A blow dry at a high-end salon might set you back around ?70.
And even then, only a handful of people would be willing to fork out for styling that lasts only a few days.
But at the most exclusive department store in the world, clients can expect to pay up to ?320 for a very temporary hair makeover.
Urban Retreat at Harrods has launched The World's Most Expensive Blowdry.
Created to launch the arrival of haircare brand Truffle by Fuente, the treatment includes a shampoo and condition, a revolutionary 'self-thinking' product which uses White Truffle Skin, diamond dust and meteorite extracts.
The inGREdients are said to react 'intelligently' to the specific needs of each individual hair type, restoring locks to their finest possible condition, whatever the extent of damage.
Afterwards, professional stylist Flavian Abbas will tease, twirl and boost roots for a blow dry that will leave your hair looking silken, shining with health and feeling light as air.
No doubt the Duchess of Cambridge, who often spends hours in King's Road salon Richard Ward to perfect her tresses, will be keen to test the treatment out.
The package includes bottles of Truffle Shampoo and Truffle Conditioner, retailing at ?275, to take home, and a hot stone cranial massage.
And after spending ?320, you'd need to feel as relaxed as possible.
