What the formula actually does

Read from the label, not the marketing

Each row says where it comes from: F means we derived it from this product’s own ingredient list, S means it is a claim the brand makes that the formula neither confirms nor contradicts.

Cleansing strength Strong

A reset wash that removes oil, buildup, and most residue.

Expected lather Moderate

An ordinary shampoo lather.

Slip and detangling Moderate

Conditioning agents are present, lower in the list.

Water-binding (humectants) Low

Humectants appear, but low enough to be a minor part.

Scalp active None

No over-the-counter scalp active.

Hard-water defence Chelators present

Contains chelators, which bind hard-water and pool minerals.

Needs detergent to remove No

Nothing here needs a detergent wash to remove.

Protein Minor

Protein appears, low enough to be a supporting ingredient.

Fragrance Present

Fragrance is listed; it sits below the working ingredients.

Full ingredient list (50)

In the US, ingredients above 1% are listed from most to least. Below 1% they can appear in any order. Each note keeps three things apart: what the ingredient generally does, its role in this type of product, and what its position can tell you.

1 Water · Water/Aqua/Eau

General function
The base of almost every rinse-off and cream hair product. It carries everything else and is normally the first ingredient on the label.

Leading ingredient
Listed in the first three ingredients, it is likely a structural part of this formula.
- solvent
2 Sodium Cocoyl Isethionate

General function
A mild cleanser that gives a creamy lather and leaves hair less stripped than sulfates.

Leading ingredient
Listed in the first three ingredients, it is likely a structural part of this formula.

May suitCurls or waves needing flexible hold
The detergent class most curl routines are built around: it lathers and cleanses without stripping the strand back to bare.

May suitDry, coarse, or high-porosity hair
A gentler detergent leaves more of the surface oil that slows water loss from coarse or porous hair.

May suitVery dry or highly damaged hair
Cleanses with less sebum removal than a sulfate detergent, so hair that is short of moisture keeps more of it through the wash.
- mild anionic cleanser
- cleanser
3 Sodium Lauroyl Methyl Isethionate

General function
A gentle, dense-lathering cleanser used as the primary detergent in many sulfate-free shampoos.

4 Potassium Cocoyl Glycinate

General function
A mild cleanser built on a coconut- or plant-derived fatty acid. Cleansers of this family lather less aggressively than a sulfate and leave hair less stripped.

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
PubChem

5 Glycol Distearate

General function
A wax that gives shampoo its pearly look and a slightly richer feel.

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

May suitFrizz-prone, damaged, or high-friction hair
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.

PubChem
- opacifier
- emollient
6 Cocamidopropyl Betaine

General function
A mild coconut-derived co-cleanser that boosts foam and softens the effect of stronger detergents. It appears in most shampoos, gentle or not.

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

May suitDry, coarse, or high-porosity hair
Mild cleansing leaves more surface lubrication in place on hair that dries out quickly.

May not suitBuild-up-sensitive routines
The mildest detergents are also the least complete: a routine that deposits films needs something stronger periodically.

DependsVery dry or highly damaged hair
Among the mildest detergents in use — it is what baby shampoos are built on — but it is almost always the second detergent in a formula. How much a wash strips is still decided by the primary detergent listed above it.

7 Capryloyl/Caproyl Methyl Glucamide

General function
A sugar-derived cleanser, mild and readily biodegradable, used in gentle wash bases.

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

May suitBuild-up-sensitive routines
Cleansing is what lifts deposited films off the strand. How completely depends on which detergent it is and how high on the list it sits.

DependsVery dry or highly damaged hair
Every detergent removes some sebum along with the product it is there to wash out. Which detergent it is matters more than that there is one.

8 Lauryl Lactyl Lactate

General function
A plant-derived ester used for conditioning slip with a light feel.

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

May suitFine or easily flattened hair
A light emollient: it softens the surface with noticeably less weight than an oil or a butter.

