Aussie Miracle Moist Shampoo For Dry, Really Thirsty Hair, quench your hair’s thirst with this moisture infusing shampoo, with Australian Macadamia nut oil. Native to the land down under, the Macadamia nut has been used in Australia for centuries for its moisturising properties. But thanks to an intrepid 19th century explorer (who luckily for us didn’t get lost in The Outback), the rest of the world was let in on the secret. Cheers dude!
