Hallstar secures 15-year ban for former executive in Proscien dispute

By Tom Whitfield

Robert Hu has agreed to a 15-year ban on working for, owning or otherwise assisting the rival business Proscien and its affiliates. The former Hallstar Beauty & Personal Care president admitted breaching confidentiality and non-compete agreements as part of a comprehensive settlement. The US District Court for the Northern District of Illinois resolved Hallstar’s claims against him through that settlement, covering misappropriation of trade secrets, breach of contract, tortious interference and breach of fiduciary duty.

Hu admitted using information and knowledge gained during his Hallstar employment to help develop competing product lines. Those lines were marketed as Proshield, Prolive, Proactive and Prosenteur. He helped develop them while Proscien was being formed and grown. The announcement names the product lines but does not specify which formulations, technical specifications or trade secrets were involved.

He also admitted working for Proscien to build distributor relationships in China and South Korea. He used contacts developed while at Hallstar. Hu acknowledged that Hallstar suffered damages. The announcement did not quantify those damages or disclose any settlement payment.

The terms imposed on Hu

Hu joined Hallstar in 2012 as its R&D vice president. He later became president and chief technology officer of Hallstar Beauty. He departed in 2021.

The settlement bars Hu from accepting employment with Proscien or its affiliates. It also bars him from holding an ownership interest or otherwise assisting Proscien or its affiliates for 15 years. A broader two-year non-compete applies across the beauty products industry.

The consent judgment can be enforced internationally through binding arbitration if Hu violates it again, while Hallstar continues to pursue separate claims against Proscien and founder Jean-Claude Pierre. That mechanism addresses future conduct by Hu. It does not determine the claims against Proscien or Pierre.

What does the settlement change for salon professionals?

The reported settlement terms do not impose a product recall, formulation change or supply restriction, and they announce no change to products moving through distribution channels. Their immediate effect is an enforceable restriction on a former senior executive. For salons and distributors, the practical effect remains unquantified. The settlement gives no sales figure, market-share data or remedy amount. It also leaves Hallstar’s continuing case against Proscien and Pierre unresolved. The restriction binds Hu. It does not bind Proscien.

Hu’s admission identifies the conduct now resolved against him. It does not settle the wider corporate litigation. Hallstar has said it intends to press those claims through to a conclusion.

Hallstar’s claims and the French ruling

Hallstar continues to pursue Proscien and Pierre over the same underlying conduct. In November 2025, a French court separately ruled in Hallstar’s favour against Proscien in a case concerning misleading commercial practices and website non-compliance with certain French regulations.

The French judgment is not the Illinois consent judgment. It addresses a different set of issues. It does not quantify damages, determine the American claims or end the US litigation. The announcement does not specify any remedy that followed.

The limits of Hallstar’s case

A Hallstar spokeswoman said: “This judgment reflects a clear and formal acknowledgment of wrongdoing and holds those responsible accountable.” The statement addresses Hu’s admission. It should not be read as a resolution of the claims directed at Proscien and Pierre.

She also called Hallstar’s decades-long innovation record exceptional. She added: “Our established product development team, reliable global supply chain, regulatory and quality compliance expertise—these are advantages that an unproven or newer entrant cannot match.” These remain company assertions. The announcement supplies no comparative performance or supply-chain data to test them.

Hallstar also said protecting confidential information, trade secrets, and the integrity of distributor and customer relationships worldwide remained a top priority. It said it would continue taking appropriate action to defend the business. The unresolved issues include the scope of protected information, the damage calculation and the remedies still in dispute. None is settled by Hu’s consent judgment.

For salon professionals, the continuing US case is the next material development. Any ruling will bear on Hallstar’s claims against Proscien and Pierre. The 15-year restriction on Hu does not decide those claims.
