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 High

Thick foam that spreads quickly through the hair.

Slip and detangling High

Conditioning agents sit high in the list — this is a detangling formula.

Water-binding (humectants) None found

No humectants found — nothing here pulls water into the hair.

Scalp active zinc pyrithione, 1%

Carries an over-the-counter scalp active, listed under Drug Facts.

Hard-water defence None

No chelating agent in the list.

Needs detergent to remove Yes

Water-insoluble silicones or waxes: a detergent wash is what removes them.

Protein None

No protein or amino acids in the list.

Fragrance Present

Fragrance is listed; it sits below the working ingredients.

Ingredients that matter

The ingredients that change a decision

The workhorse ingredients plus anything lower down that changes a decision. These chips name what an ingredient does — they are not safety scores, and no ingredient here is rated good or bad on its own.

Full ingredient list (20)

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 Zinc Pyrithione · Pyrithione Zinc
    General function

    An over-the-counter anti-dandruff active that reduces the yeast associated with flaking. Its percentage is stated in the drug facts panel.

    Leading ingredient

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

    PubChem
    • active
  • 2 Sodium Chloride
    General function

    Table salt. In shampoo it is used to thicken the liquid, not to treat the hair.

    Leading ingredient

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

    PubChem
    • salt
    • thickener
  • 3 Water
    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
  • 4 Cocos Nucifera (Coconut) Oil
    General function

    One of the few oils small enough to move into the strand, which is why it is used for pre-wash treatments. It can feel heavy or stiff on protein-sensitive hair.

    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

    Because it penetrates rather than sits on top, it works on hair that loses water through a worn cuticle instead of only slowing evaporation from the surface the way a non-penetrating oil does.

    May suitFrizz-prone, damaged, or high-friction hair

    A thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.

    May suitVery dry or highly damaged hair

    The exception to the class read: lauric acid is small and linear enough to enter the shaft rather than only coat it, and in comparison testing coconut oil was the one that reduced protein loss from washing on both undamaged and damaged hair.

    International Journal of Trichology
    • oil
    • emollient
  • 5 Sodium Laureth Sulfate
    General function

    A strong, high-foaming cleanser and the most common shampoo detergent. It removes oil and product efficiently, which can be more than dry or colour-treated hair wants.

    Supporting ingredient

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

    May suitBuild-up-sensitive routines

    A sulfate detergent removes deposited silicone, wax and styling films in one wash, which is what resets a routine before build-up is visible.

    May suitFine or easily flattened hair

    Fine hair that goes limp under conditioning films usually reads a full detergent wash as volume returning.

    May not suitDry, coarse, or high-porosity hair

    Coarse and high-porosity hair loses water quickly on its own; an efficient detergent removes the surface oils that were slowing that down.

    Indian Journal of Dermatology
    • sulfate cleanser
    • cleanser
  • 6 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.

    Supporting ingredient

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

    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.

    • conditioning agent
    • polymer
    • gum
  • 7 Dimethicone
    General function

    The most common conditioning silicone. It coats the strand for shine, slip, and frizz control, and needs a detergent (not just water) to wash out.

    Supporting ingredient

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

    May suitClimate-sensitive or frizz-prone hair

    A surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.

    May suitFrizz-prone, damaged, or high-friction hair

    Lays a smooth film along the cuticle, which lowers combing friction and flattens the surface irregularities that read as frizz.

    May not suitBuild-up-sensitive routines

    Dimethicone does not disperse in water. On a routine that skips detergent it stays on the hair and accumulates wash after wash.

    • silicone
    • emollient
    • conditioning agent
  • Below about this point, order stops being meaningful — these are typically used at 1% or less.
  • 8 Sodium Benzoate
    General function

    A food-grade preservative that works only in acidic formulas, which is why it usually appears alongside citric acid.

    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.

    PubChem
    • preservative
  • 9 Zinc Carbonate
    • mineral
  • 10 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.

    • conditioning agent
    • film former
    • polymer
  • 11 Glycol Distearate
    General function

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

    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 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
  • 12 Stearyl Alcohol
    General function

    A fatty alcohol that thickens conditioners and helps them coat the hair evenly.

    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

    The waxy solid that gives a conditioner its body. It deposits a soft lubricating layer, which is most of what makes hair feel smooth after rinsing.

    May suitFrizz-prone, damaged, or high-friction hair

    Deposits with the cationic conditioners and helps them lie flat along the strand, which is where the detangling actually comes from.

    PubChem
    • fatty alcohol
    • emollient
    • thickener
  • 13 Cocamide MEA
    General function

    A coconut-derived thickener that stabilises foam and gives shampoo its body.

    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

    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.

    • secondary cleanser
    • nonionic cleanser
    • thickener
  • 14 Magnesium Carbonate Hydroxide
  • 15 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.

    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

    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.

    • amphoteric cleanser
    • secondary cleanser

  • 16 Cetyl Alcohol
    General function

    A fatty alcohol used to thicken creams and add slip. It softens rather than dries.

    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

    The waxy solid that gives a conditioner its body. It deposits a soft lubricating layer, which is most of what makes hair feel smooth after rinsing.

    May suitFrizz-prone, damaged, or high-friction hair

    Deposits with the cationic conditioners and helps them lie flat along the strand, which is where the detangling actually comes from.

    • solubilizer
  • 18 Methylchloroisothiazolinone
    • isothiazolinone
    • preservative
  • 19 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.

    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.

How we work this out
  1. 13.5 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.
  2. Seen at $8.99 is the price we have observed for the 13.5 oz. We need three stores before we call a price commonly seen.
  3. Good value under $6 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $0.41/oz; at 13.5 oz that is $6. Under that line you are paying less than most of them.
  4. About $7 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 13.5 oz.

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 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.
  • 6 sources consulted for this product (3 manufacturer or regulatory, 2 retailer, 1 editorial), last checked 2026-08-25.
  • Ingredient references are linked for 6 of 11 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.
