Natural Instinct is one of Australia's original natural skin and hair care pioneers, with more than a decade behind them and their own natural ingredients standard. I stock the anti-dandruff shampoo and conditioner because it's one of the best natural anti-dandruff haircare ranges I have found, made with tea tree and thyme oil alongside aloe vera and vitamin E. I don't stock the full Natural Instinct range, as not everything meets my ingredients policy, but these do.
