Is the Monday Shampoo Lawsuit Real or a Scam?
The Monday shampoo lawsuit is real, but it’s not what most people think it is. A federal class action was filed against Zuru, LLC, the company behind MONDAY Haircare, in the Central District of California. The case number is 5:25-cv-01908-MCS-AJR .
The lawsuit is called Garcia v. Zuru, LLC. It’s a slack-fill case, not a hair loss case. The plaintiff alleges that MONDAY Haircare bottles are filled to only about 75 percent capacity, leaving significant empty space that misleads consumers about how much product they’re getting .
On December 9, 2025, the court issued a ruling on Zuru’s motion to dismiss. The judge found that the allegations were implausible and dismissed the complaint, though the plaintiff may have the option to amend .
This is critical to understand. The case exists. It’s real. But it’s about bottle fill levels, not hair damage. And it’s currently facing a significant legal hurdle after the December 2025 ruling.
Key Takeaway: The Garcia v. Zuru case is a slack-fill lawsuit, not a hair loss case. Anyone telling you there’s a Monday shampoo hair loss settlement is lying or confused.
How Much Could You Get from the Monday Shampoo Lawsuit?
There is no payout amount, and anyone who gives you a number is guessing. The case has not settled. No class has been certified. No damages have been calculated .
Here’s what the current status means for money:
| Stage | What It Means | Money Available? |
|---|---|---|
| Filed | Lawsuit submitted to court | No |
| Motion to Dismiss | Defendant challenges the claims | No |
| Ruling | Court dismisses or allows case to proceed | No |
| Class Certification | Judge approves group status | No |
| Settlement Talks | Parties negotiate a number | Not yet |
| Claims Period | Class members file forms | Not yet |
| Distribution | Checks mailed | Not yet |
The case is currently in a precarious position. The December 2025 ruling dismissed the complaint. Unless the plaintiff successfully amends and survives a second motion to dismiss, this case may not produce any money at all .
Key Takeaway: The Monday shampoo lawsuit payout is not yet determined because there is no settlement, no certified class, and the case is currently facing dismissal.
Reality Check: No one will text you about a Monday shampoo settlement. No legitimate claims administrator asks you to pay a fee to receive money. If you get a message saying you qualify for a Monday shampoo payout, delete it. That’s a scam capitalizing on real confusion about this case.
Who May Qualify for the Monday Shampoo Lawsuit?
You may qualify if you purchased MONDAY Haircare shampoo in a bottle that allegedly contained illegal slack-fill. The proposed class would cover consumers who bought the product in the United States .
The lawsuit focuses on opaque bottles where consumers cannot see the actual fill level before purchase. The plaintiff alleges that disclosures of net volume do not give reasonable consumers a meaningful understanding of how full the bottle actually is .
If the case survives dismissal and reaches settlement, class members would likely be identified through purchase records, receipts, or self-identification through a claims process. But none of that exists yet.
The hair loss complaints you’ve seen on social media and review sites are not part of this lawsuit. If you experienced hair damage, you are not covered by the Garcia v. Zuru slack-fill case. You would need a different legal theory and a different lawsuit entirely .
Key Takeaway: The current lawsuit covers bottle fill levels, not hair damage. If you used MONDAY and lost hair, this case does not represent you.
What Does the Monday Shampoo Lawsuit Actually Allege?
The lawsuit alleges that MONDAY Haircare bottles contain illegal nonfunctional slack-fill that misleads consumers about the quantity of shampoo they’re purchasing. The complaint claims the bottles are filled to only about 75 percent capacity, with the rest being empty space .
Slack-fill is the difference between a container’s actual capacity and the volume of product inside. Nonfunctional slack-fill is empty space that serves no legitimate purpose. The lawsuit argues that MONDAY’s opaque packaging prevents consumers from seeing how much product they’re actually getting .
The plaintiff argues that reasonable consumers expect a bottle to be filled roughly to capacity, and that net volume disclosures do not fix the problem because consumers cannot mentally convert fluid ounces to visual fill levels .
However, the court disagreed in its December 2025 ruling. The judge found that because MONDAY bottles disclose fluid volume on the label, and because liquid products are sold by volume in California, a reasonable consumer would understand they’re getting 12 fluid ounces even if the bottle could theoretically hold more .
The court also noted that the bottle’s pump mechanism and dip tube occupy space, which is normal for mass-produced liquid products .
What Are the Hair Loss Complaints About Monday Shampoo?
Hair loss complaints about MONDAY Haircare are widespread on social media and product review sites, but no court has verified them. Users have reported hair breaking, snapping, falling out in chunks, and scalp irritation after using the product .
A TikTok video from user Desiree Gonzalez in 2024 went viral after she claimed her hair started falling out after three weeks of using MONDAY shampoo and conditioner. The video drew over 4.3 million views and sparked thousands of similar complaints .
Product review sites contain dozens of similar reports. One reviewer wrote that their “hair’s been falling out in chunks after using this product for multiple months.” Another described “hair loss and scalp blistering” with “little red dots” on the scalp .
MONDAY’s response has been that only a tiny fraction of products generated complaints. The company stated that only 0.02 percent of the 1.8 million bottles they sold had reported issues, which they claimed was below the industry average .
Experts quoted in coverage of the complaints suggested that silicones in the shampoo, while generally safe, might react poorly with bleached hair or that mineral buildup could contribute to breakage. These are theories, not verified findings .
Key Takeaway: Hair loss complaints are real and numerous, but they are unverified allegations. No court has determined that MONDAY products cause hair damage.
Can You Join a Monday Shampoo Hair Loss Lawsuit?
You cannot join a Monday shampoo hair loss lawsuit right now because no such class action has been certified. The active lawsuit is about slack-fill, not hair damage .
If you want to pursue a claim for hair damage, you have options, but they are different from joining a class action:
- Consult a product liability attorney. Many law firms handle individual hair damage cases. You may be able to pursue a claim outside of any class action.
- Document your experience. Save the product bottles, take dated photos of your hair before, during, and after use, and keep receipts.
- See a dermatologist. Medical records linking your hair loss to product use strengthen any potential claim.
- Report to the FDA. You can file an adverse event report through the FDA’s cosmetics reporting system.
- Monitor class action news. If a hair loss class action is filed in the future, you may have the option to join then.
The key difference is that class actions represent groups automatically unless you opt out. Individual lawsuits give you control but require more effort and expense.
Key Takeaway: No hair loss class action exists for MONDAY Haircare. If you were injured, you would need to pursue an individual claim with an attorney.
What Happens Next in the Monday Shampoo Lawsuit?
The Garcia v. Zuru slack-fill case is at a critical juncture after the December 2025 dismissal ruling. The plaintiff may file an amended complaint or appeal the decision.
Expected timeline:
- Late 2026: Plaintiff files amended complaint or case is dismissed with prejudice
- If amended: Second motion to dismiss or answer from Zuru
- If survives: Discovery and potential class certification proceedings
- 2027-2028: Possible settlement talks or trial
- If settlement: Claims period opens, typically 60 to 90 days
- If approved: Payments distributed 30 to 90 days after final approval
No specific dates have been set by the court for these stages. The case’s future depends heavily on whether the plaintiff can fix the pleading deficiencies identified in the December 2025 ruling .
