Scrumptious-smelling Aussie Deep-Conditioning Treatment uses macadamia nut oil and mint balm (from Australia, naturally) to stop your precious locks from looking like you've spent too long in the sea. Available in travel sizes, the range, which includes a shampoo and conditioner, is teeny enough to chuck in your suitcase and as a bonus, the bottles are always funny to read if you're bored in the bath.
