What the Lawsuit Alleges
The lawsuit alleges that Mielle’s Rosemary Mint products contain ingredients that cause hair loss, and that the companies never warned buyers. The consolidated complaint names three products: the Rosemary Mint Scalp & Strengthening Hair Oil, the Rosemary Mint Strengthening Shampoo and the Rosemary Mint Strengthening Conditioner. The plaintiffs say they lost hair and that buyers “have suffered scalp issues, blistering, and/or sores.”
The legal theory is consumer fraud, not a proven product defect: the complaint argues people would not have bought the products, or would have paid less, had the risk been on the label. It pleads fraud, unjust enrichment and state consumer-fraud laws and asks for refunds plus statutory and punitive damages. The earlier Gomes complaint also alleged the oil contained “dangerous levels of benzene” — an allegation, not a test result any court has accepted. Procter & Gamble bought Mielle in 2023. Both companies deny the claims.
Case Details
The main case is Williams v. Mielle Organics LLC, No. 1:24-cv-12763, in the U.S. District Court for the Northern District of Illinois, before Judge Steven C. Seeger. Three plaintiffs filed it on December 12, 2024 against Mielle Organics LLC and The Procter & Gamble Company (complaint). It replaced an earlier one-plaintiff suit, Gomes v. Mielle Organics LLC, No. 1:24-cv-12019, filed November 21, 2024 in the same court (complaint).
A separate case, Allen v. Mielle Organics LLC, No. 8:25-cv-00342 in federal court in California, challenged “Made in USA” and “natural” labels, not hair loss. According to case-tracking sites, it was voluntarily dismissed and closed on June 19, 2025.
Status: Dismissed Once, No Settlement
We could not confirm from the court record whether an amended complaint was filed or what has happened since. Some websites still describe the case as being in discovery, but they do not mention the 2025 dismissal. Treat any claim that the case is “settling” with suspicion. No recall has been announced for the Rosemary Mint products.

Who Would Be in the Class
The complaint proposes a class of all persons in the United States who bought the Products for personal or household use within the limitations period, plus state subclasses. That includes buyers who never lost hair, because the main claim is about overpaying. No court has certified that class.
There is nothing to join. You don’t sign up for a proposed class action. If a class is ever certified or a settlement is approved, a court-appointed administrator publishes an official notice. If the oil damaged your scalp or hair, keep the bottle, receipts or order emails, dated photos and any dermatologist records. A personal-injury claim is separate from this consumer case and has its own deadlines under state law, so talk to a lawyer instead of waiting for a class payout.
What Buyers Can Expect
For context, not as a prediction: when consumer-labeling class actions like this one settle, buyers usually get a modest per-product refund, often capped and sometimes higher with a receipt. A cash payout for hair loss itself would generally take an individual injury claim, not a class settlement. If a fund is created, you can estimate your share with our payout calculator.
How cases like this one end
Our copy of the federal courts’ own case database covers 24,037 other fraud casesclosed in U.S. federal district courts between 2015 and 2025, 27.4% of them filed as class actions:
- 17.3% ended in a settlement recorded by the court. Another 22.5% were dismissed voluntarily, which often follows a private settlement — so the real settlement share sits between 17.3% and 39.8%.
- 10.4% were decided on a motion before any trial.
- 1 in 111 reached a trial (0.9%), after a median of 30 months.
- Median time from filing to the end of the case: 7 months.
- Only 735 of them (3.1%) record a money award at all; the median of those is $663,000.

Three Things to Watch For
A viral product, a big search volume and no official claim process attract fake “settlement” pages:
“Mielle settlement: file before the deadline” sites
No Mielle settlement exists, so there is no deadline and no claims website. A page asking for your card number, bank details or a “processing fee” is not a court administrator.
Made-up payout tables
Articles listing amounts like $100 to $2,500 per person are not based on any court filing. They are often used to get you to submit your contact details to lead-generation forms that sell them to law firms.
“Send us your bottle for testing”
Keep your product, receipts and photos yourself. A real lawyer handling your claim will explain how evidence is preserved and won’t ask you to mail it to an anonymous address or pay for a lab test before you sign anything.
Mielle Rosemary Oil Lawsuit — Questions People Ask
Is the Mielle rosemary oil lawsuit real?
Yes. Williams v. Mielle Organics LLC, No. 1:24-cv-12763, was filed in the U.S. District Court for the Northern District of Illinois on December 12, 2024, against Mielle Organics and Procter & Gamble. It is a proposed class action, and its claims are allegations, not findings.
Is there a Mielle settlement or claim form?
No. As of October 2026 there is no settlement, no fund, no administrator and no claim form. The judge dismissed the original complaint on September 25, 2025, with permission to refile. If a settlement is ever approved, an official notice will name the administrator and the deadline.
Does Mielle rosemary oil cause hair loss?
That is what the lawsuit alleges. No court has found that it does, and Mielle and P&G deny it. No recall has been announced. If you had shedding, blisters or sores after using it, stop using it and see a dermatologist. The medical record matters more than any website.
Does the oil contain benzene?
The first complaint (Gomes) alleged “dangerous levels of benzene.” That is a claim in a lawsuit, not a published test result accepted by a court or regulator. The later three-plaintiff complaint focuses on a failure to warn about hair loss.
Which products are covered?
The complaint names the Mielle Organics Rosemary Mint Scalp & Strengthening Hair Oil, Rosemary Mint Strengthening Shampoo and Rosemary Mint Strengthening Conditioner, bought in the U.S. for personal or household use.
Why was the case dismissed?
Fraud claims in federal court have to state exactly which statements were misleading. On September 25, 2025, the judge ruled that the complaint said buyers were deceived without pointing to specific misrepresentations. The dismissal was without prejudice, which means the plaintiffs were allowed to try again.
Do I need to do anything now?
There is nothing to file for this case. If you were injured, keep the product, receipts and dated photos, and speak with a lawyer about an individual claim. State filing deadlines run on their own and won’t wait for a class action. Our guide to finding a personal injury lawyer explains what to ask.
Where can I see settlements that are actually paying?
Our list of open class action settlements shows cases with an approved settlement, an official claim website and a deadline. Mielle is not one of them.
Separate from this case: were you injured in the last 2 years?
Class-action payouts are fixed amounts through an administrator. A personal injury claim is a different case — and often worth far more. Free estimate, no obligation.
