For those who have everything: Out-of-this-world hair

Harrods' Urban Retreat spa in London probably isn't bluffing when it brags about offering "the world's most expensive blow-dry" ($500). For that price, a stylist will lather your hair with Truffle by Fuente, a shampoo containing "the skin of white truffle, pure diamond dust, and meteorite dust from space." The meteor dust makes for a "self-thinking" shampoo that intelligently restores hair to top condition, Fuente says. Since Harrods lets you keep the $430 shampoo set, maybe an extra $70 for the "hot stone cranial massage" and "signature Harrods blow-dry" isn't so bad. Source: The Stir
