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 Some

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

Needs detergent to remove Yes

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

Water-binding (humectants) Moderate

Humectants in the working part of the formula.

Fast-drying alcohol High in the list

Fast-drying alcohol in the first three ingredients.

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 (19)

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 · 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 Alcohol Denat. · ALCOHOL DENAT
    General function

    Fast-drying alcohol used to make sprays set quickly. In leave-on products it can leave hair feeling dry, especially in high position on the list.

    Leading ingredient

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

    May suitFine or easily flattened hair

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

    May not suitDry, coarse, or high-porosity hair

    Porous hair gives water up easily as it is; a fast-evaporating solvent high on the list accelerates that.

    May not suitVery dry or highly damaged hair

    It evaporates quickly and takes some water with it. On hair already short of moisture, a formula built on a lot of it can finish drier than it started.

    PubChem
    • drying alcohol
    • solvent
  • 3 VA/Crotonates/Vinyl Neodecanoate Copolymer
    General function

    A hairspray polymer that holds firmly and resists humidity.

    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 set polymer film is a physical barrier to humidity, so a style keeps its shape longer in damp conditions.

    May suitMaximum-hold styling

    Synthetic film formers dry into a continuous film, which is what holds a shape against movement and against humid air.

    DependsBuild-up-sensitive routines

    Some acrylate copolymers rinse with water and some need a detergent; the label alone does not say which one a formula used.

    • film former
    • polymer
  • 4 Octylacrylamide/Acrylates/Butylaminoethyl Methacrylate Copolymer · OCTYLACRYLAMIDE/ ACRYLATES/BUTYLAMINOETHYL METHACRYLATE COPOLYMER
    General function

    A firm hold polymer used in hairsprays and gels. It holds well in humidity and brushes out.

    Supporting ingredient

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

    May suitClimate-sensitive or frizz-prone hair

    A set polymer film is a physical barrier to humidity, so a style keeps its shape longer in damp conditions.

    May suitMaximum-hold styling

    Synthetic film formers dry into a continuous film, which is what holds a shape against movement and against humid air.

    • film former
    • polymer
  • 5 Crotonic Acid/Vinyl C8-12 Isoalkyl Esters/Va/Bis-Vinyldimethicone Crosspolymer
    General function

    A synthetic film-forming polymer. Polymers of this kind dry to a continuous film on the hair, which is how a styling product holds a shape.

    Supporting ingredient

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

    • film former
    • polymer
    • silicone
  • ▾Below about here, the order stops meaning much. These are usually used at 1% or less.
  • 6 Aminomethyl Propanol
    General function

    A base used in trace amounts to neutralise acidic hold polymers so they thicken and set properly.

    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
  • 7 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
  • 8 PEG-40 Hydrogenated Castor Oil
    General function

    A castor-oil derivative that dissolves fragrance and oils into water so the product stays clear and does not separate.

    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.

    • solubilizer
    • emulsifier
  • 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.

    • fragrance
    • declared fragrance
  • 10 Xylose
    General function

    A plant sugar used as a light humectant, often alongside other sugar-derived moisturisers.

    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.

    • humectant
  • 11 Ethylhexylglycerin
    General function

    A preservative booster that also adds a little softness. Almost always paired with phenoxyethanol.

    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
    • preservative
    • emollient
  • 12 Benzophenone-4
    General function

    A UV filter added to keep the product itself, and dyed hair, from fading in light.

    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 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
  • 13 Limonene
    General function

    A citrus-smelling fragrance component that EU rules require to be named separately because some people react to 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

    One of the 26 scent components the EU requires to be named individually above a threshold. It is named because it is a known contact allergen, not because it is unusual.

Where we’ve seen it4 listings · 4 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. 4.2 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 4.2 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 $16 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $3.88/oz; at 4.2 oz that is $16. Under that line you are paying less than most of them.
  4. About $21 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 4.2 oz.

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.
  • 4 sources consulted for this product (2 manufacturer or regulatory, 0 retailer, 2 editorial), last checked 2026-10-31.
  • Ingredient references are linked for 9 of 14 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 2026-10-31.
