The next evolution in hair care has arrived with our Swanson Ultra Tea Tree Oil Shampoo and Conditioner. We took the old formulas, removed all the parabens, took out the sodium lauryl sulfate (SLS) and added in a special herbal complex for beautiful, healthy hair (and scalp). This Australian wonder contributes to the health and appearance of your hair and scalp unlike any other oil, at once defending and nourishing without drying or leaving behind an oily film. Because we use no SLS—a common foaming agent found in cleansing aids—these products may not produce the lather you're accustomed to. But don't be fooled! Swanson Ultra Tea Tree Oil Shampoo and Conditioner produce remarkably beautiful results without potentially harmful or unnecessary ingredients.
