MONDAY Haircare has become a widely recognized drugstore haircare brand, but online complaints about shedding, dryness, scalp irritation, and product build-up have pushed the Monday Shampoo Lawsuit into search results and social-media discussions. The legal picture, however, is different from many of the hair-loss claims circulating online.
A real proposed class action was filed against Zuru, LLC in 2025, but it concerned allegedly deceptive shampoo packaging—not allegations that the shampoo caused hair loss. The federal case was later dismissed in December 2025.
This article separates that documented court case from consumer hair complaints. It also examines settlement status, ingredients, reviews, Reddit discussions, ownership, potential future litigation, and what consumers can reasonably do if they believe a hair product has caused problems.
Why Are People Searching for the Monday Shampoo Lawsuit?
Search interest appears to come from two issues that are often blended together online: consumer complaints about hair problems and an actual lawsuit involving MONDAY Haircare products.
Some users have reported increased shedding, dry or brittle-feeling hair, scalp discomfort, and build-up after using certain products. Similar experiences appear in product reviews and Reddit discussions, although individual reviews cannot establish that a shampoo caused the reported condition.
Separately, plaintiff Silvia Garcia filed a proposed class action against Zuru, LLC in the U.S. District Court for the Central District of California on July 25, 2025. The case was Garcia v. Zuru, LLC, No. 5:25-cv-01908.
That litigation was about alleged “slack-fill”—essentially a claim that the size and opaque design of shampoo packaging could mislead consumers regarding how much product it contained. It was not a hair-loss injury lawsuit.
That distinction matters. Reports of shedding online should not be described as proven injuries caused by MONDAY products simply because a separate consumer class action existed.
Is There an Active Monday Shampoo Lawsuit?
There is a documented federal lawsuit involving MONDAY Haircare’s packaging, but the available federal court record shows that the case was terminated rather than remaining active.
Garcia v. Zuru, LLC was filed in California federal court in July 2025 as a proposed class action. The plaintiff challenged allegedly misleading packaging practices associated with MONDAY shampoo bottles.
On December 9, 2025, U.S. District Judge Mark C. Scarsi entered judgment dismissing the case. The plaintiff’s claims for injunctive relief were dismissed without prejudice for lack of standing, while her other claims were dismissed with prejudice. The judgment states that the plaintiff would “take nothing” from the action.
Therefore, as of the latest information reviewed in August 2026, that federal case should not be described as a pending class action.
Equally important, this lawsuit should not be presented as evidence that MONDAY shampoo has legally been found to cause hair loss. The dispute concerned packaging, while hair-loss concerns primarily appear in consumer reviews and online discussions.
Has Any Settlement Been Announced?
No settlement is reflected in the federal court disposition of Garcia v. Zuru, LLC. Instead, the court dismissed the action in December 2025.
That means consumers should be cautious about websites or social-media posts suggesting there is automatically a MONDAY shampoo settlement payment, compensation program, or class-action claim form connected with that case.
| Question | Current Status |
|---|---|
| Federal case filed? | Yes, in July 2025 |
| Hair-loss case? | No; the documented case concerned packaging |
| Case still active? | Court record shows it was dismissed |
| Settlement announced? | No settlement reflected in the disposition reviewed |
| Public claim form? | No verified claim process identified |
A settlement generally requires an agreement between the parties and, in class litigation, often involves court procedures governing class members, notices, claims, and payments. A dismissed case does not automatically create compensation rights.
Consumers should verify settlement information against actual court records before submitting personal information to any website claiming to process compensation.
What Hair Problems Have Consumers Reported?
Consumer reports do not all describe the same experience. MONDAY’s own website contains hundreds of reviews across individual product lines, including positive feedback, while some reviewers and social-media users describe unwanted hair or scalp changes.
The most frequently discussed concerns online include:
- Increased shedding or apparent hair loss
- Dry or brittle-feeling strands
- Itchy or uncomfortable scalp
- Product build-up
- Changes in hair texture or manageability
These experiences are relevant when evaluating consumer sentiment, but they remain anecdotal unless supported by appropriate medical, scientific, or legal evidence establishing causation.
