You can't go slapping Tyra Banks' name willy-nilly on wigs -- not without her slapping back with a massive lawsuit for 10 million dollars ... TMZ has learned.
Tyra just filed a lawsuit in L.A. County against 10 companies that make wigs ... and in the suit she claims they're all biting her "name, photograph, image, and identity" -- as well as her trademarks.
We know squat about wigs ... but some quick research revealed several of the companies do have Tyra's photos and Tyra inspired wigs on their websites.
A few examples: The Yaki straight[Tyra-Banks style] wig, the Tyra Banks custom lace wig #046, and our fave -- the Tyra Banks inspired human hair wig. We're guessing it's not actually TB's hair you're buying ... although it does cost $300!
Several pages of the lawsuit are spent on spelling out how valuable her trademark is because she's a huge star ... and to prove it her IMDB profile -- all 11 pages -- are attached to the suit as Exhibit A.
To be fair, the suit also refers to Tyra as a "former supermodel."
TB is suing for an injunction to stop the sale of the infringing products -- and at least $10 million in damages.
Fun fact: Tyra's first acting credit was Jackie Ames on "The Fresh Prince of Bel-Air" in 1995. Thanks Exhibit A.
