Introduction
If you are searching for monday hair care reviews, you are probably trying to answer a simple question: does this affordable pink bottle haircare brand actually work, or is the popularity mostly about packaging and social media?
The answer is more nuanced. MONDAY Haircare offers several shampoo and conditioner ranges designed for different hair needs. Its current lineup includes Smooth, Moisture, Volume, Repair, and Gentle, with Smooth specifically marketed toward curly, wavy and frizzy hair. The company says its shampoos and conditioners are dermatologically tested, pH balanced, cruelty free, and made without SLS or parabens.
Independent reviews and consumer discussions are more mixed. Many users report softer, smoother hair, while others describe buildup, dryness, scalp irritation or increased shedding. Those reports are individual experiences and do not establish that MONDAY products cause hair loss.
Here is what you should know before buying.
Is Monday Haircare actually good?
MONDAY Haircare can be a good budget option, particularly when you choose the range that matches your hair type. However, no shampoo or conditioner works equally well for everyone.
The biggest strength is variety. Instead of offering one universal formula, MONDAY currently separates its products by hair concern:
| MONDAY range | Best suited to |
|---|---|
| Smooth | Curly, wavy and frizz prone hair |
| Moisture | Dry, coarse and coily hair |
| Volume | Thin, fine and oily hair |
| Repair | Dry or damaged hair |
| Gentle | Hair and scalps needing extra care |
The brand’s official range currently lists these categories and describes the products as SLS and paraben free.
That makes product selection more important than simply asking whether MONDAY is “good.”
What do Monday shampoo and conditioner contain?
The formulas contain a mixture of cleansing agents, conditioning ingredients, silicones, oils, proteins, fragrance and preservatives.
The exact ingredient list can vary by product and market, so check the bottle you are purchasing rather than relying on an older review.
For example, the current U.S. Smooth Shampoo ingredient list includes cocamidopropyl betaine, glycerin, hydrolyzed wheat protein, avocado oil, dimethiconol, ethylhexylglycerin, phenoxyethanol, sodium benzoate and fragrance, among other ingredients.
These ingredients have different purposes:
- Glycerin helps attract and retain moisture.
- Hydrolyzed wheat protein is used for conditioning and improving the feel of hair.
- Dimethiconol and other silicones can help create a smoother, softer surface.
- Cocamidopropyl betaine is a cleansing ingredient commonly used in shampoos.
- Phenoxyethanol and sodium benzoate function as preservatives.
- Fragrance contributes to the product’s scent.
Calling an ingredient “synthetic” does not automatically mean it is dangerous. Likewise, seeing a plant derived ingredient does not automatically make a product better. The concentration, formulation, intended use and individual sensitivity all matter.
Monday Smooth Shampoo and Conditioner review
Smooth is probably the most relevant MONDAY range if your main concerns are frizz, waves, curls and manageability.
MONDAY currently markets Smooth toward curly, wavy and frizzy hair. Its official product information highlights wheat protein, coconut oil and avocado oil, while the brand describes the formula as designed to smooth and reduce frizz.
The U.S. product page also highlights coconut oil, shea butter, vitamin E and panthenol among the ingredients associated with the Smooth range.
What can you expect?
A smoothing shampoo and conditioner can make hair feel softer and look shinier without permanently changing the underlying structure of the hair.
You may notice:
- Easier detangling
- Reduced appearance of frizz
- More surface smoothness
- Better shine
- Softer lengths
- Improved manageability
However, if your hair is very fine, heavily coated with styling products or prone to buildup, richer conditioning ingredients may not feel ideal.
Is Monday good for curly hair?
Yes, MONDAY Smooth is specifically marketed for curly, wavy and frizzy hair, but individual results can vary considerably.
The company describes Smooth as suitable for curly, wavy and frizz prone hair.
Consumer discussions also show both positive and negative experiences. Some curly hair users report that MONDAY makes their hair soft and smooth, while others report dryness, heaviness or changes in curl appearance.
This is an important distinction: a product being marketed for curly hair does not mean it will automatically suit every curl pattern or porosity.
If your curls become limp or coated, you may need to reduce the amount of conditioner or occasionally use a clarifying shampoo.
Does Monday shampoo cause hair loss?
There is not enough evidence to conclude that MONDAY shampoo causes hair loss.
This is one of the most important points in any Monday shampoo review because online discussions contain numerous reports of increased shedding.
Reddit discussions include people who say they experienced shedding, dryness, itching or buildup after using MONDAY products. Other users in the same discussions report excellent results and continued use without problems.
That means these reports should be treated as consumer experiences rather than proof of causation.
Hair shedding can have many causes, including genetics, hormonal changes, illness, nutritional issues, stress, postpartum changes, scalp conditions and other factors. If you experience sudden or significant hair loss after introducing any product, stop using it and consider speaking with a dermatologist or other qualified healthcare professional.
Monday shampoo ingredients: what stands out?
The ingredient profile is neither unusually simple nor automatically problematic.
The current Smooth Shampoo formula contains several familiar cosmetic ingredients, including cleansing agents, conditioning polymers, silicones, glycerin, plant oils and preservatives.
One useful way to evaluate the formula is by asking what you actually need.
For dry hair
Ingredients such as oils, glycerin and conditioning agents may help improve softness and manageability.
