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 (as stated) Medium

A medium hold, as stated by the brand.

Hold system Mixed

Gums and synthetic polymers together.

Cast risk Unlikely

Softening ingredients sit alongside the film formers, so a hard shell is unlikely.

Weight on the hair Medium

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

Oil absorption High

Absorbent powders or starches high in the list.

Oils and butters Present, high in the list

Oils sit high in the list — a softening, coating formula.

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 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 (24)

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/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 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 Polyquaternium-4
    General function

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

    Leading ingredient

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

    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
  • 4 Corn Starch Modified
    General function

    A modified starch. It soaks up oil and water and leaves a dry, slightly grippy feel, which is what puts starches in dry shampoos and texture products.

    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

    Adds grip and body with no oil attached, which is what lifts fine hair at the root instead of weighing it down.

    DependsMaximum-hold styling

    Starch gives texture and grip rather than a set film; firm hold usually needs a polymer alongside it.

    • starch
    • absorbent
  • 5 Propane
    General function

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

    Supporting ingredient

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

    PubChem
    • propellant
  • 6 Brassica Campestris (Rapeseed) Seed Oil · Canola Oil
    General function

    A light, inexpensive plant oil used as a base emollient.

    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 Salvia Hispanica (Chia) Seed Oil
    General function

    The oil pressed from Chia (Salvia Hispanica). 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
  • 8 Camellia Japonica Seed Oil · Camellia Japonica (Tsubaki) Seed Oil
    General function

    Camellia oil, light and 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
  • 9 Helianthus Annuus (Sunflower) Seed Oil
    General function

    A light, widely used oil that softens without much weight.

    Secondary ingredient

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

    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.

    DependsVery dry or highly damaged hair

    It works on the surface. In the comparison that established coconut oil's penetration, sunflower oil did not reduce protein loss from washing — its fatty acids are bulkier and less linear. It softens and smooths; it does not reinforce the fibre.

    International Journal of Trichology
    • oil
    • emollient
  • 10 Olea Europaea (Olive) Fruit Oil
    General function

    A heavy, coating oil traditionally used for deep conditioning.

    Secondary ingredient

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

    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.

    • oil
    • emollient
  • 11 Phospholipids
    General function

    Fat-and-water-loving lipids that help conditioning ingredients bind evenly to the strand.

    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

    Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.

    • emollient
    • emulsifier
  • 12 Benzophenone-4
    General function

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

    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
  • 13 Glycine Soja (Soybean) Oil
    General function

    A light plant oil used to soften and carry other oil-based ingredients.

    Secondary ingredient

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

    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.

    • oil
    • emollient
  • 14 Glycine Soja (Soybean) Sterols
    • amino acid
  • 15 Glycolipids
    General function

    Sugar-and-fat molecules used as gentle, fermentation-derived emulsifiers and cleansers.

    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

    Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.

    • emulsifier
    • emollient
  • 16 Laureth-4
    • emulsifier
  • 17 Peg-15 Cocomonium Chloride
    • emulsifier
  • ▾Below about this point, order stops being meaningful — these are typically used at 1% or less.
  • 18 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
  • 19 Sodium Hydroxide
    General function

    A strong base used in trace amounts to raise pH; fully neutralised in the finished product.

    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

    The alkali half of a pH-adjusting pair, used in small amounts to bring a formula up to its target rather than to make it alkaline. Alkaline conditions raise the fibre's surface charge and lift the scales — but the finished pH is not on the label.

    International Journal of Trichology
    • pH adjuster
  • 20 Phenoxyethanol
    • preservative
  • 21 Hexyl Cinnamal
    General function

    A jasmine-like fragrance component named separately as a recognised allergen.

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. 5.7 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 5.7 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 $13 comes from the 7 products we score as doing the same job as this one. A quarter of them cost less than $2.20/oz; at 5.7 oz that is $13. Under that line you are paying less than most of them.
  4. About $17 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 5.7 oz.

Formula

Formula score
9 of 10

It costs more per ounce than 81% of the 138 mousses we’ve priced, and the formula carries the systems the format is built around. Nothing in our library comes close enough on formula to be a cheaper substitute.

How the score is counted
  • Nothing in our library does the same job at a lower price
  • Costs more per ounce than 81% of the 138 mousses we’ve priced
  • Covers 5 of the 6 things a mouss should do
  • Reviewers mention 3 things they like about how it performs

  • A humidity claim with a mechanismThe claim has a film former or silicone behind it.1 pt
  • Fragrance kept out of the top eightScent as a finishing touch, not a major share.1 pt

The formula score is completeness for the job: the share of the systems this product type is normally built around that we can find in this list, weighted. It is not efficacy, not quality, and it never compares across product types.

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.
  • 2 sources consulted for this product (1 manufacturer or regulatory, 1 retailer, 0 editorial), last checked 2026-08-27.
  • Ingredient references are linked for 7 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 2026-08-27.
