Status of Hair Dye Bladder Cancer Lawsuits Outlined for Court

At least 15 hair dye lawsuits have been filed in California state court by salon workers diagnosed with bladder cancer and other injuries.

As a growing number of hairdressers, cosmetologists and other salon workers continue to file bladder cancer lawsuits against hair dye manufacturers, indicating that they were not adequately warned about the risks associated with long-term exposure to the products, lawyers will meet next week for an initial status conference with the judge presiding over most of the litigation.

Although professional hair dye and coloring products have been widely marketed as safe for salon workers, research has found that routine exposure to toxic chemicals in the products can substantially increase the risk of bladder cancer, even when gloves and other recommended precautions are followed.

Since hair dye chemicals can be absorbed through the skin or inhaled, cosmetologists are often exposed to hair dyes multiple times per day over the course of their careers, which could last decades, making occupational exposure a significant risk factor for bladder cancer among those in the salon industry.

L’Oreal, Paul Mitchell, Redken, Clairol and cosmetic manufacturers now face dozens of hair dye bladder cancer lawsuits, each raising similar allegations that the companies knew or should have known about the risks, yet chose not to warn salon professionals about steps that could have been taken to avoid the development of cancer from hair dye exposure.

One of the first hair dye lawsuits was filed by Hector Corvera in the Superior Court of California for Los Angeles County in January, indicating he had developed bladder cancer following 42 years using professional hair dye products during his work.

According to recent court documents, at least 14 similar claims have been filed after Corvera’s in the same California court, which have all been consolidated before Judge Samantha Jessner for coordinated pretrial proceedings. As more cosmetologists and salon workers learn of the links between hair dye and bladder cancer, that number is expected to continue to grow.

In a Notice of Court Order (PDF) issued on June 26, Judge Jessner indicated that Corvera’s claim was designated the lead case for the litigation. The court also moved up the date of the initial status conference for Corvera’s lawsuit from August 8, 2025 to July 21, 2025.

In advance of that meeting on Monday, lawyers submitted a joint statement (PDF) on June 15, to bring the court up to speed on the status of the litigation and the topics to be discussed at the hearing.

Plaintiffs, defendants and the court are expected to discuss the preservation of evidence and protective orders, in addition to when the current stay pausing the litigation should be lifted, as well as motions and pleadings likely to be filed early in the litigation.

To help gauge how juries may respond to certain evidence and testimony that may be repeated throughout the litigation, it is expected that Judge Jessner may prepare the Corvera lawsuit as a bellwether case. While the outcome of any early bellwether trials would not be binding on other current or future cases, it could help the parties reach a hair dye bladder cancer settlement agreement, avoiding the need for every claim to go through a long and expensive trial process.

Hair dye bladder cancer lawyers continue to investigate cases for individuals diagnosed with bladder cancer following long-term use of permanent or semi-permanent hair dye products. Individuals who believe their cancer may be linked to chemical exposure from hair dye are encouraged to request a free consultation to see if they may qualify for a bladder cancer lawsuit settlement.
