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.

Hold system Synthetic polymer

Synthetic hold polymers — the firmest of the hold systems.

Cast risk Likely

Film formers without much softening them — expect a cast to scrunch out.

Weight on the hair Light

Water-first and light: unlikely to flatten fine hair.

Oil absorption None

No absorbent powders or starches.

Oils and butters None

No oils or butters in the list.

Fast-drying alcohol None

No fast-drying alcohol in the list.

Needs detergent to remove No

Nothing here needs a detergent wash to remove.

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 (12)

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 Isobutane
    General function

    A pressurised gas that pushes an aerosol out of the can and evaporates on contact.

    Leading ingredient

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

    PubChem
    • propellant
  • 3 Propane
    General function

    An aerosol propellant, usually blended with butane to set the spray pressure.

    Leading ingredient

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

    PubChem
    • propellant
  • 4 Polyquaternium-4
    General function

    A cellulose-based hold polymer used in gels and sprays for flexible set.

    Supporting ingredient

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

    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
  • ▾Below about this point, order stops being meaningful — these are typically used at 1% or less.
  • 5 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
  • 6 Propylene Glycol
    General function

    A small humectant and solvent that keeps formulas stable and helps active 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.

    PubChem
    • humectant
    • solvent
  • 7 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
  • 8 C9-11 Pareth-8
    General function

    A fatty alcohol with ethylene oxide added. The number is how many units: low numbers sit on the oil side of an emulsion, high numbers dissolve in water.

    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.

    • emulsifier
  • 9 Caprylyl Glycol
    General function

    A gentle preservative helper that also holds a little moisture.

    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

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

    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.

    PubChem
    • preservative
    • humectant
  • 10 1,2-Hexanediol
    General function

    A preservative booster that also holds a little moisture and helps other ingredients dissolve.

    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.

    PubChem
    • preservative
    • humectant
    • solvent
  • 11 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
  • 12 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.

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. 6.8 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 $4.99 is the price we have observed for the 6.8 oz. We need three stores before we call a price commonly seen.
  3. Good value under $7 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $1.08/oz; at 6.8 oz that is $7. Under that line you are paying less than most of them.
  4. About $9 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 6.8 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 to read this

We look at the first 10–15 ingredients and what they do in a formula — not marketing. If the list doesn't speak to a claim, we don't assume.

Reviewers

What people report

Recurring themes our researchers wrote in their own words from sourced reviews. We do not store or scrape star ratings.

Many reviewers describe the product as defining curls without adding crunch or noticeable texture buildup.

A recurring question among buyers is whether the mousse leaves curls feeling sticky, which the brand's own reply addresses directly, suggesting stickiness is a common worry among curl-focused shoppers.

Several reviewers say the foam collapses quickly and the brand itself advises diffusing or trying a heavier-hold alternative if that happens.

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 (1 manufacturer or regulatory, 0 retailer, 3 editorial), last checked 2026-09-13.
  • Ingredient references are linked for 5 of 7 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 2026-09-13.
