Monday Shampoo Review 2026: Worth It?

Monday Haircare went viral on TikTok, then landed in almost every drugstore aisle. The pink bottles look expensive. The price tag says otherwise. That gap makes shoppers curious and a little suspicious.

I bought the Moisture and Volume bottles with my own money and washed with them for four weeks straight. I tracked shine, greasiness, tangles, and scalp comfort after every wash. I also read hundreds of buyer complaints, because a fair review needs the bad days too.

This post covers the smell, the lather, the ingredient list, the real results, and the things Monday handles poorly. No hype, no fluff, just what happened in my shower.

In A Nutshell:

• Monday shampoo costs very little and still feels premium. The bottles look like salon products. The pump free flip cap works fine. The price sits far below most brands with similar packaging.
• The formula skips SLS and parabens but still uses gentle cleansing agents. Cocamidopropyl betaine and sodium cocoyl isethionate do the washing. Some strict curly girl followers still flag one ingredient as a mild sulfosuccinate.
• Moisture works best on dry, straight to wavy hair. Hyaluronic acid, shea butter, and coconut oil add slip and shine. Thick coily hair may need a heavier mask afterward.
• Volume suits fine and oily hair. Hydrolyzed collagen and macadamia oil lift roots without heavy residue. It can feel drying on long, colored lengths.
• Silicones appear in the formula. Dimethicone creates instant smoothness. Buildup can show up after three or four weeks without a clarifying wash.
• A small group of users report itching, dryness, or breakage. Reactions stay rare, but they exist. Patch test if your scalp reacts easily.

Monday Haircare is a New Zealand born brand that launched in 2020. The founders wanted salon style bottles at supermarket prices. That idea worked. The brand now sells in the United States, the United Kingdom, Australia, and across Asia.

The range covers Moisture, Volume, Smooth, Repair, Clarify, Gentle, and Curl formulas. Each bottle targets one clear hair concern. The naming system removes guesswork at the shelf.

Every formula is vegan, cruelty free, and Leaping Bunny approved. The bottles carry dermatological testing claims and pH balanced labeling. The plastic is recyclable, and jumbo sizes cut packaging waste per ounce.

Celebrity fans pushed the brand further. Gracie Abrams and Addison Rae posted about it. TikTok videos tagged with the brand passed 25 million likes.

Popularity does not equal performance, though. Plenty of viral products disappoint once the camera turns off. That is exactly why I tested two full bottles instead of one wash.

Monday Moisture Shampoo Review

Moisture is the flagship. It targets dry, dull, coarse, and frizz prone hair. The hero ingredients are hyaluronic acid, shea butter, coconut oil, and vitamin E.

The first wash surprised me. My hair felt soft while still wet, which usually only happens after conditioner. The shampoo rinsed clean without that squeaky, stripped feeling.

Air dried results looked glossy. Frizz dropped noticeably around my hairline. Detangling took half the time it normally does.

The formula also works on color treated hair. My highlights showed no fading over four weeks of washing three times per week.

One issue appeared by week three. My roots started looking flat and slightly greasy by day two. The moisturizing agents build up on fine hair near the scalp.

A clarifying wash fixed it instantly. So Moisture earns a strong recommendation for medium to thick dry hair, with a monthly clarify session added to the routine.

Monday Volume Shampoo Review

Volume takes the opposite approach. It targets thin, fine, flat, and oily hair. The formula leans on hydrolyzed collagen, macadamia oil, and ginger extract.

The texture feels thinner in the palm than Moisture. It also lathers faster and needs less product per wash. One coin sized amount covers shoulder length hair.

Results showed up at the roots. My hair lifted away from the scalp and held that shape into the next day. Blow drying added even more body without mousse.

Oil control improved too. Day two hair stayed wearable instead of stringy.

The tradeoff hits the ends. My lengths felt slightly rough after three washes in a row. Fine hair users with long lengths will want conditioner only on the bottom half.

Volume also does very little for frizz. Humid weather still puffed my hair. Buy this one for lift, not for smoothness.

Unboxing Experience And First Impressions

The Amazon box arrived with both bottles wrapped in a single plastic sleeve. No fancy insert, no tissue paper, no branded card. Budget brands skip theater, and that is honestly fine.

The bottles themselves carry the experience. The pale pink plastic has a soft matte finish that feels nicer than the price suggests. The typography stays minimal and clean.

The flip cap opens with one thumb. It clicks shut firmly and survived four weeks of shower drops without cracking.

Weight distribution feels good. The 12 ounce bottle stands steady on a wet shelf. The 27 ounce jumbo version tips more easily on narrow ledges.

The first squeeze released a pearly white cream with a faint sheen. The scent hit immediately, floral and clean.

