Leave your bottle behind! New 2-in-1 Shampoo & Conditioner Bar is a super concentrated, all natural and eco friendly alternative to traditional liquid hair washes. While most commercial shampoos and conditioners are 90% water and come packaged in a plastic bottle, the crafters came up with an ultra concentrated, color safe formula that supports both hair and scalp health. Long lasting and great for Mama Earth, one 4 oz bar is equivalent to a 20 oz bottle of liquid. They're also great for travel and camping!
