Body-building shampoo for BIG hair and loads of shine Over half the base of Big shampoo is made with sea salt, giving massive volume to hair in need of a boost. Sea salt is also full of minerals and de-greases hair, removing dead skin cells and dirt without stripping natural oils for a fresh, squeaky clean feeling. We balance the sea salt with seaweed infusion, extra virgin coconut oil and avocado butter for soft, nourished locks. Finally, fresh citrus juices are squeezed in for incredible shine. It's no wonder this one is a best-seller!
