Spa star treatment of the month: Avocado Hair Masque, Alila Villas Soori, Bali

Remember when you bleached your hair, then went on holiday and jumped in the pool? Green locks probably weren't what you had in mind.

At Alila Villas Soori, the resort's spa uses "age-old beauty recipes that feature the curative benefits of fresh, natural ingredients." And with its hair masque, this means chopping up a pile of avocado then rubbing it into your scalp.

A martini is on hand to calm the nerves when you mistake yourself in the mirror for Heath Ledger's portrayal of the Joker. Happily, it all washes out, leaving your hair silky soft – and back to its original colour. 968,000 rupiah (£65).
