What is the hair relaxer lawsuit?

The hair relaxer litigation involves lawsuits alleging that long-term or repeated use of certain chemical hair relaxers or straightening products contributed to serious reproductive cancers or other injuries.

Plaintiffs generally allege that manufacturers:

• Sold products containing potentially harmful chemicals.
• Failed to adequately test or warn about alleged health risks.
• Marketed products despite alleged safety concerns.
• Designed or formulated products in ways that created unreasonable risks.

The defendants dispute these allegations.

The lawsuits do not establish that every hair relaxer product causes cancer or that every person who used a relaxer has a legal claim.

Is there a hair relaxer MDL?

Yes.

Federal hair relaxer cases are centralized in:

In re: Hair Relaxer Marketing, Sales Practices, and Products Liability Litigation

MDL No. 3060

U.S. District Court for the Northern District of Illinois

The multidistrict litigation is assigned to U.S. District Judge Mary M. Rowland. The JPML's August 3, 2026 statistics list 11,779 pending actions and 16,199 total actions in MDL 3060.

That makes it one of the largest active federal product-liability MDLs.

Why are people filing hair relaxer lawsuits?

Plaintiffs generally allege that they used chemical hair relaxers or straighteners over time and were later diagnosed with serious reproductive cancers or other conditions.

Depending on the individual case, claims may involve legal theories such as:

• Product liability
• Failure to warn
• Defective design
• Negligence
• Breach of warranty
• Other state-law claims

Whether a particular product caused an individual's injury remains a central factual and scientific issue in the litigation.

What cancers are alleged in the hair relaxer litigation?

Claims in the litigation have focused primarily on alleged reproductive cancers, including:

• Uterine cancer
• Endometrial cancer
• Ovarian cancer

Some plaintiffs have also alleged other reproductive health injuries.

The specific injury categories permitted or disputed in the litigation may change as the court resolves scientific and legal issues.

A diagnosis alone does not establish that a hair relaxer caused the condition.

What does the research say about hair relaxers and uterine cancer?

The evidence is still developing.

A 2022 National Institutes of Health study using data from the Sister Study reported that women who used chemical hair straightening products had a higher observed rate of uterine cancer than women who did not report using them. The association was stronger among women who reported frequent use.

NIH emphasized that the study identified an association, not proof that hair straighteners caused uterine cancer.

That distinction matters.

Observational studies can identify patterns between an exposure and a disease, but they cannot by themselves establish legal or medical causation for an individual person.

Is the scientific evidence settled?

No.

Research findings are not entirely uniform.

For example, a 2023 study involving participants in the Black Women's Health Study reported an association between long-term chemical hair relaxer use and uterine cancer among postmenopausal women.

However, a 2025 systematic review of the epidemiologic literature concluded that the overall evidence it examined did not demonstrate an increased risk of breast, ovarian, or uterine cancer from hair relaxers, while also noting limitations in the available studies.

That disagreement illustrates why general causation remains an important issue in the litigation.

BenefitKarma should not characterize the relationship as medically proven when credible scientific literature remains under evaluation.

Why are chemical ingredients part of the discussion?

Hair relaxers and straightening products can contain or involve exposure to many different chemicals, depending on the product.

Researchers have examined possible exposure to substances with endocrine-disrupting or other biologic properties.

Separately, the FDA has warned that some hair smoothing or straightening products release formaldehyde gas when heated. Formaldehyde is classified as a human carcinogen.

However, hair smoothing products that release formaldehyde are not necessarily the same products or exposures involved in every hair relaxer lawsuit.

It is important not to assume that formaldehyde is the alleged cause in every MDL 3060 case.

Who has been named in hair relaxer lawsuits?

The litigation involves multiple manufacturers and companies associated with chemical hair relaxer products.

The precise defendants differ by case and product.

Rather than relying on marketing pages for a static brand list, the most reliable source for current defendants is the federal MDL docket and individual complaints because parties can be added, dismissed, or otherwise change as litigation progresses.

Is the hair relaxer lawsuit a class action?

No.

MDL 3060 is a multidistrict litigation, not a class action.

