Our shampoo bars are made with plant-derived ingredients and botanicals. Some of them are extracts, so different parts of the plants (flowers, leaves or resins) are subjected to an extraction process. This involves isolating certain components present in plants - which means there is a much higher concentration of those components in the solvent used. In addition, there is a common misunderstanding that as long as a product is made with natural ingredients, they are safe and non-irritating. This is not true. There are plant materials that can cause issues if we don’t use them carefully, eg. Shikakai or essential oils. Shikakai in high concentration can cause eye irritation. In case you have very sensitive eyes, we ask that when you are using our Herbal Therapy bar or the Finer Things bar, try not to have your eyes wide open during the wash.
