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 (25)

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 · Water (Aqua)
    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 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
  • 4 Sodium Chloride
    General function

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

    Supporting ingredient

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

    PubChem
    • salt
    • thickener
  • 5 Punica Granatum Seed Oil
    General function

    The oil pressed from Punica Granatum. How much weight a plant oil leaves depends on the hair it lands on; coarse hair tends to take more of it than fine 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

    Coats the surface and slows water leaving the strand, which is usually what coarse hair that dries out fast is missing.

    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 not suitFine or easily flattened hair

    Near the top of a list an oil is weight before it is anything else, and fine hair shows that first at the roots.

    • oil
    • emollient
  • 6 Camellia Oleifera Seed Oil
    General function

    Tea seed oil - light, fast-absorbing, used for shine on fine 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

    Coats the surface and slows water leaving the strand, which is usually what coarse hair that dries out fast is missing.

    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 not suitFine or easily flattened hair

    Near the top of a list an oil is weight before it is anything else, and fine hair shows that first at the roots.

    • oil
    • emollient
  • 7 Arginine
    General function

    An amino acid that holds water and carries a positive charge, so it is drawn to damaged spots on the strand.

    Supporting ingredient

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

    May suitVery dry or highly damaged hair

    Amino acids are the smallest protein fraction and bind water as well, so they add far less stiffness than a hydrolysed protein does.

    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.

    DependsProtein-sensitive hair

    The lightest option in the protein family, but still protein — worth watching if protein reliably stiffens your hair.

    PubChem
    • amino acid
    • humectant
  • 8 Lysine Hcl
    General function

    A salt form of the amino acid lysine, used in conditioning blends.

    Supporting ingredient

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

    May suitVery dry or highly damaged hair

    Amino acids are the smallest protein fraction and bind water as well, so they add far less stiffness than a hydrolysed protein does.

    DependsProtein-sensitive hair

    The lightest option in the protein family, but still protein — worth watching if protein reliably stiffens your hair.

    PubChem
    • amino acid
  • 9 Ethylhexyl Methoxycinnamate
    General function

    A UV filter added to protect the product's colour and, in leave-ins, to slow colour fade.

    Secondary ingredient

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

    May suitGray, silver, or brass-prone hair

    Sunlight oxidises hair pigment, and on gray, silver or lightened hair that shows up as yellowing. A UV filter on the label absorbs some of the light that drives it.

    PubChem
    • UV filter
  • 10 Hydrolyzed Keratin
    General function

    Fragments of the same protein hair is made of. They fill gaps on damaged strands and make hair feel firmer for a few washes.

    Secondary ingredient

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

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

    Filling surface gaps evens out the cuticle, which is part of what makes damaged hair comb and reflect light more like undamaged hair.

    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.

    May suitVery dry or highly damaged hair

    Size decides where it goes. In fibre testing, fractions around 221 and 2,577 Da reached the cortex while a 75,440 Da fraction stayed on the surface. A label prints the name, never the size, so a protein line is a claim about the ingredient rather than about the depth.

    International Journal of Cosmetic Science
    • film former
    • protein
    • hydrolysed protein
  • 11 Ceramide NG
    General function

    A lipid of the kind that sits naturally between cuticle scales, added to help hold a damaged surface together.

    Secondary ingredient

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

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

    Restoring surface lipids lowers friction between strands, which is where much of the roughness in damaged hair comes from.

    May suitProtein-sensitive hair

    A lipid, not a protein, despite sitting alongside proteins in most repair claims. It does not carry the stiffening effect.

    May suitVery dry or highly damaged hair

    Ceramides are the lipid class bleaching and heat deplete. Replacing them works on the surface layer rather than adding protein stiffness.

    PubChem
    • ceramide
    • emollient
  • Below about this point, order stops being meaningful — these are typically used at 1% or less.
  • 12 Fragrance · Fragrance (Parfum)
    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.

    • fragrance
    • declared fragrance
  • 13 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
  • 14 Sodium Benzoate
    • preservative
  • 15 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
  • 16 Coconut Acid
    • emulsifier
    • salt
  • 17 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
  • 18 Stearamidopropyl Dimethylamine
    General function

    A gentle conditioning agent activated by the acid in the formula. It smooths the cuticle without much build-up.

    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

    A cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.

    May suitVery dry or highly damaged hair

    The class that does the detangling in a conditioner. It deposits lubrication where the cuticle is worn.

    DependsBuild-up-sensitive routines

    Substantive by design. A routine with no detergent wash gives it nothing to leave with.

    PubChem
    • conditioning agent
  • 19 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
  • 20 PPG-9
    General function

    A light carrier that keeps a formula flexible and helps other ingredients spread.

    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

    Light and water-binding rather than oily, so it hydrates without contributing weight.

    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.

    • humectant
    • solvent
  • 21 Benzyl Alcohol

  • 22 Benzyl Salicylate
    General function

    A soft floral fragrance component listed separately as a recognised allergen.

How we work this out
  1. 28 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 28 oz at recognised stores — the cheapest quarter and the dearest quarter are left out, so one sale or one overpriced listing can’t move it.
  3. Good value under $42 comes from the 7 products we score as doing the same job as this one. A quarter of them cost less than $1.51/oz; at 28 oz that is $42. Under that line you are paying less than most of them.
  4. About $61 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 28 oz.

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.
  • 4 sources consulted for this product (3 manufacturer or regulatory, 1 retailer, 0 editorial), last checked 2026-08-25.
  • Ingredient references are linked for 14 of 20 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.
