The priciest Christmas party prep ever? The £200 tan, the £100 pedi and the £1000 hairdo; the recession-proof beauty industry starts prepping for the party season. If you're even looking at the price tag, these super luxe new treatments probably aren't for you, because as great as they are, they're not quite as great as the bill they come with. Having watched the evolution of the credit crunch-proof beauty buyer, the luxury salons are upping their game, and prices, just in time for the party season. Swarovski pedicure anyone? Diamond tan perhaps? Celebrity colour and blow-dry to go? The Swarovski pedicure at Michaeljohn The Spa , Motcomb Street (the new mini sister-salon to their highbrow Mayfair HQ) might set you back £100 but it's already a hit. No wonder. Their pedicure chairs - think camel leather thrones with inbuilt massage settings - are more superior than most, and with hundreds of painstakingly placed crystals upon your toes this pedicure turns any pair of feet into something suddenly party-worthy. Or, if you want a tan that's really on the money (like, all of it) then head to Selfridges, where this years theme is "a Christmas like no other," and the tanning menu includes The Diamond Tan by St. Tropez . At £200 it is the most expensive tanning treatment in the world to date. But who's talking expenses? The Diamond Tan has already become the London girl's best friend; St. Tropez are taking bookings before the tan even launches next week and it's expected to be fully booked during its limited lifetime. We have to say there is something rather dazzling about the way this bronzing treatment promises to make our skin glow with real diamond dust. Plus you'll shimmer off into the distance with a St. Tropez atomiser full of said diamond dust to top up your glow long after the tan has faded. The Josh Wood Atelier, Liberty London However. it's our hair budget that seems to be the most recession-proof of all; just ask colourist to the A-listers, Josh Wood, who recently opened up his second sleek Atelier on the third floor of Liberty London . Here you can book in to see the genius himself (Wood makes an appearance every Wednesday) for a full head of highlights, and finish with a blow-dry, cut and more bangs for your buck with stylist George Northwood (that's if his regular clients Alexa Chung and Rose Huntington-Whitely aren't already in his chair for his signature fashion cut) for a cool £1000.
