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 High

Thick foam that spreads quickly through the hair.

Slip and detangling Some

Some slip, mostly from esters or silicones rather than conditioners.

Water-binding (humectants) Moderate

Humectants in the working part of the formula.

Scalp active salicylic acid, 3%

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

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.

Cocamidopropyl Betaine amphoteric cleanser — Cleanses

What the list leaves out, and what it carriesNo silicones or drying alcohols. Protein-free: this is built for moisture rather than for strengthening. Contains fragrance. An over-the-counter scalp active is listed (salicylic acid 3%).
Full ingredient list (13)

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
    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 Ammonium Lauryl Sulfate
    General function

    A sulfate detergent similar in strength to sodium lauryl sulfate, used for fast, high foam.

    Leading ingredient

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

    May suitBuild-up-sensitive routines

    A sulfate detergent can lift deposited silicone, wax and styling films, 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.

    PubChem
    • sulfate cleanser
    • cleanser
  • ▾Below about here, the order stops meaning much. These are usually used at 1% or less.
  • 4 Potassium Hydroxide
    General function

    A strong base used in trace amounts to set pH; it is fully neutralised in the finished product.

    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.

    DependsFrizz-prone, damaged, or high-friction hair

    pH adjusters are how a formula is brought to a chosen acidity, and an acidic formula keeps the cuticle lying flatter than an alkaline one. Which way this one moves the pH depends on the formula, and the finished pH is not on the label.

    PubChem
    • pH adjuster
  • 5 Glyceryl Caprylate/Caprate
    General function

    A fatty ester. Esters give slip and a smooth after-feel; lighter ones read dry and silky, heavier ones read rich.

    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

    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
  • 6 Aloe Barbadensis Leaf Juice
    General function

    Aloe gel, used for light moisture and slip. High in the list it also contributes a little natural hold.

    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 suitFine or easily flattened hair

    Hydration with no oil attached, so it adds very little weight even high on a list.

    May suitVery dry or highly damaged hair

    Aloe is mostly water carrying sugars that bind more of it, which is why it turns up as the base of moisture-first formulas.

    • humectant
    • botanical extract
    • gum
  • 7 Niacinamide
    General function

    Vitamin B3, used in scalp products for conditioning 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 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.

    PubChem
    • vitamin
    • conditioning agent
  • 8 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.

    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
  • 9 Tocopheryl Acetate
    • antioxidant
    • vitamin
  • 10 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
  • 11 Hydroxyacetophenone
    • preservative
    • antioxidant
  • 12 Sodium Citrate
    General function

    Used with citric acid to hold the formula at a steady, slightly acidic pH. It also binds a little hard-water mineral.

    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
    • pH adjuster
    • hard-water chelator
  • 13 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.

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. and 1 listing we don’t count, from grey-market or unverified sellers.

How we work this out
  1. 11 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. Commonly seen is the middle half of current prices for the 11 oz at recognised stores. We leave out the cheapest and most expensive quarters, so one sale or one overpriced listing can’t move it.
  3. Good value under $31 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $2.81/oz; at 11 oz that is $31. Under that line you are paying less than most of them.
  4. About $38 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 11 oz.

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.
  • 7 sources consulted for this product (2 manufacturer or regulatory, 1 retailer, 4 editorial), last checked 2026-10-22.
  • Ingredient references are linked for 6 of 10 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 2026-10-07.
