How much cleansing you need depends on how fast your scalp gets oily, how much product you layer and your water. The consultation works that 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) High

Humectants near the top: binding water is one of its main jobs.

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 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. The 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 (23)

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 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.

    Indian Journal of Dermatology
    • amphoteric cleanser
    • secondary cleanser
    • cleanser
  • 3 Decyl Glucoside
    General function

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

    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 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.

    PubChem
    • nonionic cleanser
    • cleanser
  • 4 Sodium Cocoyl Isethionate
    General function

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

    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

    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
  • 5 Propylene Glycol
    General function

    A small humectant and solvent that keeps formulas stable and helps active ingredients spread.

    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

    Light and water-binding rather than oily, so it adds less weight than oils or butters do.

    May suitVery dry or highly damaged hair

    A small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.

    DependsClimate-sensitive or frizz-prone hair

    A humectant follows the air: it holds water in humid conditions and can give it up in very dry ones. Climate decides what it does more than the label does.

    PubChem
    • humectant
    • solvent
  • ▾Below about here, the order stops meaning much. These are usually used at 1% or less.
  • 6 Phenoxyethanol
    General function

    The most common modern preservative; it keeps the product free of bacteria and mould. It sits well below 1% of the formula.

    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
  • 7 Sodium Methyl Cocoyl Taurate
    General function

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

    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

    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.

    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
  • 8 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
  • 9 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.

    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 not suitFragrance-sensitive routines

    Declared fragrance. On a fragrance-sensitive routine this is the line that decides it, wherever it sits on the label.

  • 12 PEG-150 Distearate
    • thickener

  • 13 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.

    • conditioning agent
    • polymer
    • gum
  • 14 Potassium Sorbate
    • preservative
  • 15 Disodium EDTA
    General function

    Grabs metal ions from hard water so they cannot dull the hair or destabilise the formula.

    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.

    PubChem
    • hard-water chelator
  • 16 Polyquaternium-39
    General function

    A hold-and-condition polymer used in styling products for a soft set.

    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
  • 17 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.

    International Journal of Trichology
    • pH adjuster
    • hard-water chelator
  • 18 Polyquaternium-7
    General function

    A conditioning polymer that improves wet combing and adds body. Repeated use can build up on fine hair.

    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.

Where we’ve seen it2 listings · 2 stores

Sorted by price per ounce. Dated observations from our research, not live prices. Direct store pages, no affiliate links. We don’t sell this product.

How we work this out
  1. 9 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 9 oz. We need three stores before we call a price commonly seen.
  3. Good value under $18 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $1.98/oz; at 9 oz that is $18. Under that line you are paying less than most of them.
  4. About $31 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 9 oz.

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.

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.
  • 1 source consulted for this product (1 manufacturer or regulatory, 0 retailer, 0 editorial), last checked 2026-09-05.
  • Ingredient references are linked for 9 of 16 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 2026-09-06.
