Now that’s a mouthful – or a headful to grasp – Kate Hudson has been sued by a California company for exposing trade secrets relating to hair care.

Like many a celebrity before her, Kate Hudson has turned to ventures other than acting, that is to her own line of hair-care products. In order to offer fans and anyone else interested the eco-friendly shampoos and conditioners, Hudson teamed up with her longtime stylist David Babaii.

The line, titled David Babaii for WildAid, was launched in June and claimed to have one very unique and previously unthought-of ingredient: volcanic ash.

It is nearly the end of August and troubles have arisen for Kate Hudson’s business project. A California firm called 220 Laboratories Inc recently filed a lawsuit against David Babaii for WildAid and its two partners.

The firm claims the idea to include volcanic ash in hair-care products is its own, shared with Babaii within the confidential context of an “oral contract,” reports Reuters. Papers filed Friday in Los Angeles Superior Court state that 220 Laboratories first presented the idea of using volcanic ash from the Vanuatu Islands of the South Pacific to the celeb stylist in 2006.

220 Laboratories accuses Hudson, Babaii and Universal of misappropriation of trade secrets, fraud and breach of contract. The plaintiffs are seeking unspecified damages, which include attorneys’ fees, as well as an injunction against David Babaii for WildAid to use its “trade secrets.”

Hudson and Babaii responded through representatives on Tuesday, calling the lawsuit “without merit.” The 29-year-old actress’s spokesman, Brad Cafarelli, told Reuters in an e-mail that his client “does not know the plaintiffs and has never met with them or spoken with them.”

Ten percent of profits made by David Babaii for WildAid are to be donated to WildAid, a wildlife conservation group.
