Does Hair Relaxer Cause Cancer?
At this time, no court or medical authority has ruled that chemical hair relaxers cause cancer. However, scientific studies and ongoing lawsuits are examining whether long-term, frequent use of certain chemical hair relaxers may be associated with increased cancer risk. Manufacturers dispute these claims, and research is ongoing.
Concerns about hair relaxers and cancers have been raised by research, government warnings, and lawsuits. Some of these concerns focus on whether relaxers may be associated with increased cancer in certain users. Research on this topic is still ongoing, and no court has reached a verdict in those lawsuits.
Read on to learn more about what scientists and lawyers say about chemical hair relaxers and cancer.

What Hair Relaxer Cancer Studies Say
There’s no shortage of research when it comes to the long-term effects of chemical hair treatments. This includes commercially available relaxers and straighteners.
That said, before we get too deep into the associations indicated, remember they are still only associations. This means the numbers might show statistical links, but they don’t prove that any products cause cancer.
So, when people inevitably ask, “Does hair relaxer cause cancer?” The answer is complex. Right now, it might be best to say there’s a lot of data and evidence, but science is still sorting things out. On top of that, courts haven’t issued any final determination of causation in any of these cases.
So, with that in mind, let’s look at some of the major associations.
Uterine Cancer
A higher rate of uterine cancer was found in women using straighteners frequently.
In a 2022 study by an NIH-affiliated body, more than 4 uses per year showed about twice the cancer risk. This represents a significant statistical difference.
It’s important to interpret these findings carefully. While these findings do show an association, that association isn’t proof. There is no definitive proof that these chemicals cause cancer.
This distinction is critical when you consider how long uterine cancer takes to develop. People most at-risk use these products for years. Significant portions of their lives, in some cases.
Ovarian Cancer
Separate research into hair product cancer risk shows higher rates of ovarian cancer. Again, this research focused on long-time and frequent users. The frequency of use is so important in hair relaxer cancer lawsuits.
If long-term use cannot be documented, it may make a claim more difficult to pursue. While there’s no proof that hair relaxers cause cancer, the associations can be troubling. Showing that an individual used chemical hair relaxers, then later developed ovarian cancer, may strengthen the case.
These claims often rely on the statistical associations identified in existing research. It builds on the progress of others and may support your eligibility.
Endometrial Cancer
Endometrial cancer is one of the most devastating reproductive cancers. It starts in the lining of the uterus and progresses. Hormone balance is a major factor, with estrogen exposure in particular.
According to the American Cancer Society, higher lifetime estrogen exposure could mean a higher risk of endometrial cancer. It’s one of the major risk factors.
There are other factors that could increase risk even more, including:
- Early menstruation
- Late menopause
- Having fewer or no pregnancies
Some of the lawsuits rely on hormone-related research. Some lawsuits reference this research when arguing that certain chemical exposures may play a role over time.
Claiming damages in endometrial cancer cases can be complex. Some claims involve partial or full hysterectomies, though litigation is still ongoing. In addition to the financial component, it can be a powerful emotional blow for many women.
What Do These Studies Prove?
Most of all, these studies show statistical associations between long-term relaxer use and specific cancers. What they don’t do is prove relaxers cause cancer. They also don’t identify any particular product as causing any one person’s diagnosis.
It may be years before the courts make any final order on medical causation. In the meantime, there is still ongoing research. Research and data collection help move the legal cases forward.
About Hair Relaxers
Before we get too far into how the lawsuits work, let’s clear up some terminology. When we say “hair relaxers”, we’re casting a wide net. We mean most chemical products meant to straighten tightly curled hair.
Usually, this happens by breaking down the proteins in the hair. There are two main categories of chemical hair relaxers:
- Lye-based relaxers: This category is limited to products that use sodium hydroxide as the active straightener. This distinction is crucial.
- Non-lye relaxers: Non-lye relaxers encompass all relaxers that don’t use lye. No matter how it happens.