One small annoyance appeared. The cap opening is wide, so new users often dispense twice as much as needed. Squeeze gently for the first few washes.

Ingredients Breakdown

The Moisture ingredient list starts with aqua, cocamidopropyl betaine, disodium laureth sulfosuccinate, sodium cocoyl isethionate, glycol distearate, and dimethicone.

Cocamidopropyl betaine is a coconut derived cleanser. It creates lather while staying mild on the scalp barrier.

Sodium cocoyl isethionate does the heavy lifting. Dermatologists rate it as gentle, and it works well in sensitive scalp and color safe formulas.

Glycol distearate creates that pearly look. It adds no cleaning power at all.

Dimethicone is the silicone that delivers instant smoothness. It coats the strand and reflects light. Silicones are safe, but they need occasional clarifying to avoid buildup.

Hyaluronic acid binds water to the hair surface. Shea butter seals the cuticle. Coconut oil adds shine, and vitamin E offers antioxidant support.

Fragrance sits in the list too. That matters for anyone with fragrance sensitivity, since it is the most common trigger in shampoo reactions.

Is Monday Shampoo Really Sulfate Free?

The label says no sulfates. That claim refers to SLS and SLES, the two harsh detergents most people avoid.

Neither appears in the formula. So the claim holds up under standard industry definitions.

Strict ingredient watchers raise one point. Disodium laureth sulfosuccinate contains the word sulfo and comes from a similar chemical family.

The difference matters, though. Sulfosuccinates are far milder than sulfates. They clean gently and rarely strip color or natural oils.

Curly girl method purists still exclude them in some versions of the rules. Most cosmetic chemists consider them perfectly acceptable for curls.

The bigger curly girl conflict is dimethicone. Water soluble silicones are allowed under modern rules, but dimethicone is not water soluble.

So the honest answer splits in two. Monday is sulfate free by normal standards, but it is not fully curly girl compliant because of the silicone content.

Scent, Lather And Wash Day Feel

The scent is the part people remember. Moisture smells like soft florals with a creamy vanilla base. Volume smells lighter and slightly citrus fresh.

Both fragrances stay medium strength in the shower. They fade to a faint whisper once hair dries. The scent does not linger for three days like some drugstore brands promise.

Lather builds fast for a sulfate free formula. Two pumps produced a dense foam on wet hair. That surprised me, since gentle surfactants usually foam weakly.

The wash feel is smooth rather than slippery. The product spreads easily from roots to mid lengths.

Rinsing takes about twenty seconds. No film, no residue, no heaviness.

One negative stands out. A single wash does not cut through heavy styling product or dry shampoo buildup. Double cleansing solves it, which uses more product than expected over a month.

Results After Four Weeks

Week one delivered the honeymoon phase. Hair felt soft, shiny, and easy to comb. The visual difference showed in photos.

Week two held steady. Frizz stayed controlled, and my scalp felt calm with zero itching.

Week three brought the buildup. Roots looked flatter and greasier faster. This is the silicone effect that most reviews skip over.

I used a clarifying shampoo once, and the reset worked completely. Week four returned to week one quality.

Breakage stayed unchanged. Monday does not repair damage the way bond builders do. It smooths the surface rather than rebuilding the inner structure.

Shedding stayed normal for me. Some online reviewers report increased shedding and dryness, and a few describe serious reactions.

Those reports remain a small minority against millions of bottles sold. Still, they are real and worth respecting. Patch test if you have a reactive scalp or a history of fragrance allergies.

What Monday Shampoo Does Not Do Well

Honest reviews name the weak spots. Monday has several.

It does not repair damaged bonds. Bleached or chemically straightened hair needs a treatment product alongside it.

It does not clarify. Heavy product users will see buildup within three weeks, guaranteed.

It does not control frizz in high humidity. The Smooth version performs better here, but even that fades by afternoon.

It does not suit very coarse type 4 coils on its own. The formula lacks the weight that thick textures need.

It does not offer a fragrance free option in the main range. Sensitive noses have no alternative within the line.

It does not last long in jumbo form for thick hair. Double cleansing drains a bottle faster than the label suggests.

Finally, the pump free cap wastes product. A pump version would fix the overdispensing problem entirely.

Pros And Cons Of Monday Shampoo

Pros

• Excellent price for the quality. Most bottles cost a fraction of salon brands while delivering similar slip and shine.
• Gentle cleansing base. Sodium cocoyl isethionate and cocamidopropyl betaine clean without stripping color or natural oils.
• Clear product targeting. Moisture, Volume, Smooth, Repair, and Clarify each solve one specific problem, so choosing is simple.
• Beautiful packaging. The matte pink bottles look premium on any shelf and the caps survive daily shower use.
• Cruelty free and vegan. Leaping Bunny approval and recyclable bottles support ethical shopping without a price increase.
• Strong lather for a sulfate free formula. A small amount covers full length hair easily.

