

Run warm water over the product to moisten. Wet, swirl and lather brushes on the surface of the solid shampoo. Rinse brushes and repeat until water runs clear. Lay brushes flat to dry. Prior to closing the jar, let the solid shampoo dry to the touch. If using the unpackaged (bar version), place it on a slotted soap dish to dry between uses.
