Latest Optimum Hair Relaxer Lawsuit Developments
May 2026
- May 17, 2026 – A new product-liability action naming L’Oréal USA and SoftSheen-Carson was filed directly in the Northern District of Illinois as a member case of the federal Hair Relaxer Marketing, Sales Practices, and Products Liability Litigation, MDL No. 3060, confirming that new claims continued entering the coordinated proceeding in 2026 [1]
February 2023
- February 6, 2023 – The Judicial Panel on Multidistrict Litigation centralized federal lawsuits involving chemical hair relaxers and straighteners in MDL No. 3060, In re: Hair Relaxer Marketing, Sales Practices, and Products Liability Litigation, for coordinated pretrial proceedings [2]
October 2022
- October 17, 2022 – NIH reported that women who used chemical hair-straightening products more than four times during the previous year were more than twice as likely to develop uterine cancer during follow-up as women who reported no use. Researchers emphasized that more research was needed and did not identify specific brands or ingredients [3]
What Is Optimum Hair Relaxer?
Optimum is a hair-relaxer product line historically marketed through SoftSheen-Carson.
Federal trade records document that L’Oréal acquired Soft Sheen Products in 1998 and later combined its hair-care business with Carson. The Federal Trade Commission described Optimum Care as one of Soft Sheen’s adult women’s hair-relaxer brands [4]
L’Oréal has also acknowledged that plaintiffs in hair-relaxer litigation identify SoftSheen-Carson product lines including Dark & Lovely and Optimum.
What Are Hair Relaxers?
Chemical relaxers alter the structure of tightly curled or coiled hair so that it becomes straighter.
Different formulations may contain different active and inactive ingredients, and formulations can change over time. A consumer’s actual product packaging or ingredient list is therefore more reliable than making broad assumptions about every Optimum product.
Long-term exposure history can be important in litigation because many plaintiffs allege repeated product use over years or decades.
What Did the NIH Hair-Straightener Study Find?
The 2022 NIH-supported study followed 33,497 U.S. women ages 35 through 74 who participated in the Sister Study.
Researchers followed participants for almost 11 years and documented 378 uterine-cancer diagnoses. Women who reported using straightening products more than four times during the previous year had more than twice the observed risk of developing uterine cancer compared with women who reported no straightener use [5]
Researchers estimated that approximately 1.64% of women who never used straighteners would develop uterine cancer by age 70 compared with approximately 4.05% of frequent users.
Does the Study Prove Optimum Hair Relaxer Causes Uterine Cancer?
No. The study found an epidemiologic association between chemical hair-straightener use and uterine-cancer incidence, but it did not establish that Optimum or another particular brand caused an individual cancer.
NIH specifically reported that researchers did not collect information about brands or ingredients used by participants. The authors said additional research was needed to confirm the findings and identify chemicals that might contribute to the observed association.
Individual litigation therefore requires evidence beyond the existence of the study, including product history, diagnosis, exposure duration, medical evidence, and expert causation analysis.
Why Is Frequent Use Important?
The strongest association in the NIH study involved women who reported using straightening products more than four times during the previous year.
Frequency may matter because repeated application can increase cumulative exposure to chemicals contained in a product. However, the study did not establish a particular number of applications that automatically causes cancer.
Attorneys reviewing an Optimum claim may ask when use began, how often the product was applied, whether treatments occurred at home or in a salon, and how many years use continued.
Why Are Uterine and Endometrial Cancer Central to the Litigation?
Uterine cancer is the most common cancer of the female reproductive system, and endometrial cancer begins in the lining of the uterus.
The 2022 Sister Study was the first epidemiologic study specifically examining straightener use and incident uterine cancer, according to NIH.
That research became an important scientific basis for subsequent product-liability allegations, although defendants dispute that hair relaxer products caused plaintiffs’ cancers.
Are Ovarian Cancer Claims Also Being Filed?
Yes. The broader federal hair-relaxer litigation includes plaintiffs alleging ovarian cancer and other gynecologic cancers in addition to uterine or endometrial cancer.
The scientific evidence supporting each diagnosis is not identical. A diagnosis should therefore be evaluated independently rather than treating all reproductive conditions as equally supported by the same study.
Medical records, pathology, treatment history, product exposure, age, family history, and other potential risk factors can affect causation analysis.
What About Breast Cancer, Fibroids, and Endometriosis?
Research has examined possible associations between hair-product use and several hormone-related or reproductive conditions, but the evidence varies by condition.
The 2022 NIH uterine-cancer study should not be cited as proof that Optimum causes breast cancer, endometriosis, infertility, fibroids, or every other condition historically alleged on hair-relaxer pages.
A legal claim involving a diagnosis outside the cancers being actively evaluated in the federal litigation requires a diagnosis-specific scientific and legal assessment.