Cons

• Silicones cause buildup. A clarifying wash becomes necessary every three to four weeks.
• No bond repair. Severely damaged hair needs a separate treatment product.
• Fragrance may irritate sensitive scalps. A small number of users report itching or redness.
• Weak on heavy product removal. Double cleansing is often required after styling products.
• Limited results on type 4 coily hair. Thicker textures need extra layers of moisture afterward.
• No pump option. The wide cap encourages overuse and waste.

Price And Value In 2026

Monday still holds its budget position in 2026. Standard bottles sit in the low single digit range in the United Kingdom and under ten dollars in most United States stores.

The jumbo 27 ounce bottles offer the best value per ounce. Two person households should buy those.

Amazon bundles the shampoo and conditioner together. The set usually costs less than two separate bottles.

Compare that to salon brands at four or five times the price. The performance gap is real but small for everyday hair.

Value depends on your hair, though. Fine hair users will stretch a bottle for two months. Thick, long hair users may finish one in five weeks.

Factor in the clarifying shampoo you will need. That adds a small extra cost to the routine.

The overall verdict on value stays positive. Few products at this price deliver comparable softness and shine.

Who Should Buy It And Who Should Skip It

Buy Monday if you have normal to dry hair that needs softness and shine. The Moisture version handles that job well.

Buy it if you have fine or oily hair that falls flat. The Volume version lifts roots convincingly.

Buy it if you want salon looking bottles without the salon receipt. The value proposition is genuinely strong.

Buy it if you follow color safe, cruelty free, or vegan shopping rules.

Skip it if your hair is severely damaged from bleach. You need bond repair first.

Skip it if you follow the strict curly girl method. The dimethicone breaks the rules.

Skip it if fragrance triggers your scalp. The scent is pleasant but present in every formula.

Skip it if you have very coarse type 4 hair and want a single product solution.

How To Use Monday Shampoo For Best Results

Start with fully saturated hair. Dry patches cause uneven cleansing and wasted product.

Use a coin sized amount for shoulder length hair. Fine hair needs less.

Apply at the scalp only. Massage with fingertips for thirty seconds. The suds running down the lengths clean them adequately.

Rinse completely with lukewarm water. Hot water opens the cuticle and dulls shine.

Double cleanse on wash days that follow heavy styling. The first pass removes product, and the second actually cleans.

Follow with the matching conditioner on mid lengths and ends. Skip the roots if you have oily hair.

Add a clarifying shampoo every three to four weeks. This single step prevents the buildup problem completely.

Pair Moisture with a weekly mask if your hair is coarse. Pair Volume with a lightweight leave in on the ends only.

Final Verdict

Monday shampoo earns its popularity. The formula cleans gently, smells lovely, and leaves hair soft for the price of a coffee.

It is not a miracle product. It smooths rather than repairs, and the silicones require a clarifying routine.

For everyday hair that just needs to look good, it competes with products costing four times more.

My rating sits at 4 out of 5 stars. The missing star goes to buildup and the lack of a fragrance free option.

Buy the Moisture version for dry hair. Buy the Volume version for fine hair. Buy the jumbo size to save money.

Patch test first if your scalp reacts easily. Keep a clarifying shampoo in the cabinet.

That combination gives you salon level results on a supermarket budget, which was the entire point of the brand.

Frequently Asked Questions

Is Monday shampoo good for colored hair?

Yes. The formula avoids SLS and SLES, the detergents that strip color fastest. My highlights showed no fading over four weeks. The pH balanced formula also keeps the cuticle closed, which helps pigment stay locked inside the strand.

Does Monday shampoo cause hair loss?

No evidence supports that claim. A small number of online reviewers report increased shedding, dryness, or scalp irritation. Those reports stay rare compared to total sales. Fragrance sensitivity is the most likely cause. Stop use and see a dermatologist if shedding increases.

Which Monday shampoo is best for frizzy hair?

Smooth is the right pick. It uses wheat protein and avocado oil to flatten the cuticle. Moisture also helps frizz through shea butter and hyaluronic acid. Pair either one with the matching conditioner for the best result in humid weather.

Is Monday shampoo curly girl approved?

Not fully. The sulfosuccinate cleanser is gentle enough for most curly routines. The dimethicone breaks strict curly girl rules because it is not water soluble. Loose wavy hair usually does fine. Tight curls following the method strictly should choose another brand.

How often should I use Monday shampoo?

Two or three times per week suits most hair types. Oily scalps can wash every other day with the Volume version. Dry or coily hair can stretch to once weekly with Moisture. Add a clarifying wash monthly to remove silicone buildup.