Increased Hair Shedding
Hair shedding is the issue that generates some of the strongest online reactions. Certain Reddit users report noticing more hair in brushes, showers, or around the home after beginning a MONDAY routine. Other users in the same discussions report using the products without increased shedding.
MONDAY’s own SMOOTH product page also contains at least one customer review alleging significant shedding after using a conditioner. Again, a customer review records an individual’s experience; it does not demonstrate scientifically that the product caused the shedding.
Hair loss has numerous possible causes. Timing alone cannot establish that a recently introduced shampoo was responsible.
Dry Hair
Dryness is another complaint appearing in consumer discussions. A shampoo may feel effective for one person’s scalp and overly cleansing or drying for another because hair texture, porosity, chemical treatments, washing frequency, and the rest of a person’s routine differ substantially.
MONDAY also sells different formulations for different hair needs. For example, its MOISTURE line is marketed toward dry, coarse, and stressed hair, while VOLUME is aimed more toward fine or oily hair.
Consequently, a report that one formulation left someone’s hair dry cannot automatically be generalized to every MONDAY product or every consumer.
Scalp Irritation
Some online users describe itching or scalp discomfort while using the products. Such reports deserve attention, particularly when irritation appears soon after a new product is introduced.
Cosmetic formulas contain numerous ingredients, including cleansing agents, preservatives, fragrances, conditioning agents, and botanical ingredients. Individual sensitivity or allergy can occur even when an ingredient is permitted for cosmetic use.
MONDAY specifically advises consumers with a known allergy to an ingredient to avoid products containing it and recommends consulting a physician or healthcare professional when uncertain. The company also says consumers should check the bottle because formulations can differ by market and change over time.
Persistent redness, burning, sores, swelling, or significant itching should be evaluated rather than assumed to be normal adjustment to a shampoo.
Product Build-Up
Build-up is another issue discussed online, especially among people using conditioning products, silicones, styling products, oils, or dry shampoo.
Certain MONDAY formulas contain ingredients such as dimethicone or dimethiconol. For example, the current ingredient list for the MOISTURE shampoo includes both compounds.
Whether someone experiences noticeable build-up depends on much more than a single ingredient. Hair type, washing frequency, water quality, styling products, cleansing technique, and the combination of products used can all affect how hair and scalp feel.
Reddit discussions occasionally attribute problems to silicone accumulation, but those explanations are user opinions rather than clinical findings.
Does Monday Shampoo Actually Cause Hair Loss?
Current evidence reviewed for this article does not establish that MONDAY shampoo causes hair loss generally.
Online reports create a signal worth discussing, but consumer anecdotes cannot by themselves prove medical causation. A person may begin shedding after changing shampoo while another factor—stress, nutritional deficiency, hormonal changes, illness, genetics, medication, scalp disease, or hair damage—is responsible.
A 2026 UK pharmacy review similarly noted that no UK regulatory authority it identified had established a confirmed connection between MONDAY shampoo and clinically significant hair loss.
There is also an important legal distinction. The documented Garcia lawsuit did not seek to prove that MONDAY shampoo caused hair loss. It concerned allegations regarding the amount of product and bottle presentation.
Therefore, statements such as “MONDAY shampoo was sued for causing hair loss” would mischaracterize the documented federal litigation.
Individual adverse reactions remain possible with cosmetic products. Someone experiencing sudden or persistent shedding should stop focusing solely on online anecdotes and consider obtaining a professional assessment of the underlying cause.
What Ingredients Are in Monday Shampoo?
There is no single ingredient list that applies to every MONDAY shampoo. The formula depends on the product line and may also change by market or over time. MONDAY itself advises checking the packaging for the most accurate ingredient information.
For example, the current MOISTURE shampoo listing includes ingredients such as water, cocamidopropyl betaine, disodium laureth sulfosuccinate, sodium cocoyl isethionate, dimethicone, glycerin, sodium hyaluronate, shea butter, preservatives, fragrance, and other formulation ingredients.
The VOLUME formula differs and lists ingredients including sodium C14-16 olefin sulfonate, hydrolyzed collagen, macadamia seed oil, sodium methyl cocoyl taurate, salicylic acid, fragrance, and menthol.
