L’Oréal has been ordered to stop making and selling nine of its hair care products, including treatments for salon brands Matrix, Redken and L’Oréal Professionnel.
The permanent injunction is only applicable to the US market and has been enforced after a jury found the French cosmetics producer liable of infringing patents held by indie brand Olaplex.
The two year-long case came to an end last week after Olaplex accused L’Oréal of stealing trade secrets during takeover talks.
Officially launched in June 2014, Olaplex quickly gained popularity among stylists and celebrities, including Kim Kardashian and Drew Barrymore, for its patented technology that aims to protect hair during bleach treatments.
The judge first prohibited the 110-year-old company from selling the products in April to prevent anymore financial damage to Olaplex during the legal proceedings.
L’Oréal filed an appeal on Friday 16 August.