In an MDL:

• Individual federal lawsuits remain separate claims.
• Common pretrial issues are coordinated before one federal judge.
• Discovery can be managed more efficiently.
• Scientific and expert issues may be addressed across groups of cases.

Each plaintiff still has an individual medical history, product-use history, alleged injury, and damages.

There is no automatic equal payout for everyone in an MDL.

What is happening in MDL 3060 now?

The litigation remains active.

The Northern District of Illinois maintains the official MDL 3060 docket and case-management materials, and the JPML continued to list the proceeding as active in August 2026.

The litigation has involved coordinated discovery, expert issues, plaintiff-specific case development, and preparation of representative cases for further proceedings.

Because court schedules can change, current status should always be checked against the official federal docket rather than older news articles or law-firm updates.

What is a bellwether case?

A bellwether case is an individual lawsuit selected from a larger group of similar cases for more intensive discovery or trial preparation.

Bellwether cases can help:

• Test legal arguments.
• Evaluate scientific evidence.
• Show how juries may react to different fact patterns.
• Help parties assess litigation risk.

A bellwether result does not automatically determine the outcome of every other case in the MDL.

Who may be affected by the hair relaxer litigation?

Potential claims generally involve people who:

• Used chemical hair relaxer or straightening products.
• Used the products repeatedly or over an extended period.
• Were later diagnosed with a qualifying injury alleged in the litigation.
• Have medical and product-use evidence supporting their history.
• Meet applicable filing deadlines.

The exact criteria depend on the individual claim and current litigation requirements.

Using hair relaxer products alone does not establish a legal claim.

What evidence may matter in a hair relaxer case?

Potentially relevant evidence can include:

• Medical records
• Pathology reports
• Cancer diagnosis records
• Surgical records
• Oncology records
• Product purchase records
• Photographs of products
• Salon records
• Statements about frequency and duration of use
• Brand and product names
• Family or witness statements
• Other possible cancer risk factors

Because product use may span many years, reconstructing exposure history can be an important part of the case.

Do you need receipts from years ago?

Not necessarily.

Receipts or purchase records can be useful, but they are not always available after years of product use.

Other evidence may help establish product history, including:

• Photographs
• Salon records
• Loyalty or purchase histories
• Statements from family members
• Statements from hairstylists
• Consistent recollection of particular brands or products

The evidence required depends on the individual case.

Has the hair relaxer lawsuit settled?

There is no single global settlement resolving MDL 3060 as of August 2026.

The JPML continues to list thousands of pending cases in the federal proceeding.

Individual claims may be dismissed, settled, tried, or otherwise resolved without producing a universal settlement for every plaintiff.

Consumers should be cautious about websites publishing definitive "hair relaxer settlement amounts" before an actual settlement framework exists.

How much is a hair relaxer lawsuit worth?

There is no established universal payout.

Potential compensation can depend on factors such as:

• Type of cancer or injury
• Severity of the condition
• Medical treatment
• Surgery
• Prognosis
• Lost income
• Medical expenses
• Product-use history
• Strength of causation evidence
• Applicable state law
• Outcome of the litigation

Online estimates are speculative unless they are tied to a documented settlement or verdict.

Is there a deadline to file a hair relaxer lawsuit?

Yes.

Product liability claims are subject to statutes of limitation.

The applicable deadline may depend on:

• The state whose law applies.
• When the condition was diagnosed.
• When the plaintiff learned or reasonably could have learned of the alleged connection between product use and the injury.
• Other individual circumstances.

Participation in an MDL does not eliminate filing deadlines.

Common misconceptions

Myth: Scientists have proven that chemical hair relaxers cause uterine cancer.

Reality: Multiple observational studies have reported associations between chemical hair straightener or relaxer use and uterine cancer risk, but association is not the same as proof of causation. Other scientific reviews have reached more cautious conclusions, and causation remains contested in the litigation.

Why this matters

Hair relaxer litigation sits at the intersection of consumer safety, cancer research, and a long history of products marketed heavily to Black women.

That makes accuracy particularly important.

The strongest evidence supports saying that researchers have identified concerning associations that deserve continued study—not that every product has been proven to cause cancer.

At the same time, MDL 3060 is a large, active federal litigation in which thousands of plaintiffs are asking courts to determine whether specific products caused legally compensable injuries.