MONDAY also highlights ingredients used across portions of its range, including:
- Shea butter
- Coconut oil
- Vitamin E
- Panthenol
- Keratin
- Amino acids
- Hydrolyzed proteins
- Plant extracts
The company states that its range is formulated without SLS and parabens.
Because formulas differ, ingredient-related claims should always identify the specific product rather than treating every pink MONDAY bottle as identical.
Are Any Ingredients Considered Dangerous?
The presence of a chemical-sounding ingredient name does not by itself mean a shampoo is dangerous. Cosmetic formulations use surfactants, preservatives, fragrances, conditioning agents, silicones, proteins, and other substances for specific functions.
MONDAY describes its current shampoo and conditioner formulas as dermatologically tested and says its range contains no sulfates or parabens.
However, “safe for general cosmetic use” and “suitable for every individual” are not identical concepts. A person can be sensitive or allergic to an ingredient that many other consumers tolerate without difficulty.
Fragrance components, cleansing agents, preservatives, and botanical ingredients may cause irritation in susceptible individuals. The relevant question is therefore not simply whether an ingredient appears on an alarming internet list, but its concentration, formulation, exposure, individual sensitivity, and the evidence concerning the specific product.
Consumers who know they have allergies should compare the bottle’s ingredient list with their known triggers. MONDAY itself recommends avoiding products containing known allergens and consulting a healthcare professional when uncertain.
Is Monday Shampoo Bad for Your Hair?
It would be too broad to characterize MONDAY shampoo as universally “bad” for hair.
Haircare products interact differently with different hair and scalp types. Someone with oily, fine hair may respond differently to a formula than someone with bleached, curly, coarse, damaged, or highly sensitive hair.
The brand sells separate formulas for different needs, including SMOOTH, REPAIR, MOISTURE, and VOLUME. Its current website describes the range as dermatologically tested and pH-balanced.
At the same time, negative experiences should not simply be dismissed. Consumers have reported dryness, build-up, irritation, breakage, and increased shedding in reviews and online forums.
The balanced conclusion is that product suitability is individual. If someone’s scalp becomes persistently irritated or shedding noticeably increases after introducing a product, discontinuing it and assessing other possible causes is more sensible than continuing solely because the product works well for other reviewers.
What Do Dermatologists Say About Hair Loss and Shampoo?
Hair shedding is a symptom rather than a diagnosis, and determining its cause usually requires more information than the shampoo someone happens to be using.
Possible explanations can include genetic pattern hair loss, telogen effluvium following stress or illness, nutritional deficiencies, hormonal changes, scalp disorders, medication effects, traction, heat or chemical damage, and breakage that may be mistaken for shedding from the root.
A shampoo can also irritate an individual’s scalp or leave hair feeling dry, potentially contributing to breakage in some circumstances. That still does not establish that a particular commercial shampoo causes follicular hair loss across consumers.
The timing matters, but so do other changes occurring during the same period.
People experiencing rapid shedding, visible thinning, bald patches, scalp inflammation, pain, or symptoms that continue after discontinuing a product should consider evaluation by a dermatologist or another qualified healthcare professional. Photographs taken over time and a record of recent products, medications, illnesses, diet changes, and stressors can help provide useful context.
What Are Consumers Saying in Reviews?
Reviews of MONDAY products are mixed rather than uniformly negative.
The brand’s current product pages display hundreds of reviews. The SMOOTH product, for example, had a reported 4.4 rating based on hundreds of reviews when reviewed, while its page also contained a customer complaint alleging substantial hair shedding.
That combination illustrates why review evidence needs context. A product can have many satisfied customers while some users report serious problems.
Positive reviews may describe softness, manageability, scent, hydration, or cleaner-feeling hair. Negative discussions commonly focus on:
- Shedding
- Dryness
- Build-up
- Scalp itching
- Breakage
- Changes in texture
Neither positive nor negative reviews substitute for controlled evidence.
From a legal perspective, a large number of similar complaints can sometimes encourage attorneys or regulators to investigate an issue. But complaints alone do not prove product defect, negligence, causation, or damages.
