Promising review: "I have super oily roots with dry ends, and itchy scalp. Before I tried this product, I had to shampoo my hair daily. Where as now, I can shampoo every four days, and in between, I just use this hair rinse. It's a lifesaver for me with my oily roots as well as itchy scalp!" —nnv20
