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

Removes oil, buildup, and most residue — a reset wash.

Expected lather High

Thick foam that spreads quickly through the hair.

Slip and detangling Little

Nothing here is built to reduce combing force.

Water-binding (humectants) High

Humectants near the top — water-binding is a headline mechanism here.

Scalp active None

No over-the-counter scalp active.

Hard-water defence None

No chelating agent in the list.

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.

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 (36)

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
    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 C14-16 Olefin Sulfonate
    General function

    A strong non-sulfate detergent used in "sulfate-free" shampoos. It cleans about as thoroughly as a sulfate despite the label difference.

    Leading ingredient

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

    May suitBuild-up-sensitive routines

    A strong detergent with no sulfate on the label. It removes deposited films about as completely as a sulfate does.

    May not suitVery dry or highly damaged hair

    Sulfate-free on the label is a naming fact, not a mildness one: this is an efficient detergent, and hair short of moisture can feel it.

    PubChem
    • olefin sulfonate cleanser
    • cleanser
  • 3 Cocamidopropyl Hydroxysultaine
    General function

    A mild co-cleanser that keeps foam stable in hard water.

    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

    One of the mildest detergent classes. It is usually there to let a formula lather without a harsher detergent doing the work.

    May not suitBuild-up-sensitive routines

    The mildest detergents are also the least complete: a routine that deposits films needs something stronger periodically.

    • amphoteric cleanser
    • secondary cleanser
    • cleanser
  • 4 Glycol Distearate
    General function

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

    Supporting ingredient

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

    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
  • 5 Panthenol
    General function

    Provitamin B5. It draws in water and penetrates the strand a little, which is why it is the standard ingredient for softness and shine claims.

    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

    It hydrates without adding oil or a film, which is the combination fine hair usually needs.

    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.

    May suitVery dry or highly damaged hair

    A humectant that also penetrates the cuticle, so it holds water inside the strand rather than only on the surface.

    PubChem
    • humectant
    • conditioning agent
    • vitamin
  • Below about this point, order stops being meaningful — these are typically used at 1% or less.
  • 6 Tocopherol
    General function

    Vitamin E. It keeps the oils in a formula from going rancid and is used at very low levels.

    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
    • antioxidant
    • vitamin
  • 7 Tocopheryl Acetate
    General function

    A stable form of vitamin E used to keep the oils in a formula from oxidising. It is used at fractions of a percent.

    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
    • antioxidant
    • vitamin
  • 8 Ascorbic Acid
    General function

    Vitamin C, used as an antioxidant and, in some treatments, to help remove mineral 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.

    Baobab oil, a medium-weight oil used in textured-hair conditioners.

    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

    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.

    General function

    A plant butter that is slightly lighter than shea, used in curl creams.

    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

    Coarse, porous hair loses water quickly and can carry the weight; a butter slows that loss more than a thin oil does.

    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.

    May suitVery dry or highly damaged hair

    A solid fat melts onto the strand at body temperature and stays there, which is the heaviest surface moisture-holding a formula can offer.

    • butter
    • emollient
  • 24 Sodium PCA
    General function

    A moisture-binding ingredient that occurs naturally in hair and skin.

    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

    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
  • 25 Lecithin
    General function

    A soy- or sunflower-derived lipid that helps conditioning ingredients spread evenly on the strand.

    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
    • emulsifier
    • emollient
  • 26 Silk Amino Acids
    General function

    Silk protein broken into amino acids, used for slip and shine rather than strength.

    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 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.

    • protein
    • amino acid
  • 27 Sodium Cocoyl Amino Acids
    General function

    An amino acid of the kind hair protein is built from. Small enough to sit inside the cuticle, and used for water binding rather than strength.

    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 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.

    • mild anionic cleanser
    • humectant
  • 28 Magnesium Aspartate
  • 29 Caffeine
    • active
  • 30 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.

    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

    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.

    Scientific Reports
    • humectant
  • 31 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.

    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

    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.

    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.

Where we’ve seen it1 listing · 1 store

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. 8.45 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 $45 is the price we have observed for the 8.45 oz. We need three stores before we call a price commonly seen.
  3. Good value under $25 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $2.99/oz; at 8.45 oz that is $25. Under that line you are paying less than most of them.
  4. About $33 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 8.45 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.
  • 5 sources consulted for this product (5 manufacturer or regulatory, 0 retailer, 0 editorial), last checked 2026-08-25.
  • Ingredient references are linked for 11 of 17 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.
  • Formula readings: derivation v22. Record last updated 2026-08-25.
