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.

Weight on the hair Medium

Middle of the range — noticeable on fine hair, light on coarse hair.

Slip and detangling High

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

Water-binding (humectants) Low

Humectants appear, but low enough to be a minor part.

Oils and butters None

No oils or butters in the list.

Protein Minor

Protein appears, low enough to be a supporting ingredient.

Needs detergent to remove Yes

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

Fragrance Prominent

Fragrance sits in the first eight ingredients — a larger share of the formula.

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 (29)

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 · Aqua/Water/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 Cetearyl Alcohol
    General function

    A waxy fatty alcohol - nothing like drying alcohol. It gives conditioners their body and leaves a soft, smoothing film on the hair.

    Leading ingredient

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

    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.

    DependsFine or easily flattened hair

    Near the top of a conditioner it is doing most of the conditioning, and most of the weighting, at the same time.

    PubChem
    • fatty alcohol
    • emollient
    • thickener
  • 3 Amodimethicone
    General function

    A silicone modified to stick where hair is damaged, so it smooths selectively instead of coating everything. It resists rinsing more than plain dimethicone.

    Leading ingredient

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

    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

    Amino-functional silicone carries a positive charge, so it binds where the cuticle is worn rather than coating evenly. Damaged areas get most of it.

    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.

    International Journal of Trichology
    • silicone
    • conditioning agent
    • film former
  • 4 Cetyl Esters
    General function

    A waxy ester blend that replaces spermaceti in creams. It thickens and leaves a smooth, non-greasy finish.

    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

    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
    • thickener
  • 5 Behentrimonium Chloride
    General function

    A positively charged conditioning agent that binds to damaged, negatively charged spots on the hair. It is the main detangling ingredient in most rinse-out conditioners.

    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

    Electrokinetic measurement puts the C22 quat ahead of the C16 ones for deposition: the longer chain adds van der Waals stabilisation on top of the charge binding. That extra deposit is what coarse hair usually needs to comb through.

    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.

    DependsBuild-up-sensitive routines

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

  • Below about this point, order stops being meaningful — these are typically used at 1% or less.
  • 6 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.

    • fragrance
    • declared fragrance
  • 7 Pyrus Malus Fruit Extract/Apple Fruit Extract
    General function

    An extract from the fruit of Pyrus Malus. Plant extracts are used across a wide range of levels, and label order is the best guide to how much is here.

    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.

    • botanical extract
  • 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 Isopropyl Alcohol
    General function

    A fast-evaporating alcohol used as a solvent and to speed drying. Well down the list it is a processing aid; near the top it can leave hair feeling dry.

    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

    Evaporates on contact, which is how a spray sets almost instantly and leaves no weight behind it.

    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
  • 13 Niacinamide
    General function

    Vitamin B3, used in scalp products for conditioning claims.

    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.

  • 17 Cetrimonium Chloride
    General function

    A quick-acting conditioning agent that reduces static and combing force. It also helps keep the formula stable.

    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

    The C16 quat binds mostly by charge rather than by chain, so it deposits measurably less than the C22 ones. Less deposit is less conditioning and also less weight, which is usually the trade fine hair wants.

    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.

    General function

    A ceramide-like lipid used to reinforce the outer surface of damaged 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.

    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.

    Humectants bind water into the strand, and water — not oil — is what makes dry hair flexible instead of brittle.

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. 12 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 $9.99 is the price we have observed for the 12 oz. We need three stores before we call a price commonly seen.
  3. Good value under $27 comes from the 4 products we score as doing the same job as this one. A quarter of them cost less than $2.23/oz; at 12 oz that is $27. Under that line you are paying less than most of them.
  4. About $40 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 12 oz.

Claims check

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.
  • 4 sources consulted for this product (3 manufacturer or regulatory, 1 retailer, 0 editorial), last checked 2026-08-25.
  • Ingredient references are linked for 12 of 15 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.