What Chemicals Are Researchers Studying?
NIH researchers noted that substances previously detected in some straightening products have included parabens, bisphenol A, certain metals, and formaldehyde.
The study did not determine which chemical or combination of chemicals produced the observed uterine-cancer association.
It is therefore inaccurate to claim that every Optimum formulation contains DEHP, formaldehyde, or another particular chemical without product-specific testing or ingredient documentation.
Why Can Scalp Exposure Matter?
Hair relaxers are applied directly to hair and close to the scalp, creating an opportunity for chemical contact with skin.
NIH researchers noted that absorption could potentially be increased when straightening products cause burns or lesions on the scalp.
This is one proposed exposure consideration rather than proof that a scalp burn caused cancer in a particular consumer.
What Do Optimum Hair Relaxer Lawsuits Allege?
Plaintiffs in the broader hair-relaxer litigation generally allege that manufacturers designed, manufactured, marketed, and sold chemical straighteners without adequate warnings concerning alleged long-term health risks.
Claims may include defective design, failure to warn, negligence, breach of warranty, misrepresentation, or other theories depending on state law.
These allegations have not been established as facts for every product or plaintiff.
What Is L’Oréal’s Position?
L’Oréal disputes the hair-relaxer allegations and has publicly stated that it is confident in the safety of SoftSheen-Carson products.
The company argues that the NIH study did not establish a causal relationship between its products and plaintiffs’ claimed health conditions and emphasizes the researchers’ statement that additional research is warranted [6]
Those defenses will be evaluated through the litigation process along with plaintiffs’ scientific and product-liability evidence.
What Is MDL No. 3060?
MDL No. 3060 is the federal proceeding titled In re: Hair Relaxer Marketing, Sales Practices, and Products Liability Litigation.
The Judicial Panel on Multidistrict Litigation centralized cases in the U.S. District Court for the Northern District of Illinois before Judge Mary M. Rowland so common pretrial issues could be handled efficiently.
An MDL is not the same as a class action. Each plaintiff generally retains an individual claim, medical history, exposure evidence, alleged damages, and potential case value.
Is Optimum Specifically Involved in Hair Relaxer Litigation?
Yes. Optimum has been identified in hair-relaxer complaints involving SoftSheen-Carson and L’Oréal.
During the original MDL proceedings, L’Oréal acknowledged that plaintiffs identified two SoftSheen-Carson product lines—Dark & Lovely and Optimum—in complaints filed against the companies.
The fact that Optimum is named in litigation does not establish that every Optimum product is defective or that every user has a viable lawsuit.
What Is the Current Optimum Hair Relaxer Lawsuit Status?
The federal hair-relaxer MDL remains active, and new member cases naming L’Oréal and SoftSheen-Carson continued to be filed during 2026.
The litigation remains in coordinated pretrial proceedings involving issues such as causation, expert evidence, individual exposure histories, and potential trial cases.
No verdict or court finding has established that Optimum hair relaxers caused uterine cancer in all users, and L’Oréal continues to dispute liability and scientific causation.
Has There Been an Optimum Hair Relaxer Recall?
The litigation discussed here is principally a product-liability proceeding rather than a recall-based case.
The cited sources do not document a CPSC or FDA recall of Optimum hair relaxer based on the uterine-cancer allegations discussed in the federal MDL.
A lawsuit can proceed without a product recall if a plaintiff can establish the elements required under applicable product-liability law.
Who May Be Affected?
Potentially affected consumers include women who used Optimum or other chemical hair relaxers regularly over an extended period and were later diagnosed with uterine, endometrial, ovarian, or another condition being evaluated in the litigation.
Frequent or long-term use can be relevant, but exposure alone does not establish causation or lawsuit eligibility.
A claim must be evaluated using the consumer’s specific product history, diagnosis, timing, medical records, and other potential risk factors.
Do I Qualify?
- Did you use Optimum hair relaxer regularly for several years before your diagnosis?
- Were you diagnosed with uterine, endometrial, ovarian, or another cancer currently being evaluated in hair-relaxer litigation?
- Do your medical records, pathology reports, or oncology records document the diagnosis and treatment?
- Can you identify Optimum through receipts, photographs, packaging, salon records, purchase history, or witness testimony?
An individualized legal review can determine whether product identification, exposure history, diagnosis, causation evidence, damages, potential defendants, and applicable filing deadlines support a claim.
What Evidence Should I Preserve?
Preserve photographs of Optimum products, packaging, ingredient labels, receipts, online purchase histories, salon records, credit-card statements, and any remaining containers.
Medical evidence may include pathology reports, operative reports, oncology records, imaging, hospitalization records, treatment plans, hysterectomy records, and physician documentation.
Consumers should also prepare a written history describing approximately when product use began, how often it was applied, where treatments occurred, and when use stopped.