Monday Shampoo Reviews About Hair Loss
Hair-loss reviews receive disproportionate attention because shedding is understandably alarming.
Some consumers on Reddit say they noticed increased hair in brushes and showers after using MONDAY products. One discussion contains reports of dryness, build-up, itching, and shedding, alongside other users who say they like the products and have not experienced increased hair loss.
This conflicting feedback is significant.
If a product caused the same reaction predictably across users, evidence would generally be easier to identify. Instead, the available online reports show varied experiences involving different formulas, hair types, routines, health backgrounds, and lengths of use.
A review can help identify a potential pattern worth investigating. It cannot determine medical causation for another consumer.
How Has Reddit Influenced the Conversation?
Reddit has played a substantial role in keeping MONDAY hair-loss concerns visible.
Users frequently search Reddit before purchasing beauty products because discussions can contain longer personal accounts than retailer reviews. Threads concerning MONDAY include claims involving shedding, dryness, itchy scalps, build-up, and hair breakage.
The discussions are not uniformly negative. Some users say the products work well for their hair, and others acknowledge that stress, anemia, pre-existing hair-loss conditions, or other factors could have contributed to their shedding.
That uncertainty is exactly why Reddit should be treated as anecdotal evidence.
Social platforms can identify emerging consumer concerns quickly, but they lack the controls necessary to determine causation. Users generally have different hair types, medical histories, routines, water conditions, styling practices, and product combinations.
Reddit therefore explains much of the public conversation, but it does not establish the legal or scientific conclusion.
Who Owns MONDAY Haircare?
MONDAY Haircare was conceptualized and founded by New Zealand entrepreneur Jaimee Lupton. The brand says it was founded in 2020 with the goal of offering salon-style haircare at a more accessible price point.
The corporate structure matters in the lawsuit context because the documented federal litigation named Zuru, LLC as the defendant rather than Jaimee Lupton individually. Federal docket records identify Zuru LLC as the defendant in Garcia v. Zuru, LLC.
ZURU Edge is associated with MONDAY’s broader ownership and business operations. Reporting on the ownership structure describes MONDAY as part of ZURU Edge, within the wider ZURU business group.
Legal articles should identify the actual defendant named in a court filing rather than casually treating founders, parent companies, subsidiaries, and brands as interchangeable.
How Do Hair Loss Claims Compare With Other Shampoo Controversies?
Haircare controversies often develop in a similar pattern. Consumers notice shedding or breakage, individual stories spread through reviews and social media, ingredient discussions follow, and searches for terms such as “lawsuit,” “recall,” or “class action” begin increasing.
That progression does not necessarily mean litigation exists.
Hair-loss allegations can also involve different legal theories depending on the evidence. A potential product case might concern defective formulation, inadequate warnings, misleading advertising, breach of warranty, or another consumer-protection theory.
The MONDAY situation requires particular care because there was a real lawsuit involving shampoo, but the documented Garcia case dealt with alleged packaging deception rather than hair-loss injuries.
Mixing those two subjects can create a misleading narrative: consumers report hair loss, a lawsuit existed, therefore the lawsuit must have alleged hair loss. The court record does not support that conclusion.
Any future hair-injury case would need to be evaluated on its own allegations, evidence, procedural status, and applicable law.
What Should Consumers Do If They Experience Hair Problems?
Consumers who experience unusual shedding, scalp irritation, breakage, or another significant change after starting a hair product should focus first on documenting and addressing the problem rather than assuming a legal cause.
Reasonable steps can include:
- Stop using a product if it appears to trigger significant irritation or other unwanted effects.
- Keep the bottle, packaging, lot or batch information, and purchase receipt.
- Photograph visible scalp or hair changes over time.
- Record when the product was started and when symptoms appeared.
- Note other medications, illnesses, stressful events, treatments, or hair products introduced around the same period.
- Contact the manufacturer or retailer when appropriate.
- Seek medical evaluation for persistent, severe, or unexplained symptoms.
MONDAY advises consumers with known ingredient allergies to avoid the relevant products and consult a healthcare professional if they are uncertain about an ingredient.
