JASON Normalizing Tea Tree Treatment Shampoo gently cleanses and nourishes to minimise dry, flakey skin build-up on the scalp. Australian Tea Tree Oil, known for its antibacterial and anti-fungicidal properties, is combined with Grapefruit Extract and protein to purify and fortify hair follicles while soothing Calendula, Hops, Sage Extracts and Wheat Germ Oil, helps relieve discomfort of itchiness. Gentle enough to use everyday, hair is soft with added volume, luster and manageability.
