We couldn’t help but put Emera on this list one more time. While this isn’t technically a shampoo, it can be used as a leave-in shampoo for curly hair, thanks to the antioxidants centered in the avocado and hemp seed oils. Antioxidants help to break up bacteria from forming, which is generally what causes scalp infections, and can be one of several factors in itchy, dry scalps that produce dandruff. After your curly hair has had time to dry, you have a short while until it gets frizzy again. It’s a harsh truth we all live with.
