Whether this much cleansing is right for you depends on how fast your scalp oils, how much product you layer, and your water — that is what the consultation works out.

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 Moderate

Removes oil and product; leaves some conditioning behind.

Expected lather Moderate

An ordinary shampoo lather.

Slip and detangling Moderate

Conditioning agents are present, lower in the list.

Water-binding (humectants) Moderate

Humectants in the working part of the formula.

Scalp active None

No over-the-counter scalp active.

Hard-water defence Chelators present

Chelators are present — they 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 (38)

US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order. Annotations keep three readings separate: the ingredient's general function, its role in this product type, and what its position can support.

1 Water · Aqua (Water, 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 Methyl Cocoyl Taurate

General function
A mild cleanser that keeps foaming in hard water and rinses cleanly.

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 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.

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

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.

4 Decyl Glucoside

General function
A sugar-derived, low-foam cleanser used in gentle and curly-method shampoos.

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 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.

5 Sodium Methyl 2-Sulfolaurate

General function
A mild cleanser that foams well in hard water, usually paired with disodium 2-sulfolaurate.

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.

6 PEG-120 Methyl Glucose Trioleate

General function
A sugar-derived thickener used to give sulfate-free cleansers body.

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

General function
A sugar-beet derived humectant that binds water. Despite the name it is not a cleanser like cocamidopropyl betaine.

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
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
A humectant moves water in whichever direction the air allows: it holds moisture in humid conditions and can pull it back out of hair in very dry ones.

PubChem
- humectant
8 Glycerin

General function
A small water-loving molecule that draws moisture into the hair and holds it there. It is the most common softening ingredient in conditioners and leave-ins.

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
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.

9 Lauryl Glucoside

General function
A mild sugar-derived cleanser with a soft, low lather.

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

11 Fragrance · Parfum (Fragrance)

General function
An undisclosed blend of scent ingredients. Regulations let it stay unlisted, so a fragrance-free product is the only way to be certain what is not in it.

May suitCurls or waves needing flexible hold
A polysaccharide film stays softer than a synthetic one as it dries, which is what leaves a curl defined but still able to move.

May suitFrizz-prone, damaged, or high-friction hair
A soft film binds neighbouring strands together, which is most of what keeps flyaways lying down without stiffness.

May not suitMaximum-hold styling
Gum films stay soft. A style that needs firm fixation usually wants a synthetic polymer doing the holding.

14 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.

16 Dioleoylethyl Hydroxyethylmonium Methosulfate
17 Guar Hydroxypropyltrimonium Chloride

General function
A conditioning polymer made from guar bean gum. It deposits during rinsing, which is why sulfate shampoos can still leave hair soft.

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
Gums thicken and set soft, which gives definition that bends rather than a rigid cast.

May suitFrizz-prone, damaged, or high-friction hair
Cationic conditioners bind to the negatively charged damaged cuticle, laying it flat and cutting the friction that causes combing breakage.

May suitMaximum-hold styling
A styling polymer dries into a film across the strands, which is what makes a shape hold instead of relax.

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.

May suitFine or easily flattened hair
Adds grip and body with no oil attached, which is what lifts fine hair at the root instead of weighing it down.

DependsCurls or waves needing flexible hold
How rigid the finish is depends on which polymer it is and what the formula pairs with it, not on there being one.

How we work this out

10.1 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 $23.19 is the price we have observed for the 10.1 oz. We need three stores before we call a price commonly seen.
About $15 is what shampoos typically cost at this size. Too few of the products that do the same job carry a price for us to draw a good-value line.

Claims check

What the brand says, against what the formula shows

Claims are quoted from the brand. We only mark one supported, partly supported, or conflicting when the ingredient list actually speaks to it; everything else stays "stated by the brand", which is not a criticism — most claims simply cannot be read off a label.

How to read this

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

How this page was made

Everything above is generated from our researched product record — identity, the ingredient list as printed, the brand's own claims, dated price observations, and review themes written in our researchers' own words. No part of this page is written per 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 (0 manufacturer or regulatory, 0 retailer, 3 editorial), last checked 2026-09-17.
Ingredient references are linked for 18 of 29 product-aware annotations on this page. Fit notes are conditional formulation guidance, not a conclusion about the finished product or about you.
We have not tested this product in a lab and we do not physically test your hair. Formula readings come from the ingredient list; behaviour claims are labelled as the brand's.
Ingredient order tells you relative amount only above roughly 1%. Prices are observations on the dates shown and change without notice.
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.
