Swanson Icelandic Secret Volumizing Shampoo is the smart choice for clean, healthy, voluptuous hair that exudes radiant beauty. The “secret” ingredient that makes it so remarkably effective is ChitoClear® Chitosan, a polysaccharide that interacts with hair's keratin to enhance moisture retention, making hair softer and more manageable while protecting against heat and sun damage. Combined with aloe vera gel, vitamins A, D and E and a synergistic blend of botanical extracts, it makes one beautifying secret that we’re delighted to share.