For frizzy hair
Conditioning ingredients and silicones can help reduce the rough feel and visual appearance of frizz.
For fine hair
A heavier conditioning routine may make some fine hair look flatter. MONDAY therefore offers a separate Volume range for thin, fine and oily hair.
For sensitive scalps
Fragrance can be a consideration. MONDAY’s Gentle range is specifically described as having a lower percentage of fragrance than its other lines.
What about fragrance and preservatives?
Preservatives and fragrance are not automatically harmful, but they can matter if you are sensitive to particular ingredients.
Phenoxyethanol, sodium benzoate and ethylhexylglycerin appear in MONDAY formulas.
The brand also uses fragrance, with Smooth described as having a subtle gardenia scent.
If you know that fragranced hair care irritates your scalp, look closely at the ingredient list before buying.
The same principle applies to preservatives. Their presence is not by itself evidence that a product is unsafe. Preservatives are commonly used to help prevent microbial growth in water based cosmetic products.
Monday hair care reviews from consumers
Consumer feedback is mixed rather than universally positive or negative.
Positive experiences commonly mention:
- Soft hair
- Smoother ends
- Pleasant fragrance
- Good lather
- Affordable pricing
- Attractive packaging
- Improved manageability
Negative experiences include reports of:
- Buildup
- Dryness
- Itchy scalp
- Hair feeling heavy
- Increased shedding
Recent Reddit discussions from 2026 demonstrate this split. Some users report loving MONDAY for curly, wavy or mixed textured hair, while others say the products made their hair feel dry or contributed to concerns about shedding.
The takeaway is not that one side is necessarily right. It is that haircare results are highly individual.
Monday shampoo vs other affordable brands
MONDAY competes in a crowded drugstore and affordable haircare market.
The brand’s appeal comes from combining relatively accessible pricing with attractive packaging, multiple formulas and ingredients associated with conditioning and smoothing.
Independent beauty publications have also recognized MONDAY as a budget friendly option. PEOPLE named MONDAY Volume Shampoo its best budget option in a tested roundup of shampoos for thinning hair, while other beauty coverage has highlighted MONDAY products among affordable shampoo choices.
That does not mean it is automatically better than every alternative.
When comparing products, consider:
- Your hair texture
- Scalp condition
- Whether your hair is colored
- How often you wash
- Whether you experience buildup
- Your fragrance preferences
- Whether you need moisture, volume, repair or smoothing
Is Monday shampoo color safe?
MONDAY’s formulas may be suitable for many color treated hair routines, but “color safe” should not be interpreted as a guarantee that your color will never fade.
The brand emphasizes sulfate free formulations and does not list SLS among its ingredients.
Still, colored hair can respond differently depending on the dye, treatment, porosity and washing routine. If preserving expensive salon color is your priority, compare the exact formula with your stylist’s recommendation.
What is the value of Monday Haircare?
Value is one of MONDAY’s strongest selling points.
The U.S. site currently lists the Smooth shampoo and conditioner at $7.99 on its product page, although prices can change and may differ by retailer or region.
That makes MONDAY particularly interesting for people who want an affordable shampoo and conditioner without moving entirely into basic low cost formulas.
The brand also says its bottles are recyclable and that its products are cruelty free.
Monday shampoo lawsuit: what happened?
Yes, there was a 2025 lawsuit involving MONDAY Haircare’s parent company, but it was about packaging, not allegations that the shampoo causes hair loss.
A California consumer, Silvia Garcia, filed a class action against Zuru LLC in July 2025 concerning the amount of empty space in a MONDAY shampoo bottle. The case involved allegations of deceptive “slack fill.” According to reporting on the case, the federal court dismissed the claims in December 2025, finding that the packaging disclosed the product’s volume and that the allegations did not meet the reasonable consumer standard.
This is important because online searches can incorrectly connect MONDAY Haircare with lawsuits concerning other haircare companies.
The packaging lawsuit should not be presented as evidence that MONDAY shampoo causes hair damage or hair loss.
Monday Haircare pros and cons
Pros
- Affordable compared with many salon products
- Multiple formulas for different hair types
- Smooth range targets frizz and textured hair
- No SLS or parabens according to the brand
- Dermatologically tested according to MONDAY
- Cruelty free
- Recyclable bottles
- Attractive, easy to recognize packaging
- Strong consumer and editorial interest
Cons
- Results vary between users
- Fragrance may not suit sensitive scalps
- Some users report buildup or dryness

- Rich conditioning ingredients may not suit every fine hair type
Final verdict: Are Monday hair care products worth buying?
For many shoppers, MONDAY is worth trying, particularly if you want affordable haircare and select the range that matches your hair type.
The strongest case for monday hair care reviews is its combination of price, variety and formulas designed around specific concerns. Smooth makes the most sense for frizz prone curly or wavy hair, Moisture for dry coarse hair, Volume for fine or oily hair, and Repair for damaged hair.
The main reason to be cautious is individual compatibility. Consumer reviews show that some people love the softness and smoothing effect while others report buildup, irritation or shedding. Those experiences should not be confused with clinical evidence that MONDAY causes hair loss.
Overall, I would rate MONDAY as a reasonable budget haircare brand worth considering, but not a universal winner. Your hair type, scalp sensitivity and the specific formula matter more than the brand name.
