Shampoo bars are not soaps and are similar in composition and care to a liquid shampoo. For our shampoo bars, we use a gentle, vegan surfactant made from the fatty acid of coconut oil, which is approved for natural cosmetics. The shampoo bars are very economical, foam very well and are easily biodegradable. Rub shampoo bar over wet hair, massage in, rinse, done! For faster oily hair with nettle, lava clay and a lavender herbal scent.
