In 1970, Dr. Dennis Sepp, an organic chemist, began exploring natural, ayurvedic ingredients for hair and skin care. As a scientist, Dr.Sepp knew that the natural world offered functional ingredients that were better and safer than conventional chemical ingredients. His first study was with shikakai (Acacia Concinna), a traditional Indian herbal used for cleansing the hair. He created a water soluble extract from shikakai powder that maintains the effectiveness of the ancient remedies. The result was ShiKai shampoo, and the beginning of our natural products company. ShiKai now manufactures more than 50 products, sold in premium markets all over the world. At Shikai, we are proud of our products and our loyal customers. We offer a 100% money back guarantee if you're not completely satisfied. Manufacturer Warranty Included.