Documentation also becomes important if a consumer later reports an adverse event, submits a complaint, or consults an attorney. Legal causation generally requires more than remembering that hair problems began sometime after a product purchase.
Could Future Lawsuits Still Be Filed?
Yes. The dismissal of one lawsuit does not prevent every possible future lawsuit involving a company or product.
Garcia v. Zuru, LLC addressed particular claims brought by a particular plaintiff concerning MONDAY packaging. Most of the plaintiff’s claims in that action were dismissed with prejudice, while the injunctive-relief claims were dismissed without prejudice for lack of standing.
That judgment should not be interpreted as a universal court ruling resolving every conceivable complaint involving MONDAY products.
A different consumer could theoretically pursue different legal claims if sufficient facts and evidence existed. Whether such a case could proceed would depend on matters including jurisdiction, applicable statutes, injury, causation, product evidence, limitations periods, and the specific causes of action asserted.
Likewise, future regulatory action or another class action cannot be predicted simply from online complaints.
Until an actual complaint is filed, however, a possible future hair-loss lawsuit remains hypothetical. It should not be reported as an existing case.
Latest Status of the Monday Shampoo Lawsuit
As of August 2026, the clearest documented legal development is the disposition of Garcia v. Zuru, LLC.
The proposed federal class action was filed on July 25, 2025, in the Central District of California. Court records identify the matter as Case No. 5:25-cv-01908.
Judge Mark C. Scarsi entered judgment on December 9, 2025. The court dismissed the plaintiff’s injunctive-relief claims without prejudice for lack of standing and dismissed the remaining claims with prejudice. The case was terminated.
The essential distinction is:
A real lawsuit existed, but it concerned allegedly misleading packaging—not allegations that MONDAY shampoo caused hair loss.
Consumer reports concerning shedding, dryness, scalp irritation, and build-up continue to circulate online. Those reports may be important to individual users, but they do not establish a judicial finding that MONDAY products cause hair loss.
No settlement or compensation program arising from the dismissed Garcia case is reflected in the court disposition reviewed for this article.

FAQs
Is there a Monday Shampoo Lawsuit about hair loss?
The documented federal MONDAY case concerned allegedly deceptive shampoo packaging, not hair-loss injuries. Consumer reports about shedding exist online, but they should not be confused with the claims litigated in Garcia v. Zuru, LLC.
Was the MONDAY Haircare class action dismissed?
Yes. The federal court entered judgment on December 9, 2025. Most claims were dismissed with prejudice, while claims seeking injunctive relief were dismissed without prejudice for lack of standing.
Has a MONDAY shampoo settlement been reached?
No settlement is reflected in the disposition of the Garcia litigation reviewed here. The case ended through dismissal, so consumers should verify online compensation claims against official court information.
Does MONDAY shampoo cause hair loss?
A causal relationship has not been established by the evidence reviewed here. Some consumers report shedding, but hair loss has many possible causes, and individual reviews cannot establish that a shampoo caused it.
What complaints have consumers made about MONDAY shampoo?
Online consumers have described increased shedding, dryness, scalp itching, build-up, and breakage. Experiences vary substantially, and other users report positive results without increased hair loss.
Can consumers file a claim for compensation?
There is no verified settlement claim process associated with the dismissed Garcia case identified here. A consumer with an alleged injury would need to evaluate their individual circumstances and any available legal options separately.
Final Thoughts
The Monday Shampoo Lawsuit requires an important distinction between documented litigation and online hair-loss allegations. A proposed class action was filed against Zuru, LLC in 2025, but the case challenged MONDAY shampoo packaging rather than alleging that the products caused consumers’ hair to fall out. The federal court dismissed that action in December 2025.
Meanwhile, consumers continue to report experiences involving shedding, dryness, irritation, and build-up. Those reports can help identify concerns worth examining, but they do not prove that MONDAY shampoo causes hair loss.
Consumers experiencing significant problems should preserve relevant evidence and consider medical evaluation rather than relying solely on social-media explanations. Any future lawsuit would have to establish its own legal claims through evidence, causation, applicable law, and court proceedings.