Different people have different preferences for their hair. For some, convenience is important. Others might make styling options their priority.
The lawsuits are focused on long-term, multi-year exposure. That’s the most important core element of any case.
You may be wondering, can hair relaxer cause cancer? But remember the limitations. As of the time of writing, early 2026, everything still revolves around possible links. Correlation isn’t causation. Since this still hasn’t been proven in court, ongoing research is critical.
What Is the Hair Relaxer Lawsuit About?
Most hair relaxer lawsuits focus on the lack of manufacturer warnings. The claim is that certain producers didn’t tell people about the health risks of long-term use. Many of these cases reference the NIH link between frequent use and the risk of uterine cancer.
These cases are often part of broader, federal tort actions. Since there are so many injured parties, from so many districts, the individual lawsuits all get combined. This is known as multidistrict litigation, or just MDL.
Marketing Related Allegations
Many of the lawsuits are aimed at marketing practices. Some discussions focus on the disproportionate impact hair relaxer use may have on Black women.
Some lawsuits and surveys reference social and professional pressures that may have influenced relaxer use among some Black women. Some reports also suggest these pressures may begin influencing grooming choices at younger ages.
Some individuals have also reported workplace expectations around hair appearance. Black women report being frequently told that their natural hair looks “unprofessional”. In some reported cases, workplace policies or expectations have described natural hairstyles as “unkempt” or “unprofessional.”
These reported pressures are sometimes cited as a reason some individuals choose long-term relaxer use. Survey data shows 66% of Black and Brown girls experienced hair discrimination in white-majority settings.
Who Can File a Hair Relaxer Cancer Lawsuit?
Generally speaking, there are two big criteria that need to be true for an individual to potentially be eligible.
First, they will be people who have regularly used chemical hair straighteners for a long time. Often, periods of several or even many years. Second, they either have a diagnosis for one of a few specific cancers or they’ve had surgery to treat fibroids.
These are the individuals most commonly exploring potential links between their relaxer use and cancer. Most lawsuits focus on the potential link between cancer and product use.
They don’t aim to legally determine the answer to “Do chemical hair straighteners cause cancer?” Courts have not ruled that relaxers cause cancer. Most cases are still developing.
Many individuals have come forward to share their experiences. Their bravery and medical information help ongoing litigation.
Even when all the conditions are met, eligibility isn’t promised. Some individuals may still not qualify. Every situation is unique, though. Eligibility is based on specific facts, not on broad assumptions.

Qualifying Criteria
Qualifying use of specific products and medical history play a big role in eligibility. The most effective claims are those built on long-term or frequent exposure. If you meet some basic criteria, you or your loved one might be eligible.
One common qualifier is first, having used chemical hair relaxers regularly over the course of several years. Then, being subsequently diagnosed with one or more of the following conditions:
- Uterine Cancer
- Ovarian Cancer
- Endometrial Cancer
Or, if you needed a hysterectomy surgery for uterine fibroids.
Be ready to bring all the evidence you can to support your claim. This means any paperwork you may have. A proof of diagnosis, medical or surgical records, or any resources that show long-term chemical relaxer use. You should be gathering salon records, receipts, product photos, and timeline documentation.
If you’re asking, ‘Do relaxers cause cancer?’ It’s important to focus on the current limits of available evidence. Cases like these typically focus on eligibility to pursue claims. They usually don’t revolve around proven medical diagnoses or conclusions.
What Could a Hair Relaxer Settlement Look Like?
Settlement Disclaimer: Past results do not guarantee future outcomes. Each case is unique, and compensation depends on individual circumstances.
It’s important to remember there are no guaranteed settlement amounts in hair relaxer cases. There are many lawsuits in process across the country, and most are still in their early stages.
Outcomes are never guaranteed, and when settlements are reached, they can vary wildly. If compensation is awarded, the amount will be the result of several factors. Awards depend on the type of cancer, treatment already received, potential long-term effects, and more. A big factor is how well the product use history can be documented.