May suitFrizz-prone, damaged, or high-friction hair
Spreads thin and lowers friction between strands without the heaviness of a fixed oil.
- light ester
- emollient
- conditioning agent
9 Acrylates Copolymer

General function
A hold polymer that forms a firm, humidity-resistant film. It is the usual source of a hard cast in gels.

Secondary ingredient
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.

May suitClimate-sensitive or frizz-prone hair
A set polymer film is a physical barrier to humidity, so a style keeps its shape longer in damp conditions.

May suitMaximum-hold styling
Synthetic film formers dry into a continuous film, which is what holds a shape against movement and against humid air.

DependsBuild-up-sensitive routines
Some acrylate copolymers rinse with water and some need a detergent; the label alone does not say which one a formula used.

May suitVery dry or highly damaged hair
A sugar-derived non-ionic detergent, among the gentlest in use. It cleanses with little foam of its own and little sebum removal.

May not suitBuild-up-sensitive routines
Gentle cleansing leaves water-insoluble deposits largely in place; they come off with a stronger wash, not this one.

15 Glycerin

General function
Glycerin, also called glycerol, attracts moisture and mixes completely with water.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitDry, coarse, or high-porosity hair
High-porosity hair loses water fast; a humectant holds some of it in place for longer than the wash itself would.

May suitVery dry or highly damaged hair
Binds water into the outer layers of the strand, and water is what makes dry hair flexible again rather than brittle.

DependsClimate-sensitive or frizz-prone hair
Water moves both ways. Measured across concentrations, glycerin solutions give water up in some conditions and take it from the air in others. What it does for you depends on how much of it is there and on the air around it.

Scientific Reports
- humectant
16 Citric Acid

General function
Used to bring the product to a slightly acidic pH, which helps the cuticle lie flat. It is almost always near the end of the list.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitBuild-up-sensitive routines
Holds hard-water minerals in solution so they rinse away instead of depositing on the hair.

May suitFrizz-prone, damaged, or high-friction hair
The acid side of pH adjustment, and the reason it matters is measured: alkaline formulas raise the fibre's surface negative charge, increase friction between strands and lift the scales, while lower-pH ones do the reverse.

May suitGray, silver, or brass-prone hair
Where a warm cast comes from water minerals rather than from the hair itself, holding those metals in solution is what removes it.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitBuild-up-sensitive routines
Binds the calcium and magnesium in hard water, which is what stops mineral deposits accumulating on the strand wash after wash.

May suitGray, silver, or brass-prone hair
Copper and iron carried in tap water deposit on the strand and read as a dull, warm cast on gray or light hair. A chelator holds those metals in solution so the wash carries them off.

20 Polyquaternium-10

General function
A cellulose-based conditioning polymer that leaves a thin, static-reducing film. Very common in shampoos as the ingredient that keeps them from stripping.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitCurls or waves needing flexible hold
Cationic polymers hold a curl loosely and stay soft, which is why they turn up in definition products rather than firm-hold ones.

May suitFrizz-prone, damaged, or high-friction hair
A cationic polymer stays on the hair through rinsing, which is what keeps static and combing friction down after the wash.

May suitMaximum-hold styling
Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.

21 Panthenol

General function
Provitamin B5. It draws in water and penetrates the strand a little, which is why it is the standard ingredient for softness and shine claims.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitFine or easily flattened hair
It hydrates without adding oil or a film, which is the combination fine hair usually needs.

May suitFrizz-prone, damaged, or high-friction hair
Deposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.

May suitVery dry or highly damaged hair
A humectant that also penetrates the cuticle, so it holds water inside the strand rather than only on the surface.

22 Sodium PCA

General function
A moisture-binding ingredient that occurs naturally in hair and skin.

Estimated lower-concentration zone

DependsFrizz-prone, damaged, or high-friction hair
The alkali half of a pH-adjusting pair, used in small amounts to bring a formula up to its target rather than to make it alkaline. Alkaline conditions raise the fibre's surface charge and lift the scales — but the finished pH is not on the label.

