Court records show Los Angeles Superior Court Judge Gregory Alarcon agreed with Hilton's attorneys that Hairtech International Inc.'s lawsuit did not properly plead several key claims, including fraud.
Alarcon's ruling also removes Hilton's father, Rick Hilton, from the case and strikes numerous references to the 29-year-old wearing competitor's hair extensions.
Hairtech sued the reality TV star in August, and she has since countersued claiming the company owes her $1.7 million.
Hairtech's attorney, Chris Brainard, did not immediately return a phone message.
