This solid shampoo bar is lightly scented with lemongrass and tea tree essential oils and was designed with bonus oils to promote scalp health. Never used a solid shampoo? Simply brush the bar 4-5 times across wet hair, then easily build up a luxurious lather with fingers. When not in use, keep shampoo bar out of the line of water, and allow it to dry. A single puck of shampoo can outlast 3 bottles of traditional shampoo, and no plastic packaging! Made from all naturally derived ingredients.
