Paris Hilton has found herself in yet another hairy situation.

Hairtech International is suing the socialite for $35 million for fraud and breach of contract, our pals over at PopEater report. The hair extension company alleges Hilton broke the conditions of her contract to wear and promote their product when she wore a competitor's extensions. Hairtech also alleges that Hilton's partying is contrary to their marketing campaign.

The suit claims Hilton, 29, was "seen in magazines and on television not wearing [their] hair extensions and was in fact wearing competitors' hair extension products."

The filing also states the heiress missed a launch party in 2007 because she was serving jail time. The company says they invited more than 600 hair extension professionals to the party and when Hilton didn't show up, her absence ended up costing the company $6.6 million in potential revenue. Hilton spent 23 days in jail after getting caught driving on a suspended license while on probation.

Hilton's publicist, Dawn Miller, has yet to make a comment on the lawsuit.
