Why We Love It: This pure essential oil is an antiseptic and strong fighter of bacteria on the scalp, so it only makes sense that we use it in our Tingling Clarifying Shampoo.  Tea tree oil helps control buildup, reduce inflammation and supports a healthy happy scalp. Rich in antioxidants and vitamin E, this ingredient will keep your scalp fresh and clear by balancing its ph. Tea tree oil has been known for thousands of years for its benefits of being able to cleanse without causing dryness. This potent oil always needs a carrier, which makes it marry well with the rest of ingredients in our shampoo bar that are designed to clarify and detoxify your scalp.
