Soapnuts are a dried shell which can be used an alternative to chemical cleaners. They are totally hypoallergenic, very sustainable and can be used for many things - as a multi-purpose cleaner, clothes detergent - and now, shampoo. This vegan society approved rosemary and marshmallow shampoo smells delicious. It is so gentle it can be used as a body, or even face wash too. But that doesn't mean it doesn't do the job. After lathering up, my hair felt clean, and was deliciously, but not overpoweringly, scented. It left my locks with a definite sheen and softness that lasted for a couple of days. This shampoo combines a good, natural product with an ethically-sourced ingredient.
