Kim Kardashian and sisters Khloé and Kourtney have beautiful hair, but do they wash their locks with money? That's the only justification we can think of for a $12,000 hair allowance!

According to a lawsuit filed by the Revenue Resource Group, the company currently suing the Kardashians for breach of contract after they backed out of a deal to promote a prepaid credit card, Kim Kardashian demanded that her hair stylist be flown to New York City for the card's launch party, at a cost of $12,000. The family later agreed to a more modest budget of $7,000 for hair and makeup expenses for all three sisters, still a fair chunk of change to do some curls and three sets of smoky eyes.

"I imagine at least some of that 12K was for travel and accommodations but that still leaves about $10,000 for hair. You could spend that if you're doing a beluga caviar treatment and then hiring elves by the hour to dry the hair strand by strand," explains Jackie Cascarano, creative director of luxury hair retailer Lock & Mane.

The $7,000 hair-and-makeup fee is just a pittance of the $500,000 in out-of-pocket expenses the company claims it incurred to launch the Kardashian Kard.

Revenue Resources alleges they spent $5,000 for Khloé to fly first-class to the party, $1,900 for an Escalade to shuttle them around town and $6,360 for bottle service at the party. And after all that, the girls couldn't even be bothered to stay for the whole event.

The sisters were contractually obligated to stay at the party for at least three hours, but Nathan Miller, an attorney representing Revenue Resource Group, claims they left after just 55 minutes. He had to call their mother, Kris Jenner, to get them back to the party.

And that $500,000 is only the tip of the iceberg, according to the lawsuit. Revenue Resource Group says the family owes it $75 million in lost revenue!

"It's $75 million and nothing less than $75 million," Miller told CNNMoney. "With the Kardashians' star power, the amount of cards they would have sold would have been off the chart."