How we work this out

10.2 oz is the size stores list most often; every comparison on this page is made at it. Other sizes are shown in the Sizes row and the store list.
Seen at $16 is the price we have observed for the 10.2 oz. We need three stores before we call a price commonly seen.
Good value under $28 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $2.78/oz; at 10.2 oz that is $28. Under that line you are paying less than most of them.
About $44 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 10.2 oz.

Final decision

Should you buy it?

A solid pick for the hair it suits

Best user

Colour-treated hair, for washing without sulfates and a proper reset wash

Biggest tradeoff

Less suited to anyone sensitive to fragrance, dry or damaged hair, or anyone who wants to pick it up locally

Best alternative if not

Nothing in our library matches it closely at a lower price.

We do not sell products or take placement fees. This page states what the formula and the prices show; the consultation is what matches it to a person.

Claims check

What the brand says, and what the formula shows

Claims are quoted from the brand. We mark a claim supported, partly supported or conflicting only when the ingredient list speaks to it. Everything else stays "stated by the brand". That isn’t a criticism: most claims can’t be checked from a label.

SupportedBacked by ingredients

Partly supportedSome supporting logic

Stated by brandNo clear evidence

Potential conflictFormula works against claim

Helps prevent breakage

Protein or ceramides are present, but low enough that this reads as support, not treatment.

Polyquaternium-10

Partly supported

Supports the surface, not a treatment.

Volumizes and nourishes

A mid-weight formula: it will not flatten fine hair, but lift is not its main job.

Acrylates Copolymer
Polyquaternium-10

Partly supported

Neutral on lift.

Fights DHT

This is a marketing claim; an ingredient list cannot speak to it.

Stated by brand

Can’t be confirmed from label.

Strengthens hair strands

Protein or ceramides are present, but low enough that this reads as support, not treatment.

Polyquaternium-10

Partly supported

Supports the surface, not a treatment.

Nourishes scalp for thicker-looking hair

Humectants and emollients are present, but lower in the list than the claim implies.

Glycol Distearate
Lauryl Lactyl Lactate
Glycerin

Partly supported

Some hydration, at a low level.

How to read this

We look at the first 10–15 ingredients and what they do in a formula, not at the marketing. If the list doesn't speak to a claim, we don't assume.

How this page was made

Everything above comes from our researched product record: identity, the ingredient list as printed, the brand's own claims, dated prices and review themes our researchers wrote in their own words. No part of this page is written by hand for one product.
The value band is a fixed label over two stored numbers: this product’s cost per ounce as a percentile of every product of this type we have priced, each at the size it is most often sold in, and how many products we score as doing the same job cost at least a quarter less per ounce.
Both scores out of ten are defined on this page. The formula score is completeness for the job, computed from a fixed per-format checklist shown beneath the gauge; the price score is cost per ounce against every product of this type we have priced.
The "Is this right for you?" panel reads only your own consultation answers, and it applies exactly the filters our recommendation engine applies. It is computed when you load the page and is never stored on it.
3 sources consulted for this product (1 manufacturer or regulatory, 0 retailer, 2 editorial), last checked 2026-09-17.
Ingredient references are linked for 18 of 30 product-aware annotations on this page. Fit notes are general formulation guidance. They aren’t a verdict on the finished product or on you.
We haven’t tested this product in a lab, and we don’t physically test your hair. Formula readings come from the ingredient list. Claims about how it behaves are labelled as the brand's.
Ingredient order tells you relative amount only above roughly 1%. Prices are what we saw on the dates shown and can change.
Ingredient names link to our ingredient library, where each entry shows what it does, which product types use it, and where it usually sits on a label across everything we have researched.
This is cosmetic information, not medical advice, and nothing here diagnoses or treats a health condition.
Formula readings: derivation v23. Record last updated 2026-09-17.
