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 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 Some

Absorbents appear, low in the list.

Oils and butters Present, lower down

Oils are present, but low enough to be a finishing touch.

Fast-drying alcohol None

No fast-drying alcohol in the list.

Needs detergent to remove Yes

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

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 (41)

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 VP/VA Copolymer
    General function

    A hold polymer that dries to a clear film. It sets the style and washes out with water.

    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
  • 3 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
  • 4 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
  • 5 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.

    Supporting ingredient

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

    • solubilizer
    • emulsifier
  • 6 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.

    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

    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
  • 7 PVP
    General function

    A classic hairspray polymer. It gives firm hold but attracts moisture, so humidity can soften the set.

    Supporting ingredient

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

    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.

    May not suitClimate-sensitive or frizz-prone hair

    The film takes up water from the air. The patent work that produced the VP/VA copolymers describes a PVP film turning sticky after time in a humid atmosphere, and being dependable only where humidity is low — so hold and feel both move with the weather.

    PubChem
    • film former
    • polymer
  • 8 PEG-12 Dimethicone
    General function

    A water-soluble silicone that smooths without the build-up concern of standard silicones.

    Supporting ingredient

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

    May suitBuild-up-sensitive routines

    The PEG- and PPG-modified silicones disperse in water, so ordinary washing carries them off instead of leaving a film to accumulate.

    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

    Delivers the slip and surface smoothing of a silicone without needing a detergent wash to remove it afterwards.

    • emollient
    • silicone
    • water-soluble silicone
  • 9 Persea Gratissima (Avocado) Oil
    General function

    A rich oil used in masks and heavier creams for softness on coarse or dry hair.

    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
  • 10 Cocos Nucifera (Coconut) Oil
    General function

    One of the few oils small enough to move into the strand, which is why it is used for pre-wash treatments. It can feel heavy or stiff on protein-sensitive hair.

    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

    Because it penetrates rather than sits on top, it works on hair that loses water through a worn cuticle instead of only slowing evaporation from the surface the way a non-penetrating oil does.

    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 suitVery dry or highly damaged hair

    The exception to the class read: lauric acid is small and linear enough to enter the shaft rather than only coat it, and in comparison testing coconut oil was the one that reduced protein loss from washing on both undamaged and damaged hair.

    International Journal of Trichology
    • oil
    • emollient
  • 11 Simmondsia Chinensis (Jojoba) Seed Oil
    General function

    Not chemically an oil: about 97% of it is liquid wax esters, which is why it resists going rancid and sits close to the scalp's own sebum. It smooths without a heavy finish.

    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.

    May suitMaximum-hold styling

    A wax holds by staying solid on the strand, which gives grip and separation rather than a set film that cracks.

    • emollient
    • light ester
    • oil
    • wax
  • 12 Theobroma Cacao (Cocoa) Seed Butter
    General function

    A firm plant butter used for sealing and hold in heavier styling creams.

    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

    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
    • sealant
  • 13 Butyrospermum Parkii (Shea) Butter
    General function

    A rich, solid plant butter used for heavy conditioning on coarse or dry hair. High in the list it makes a product decidedly heavy.

    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

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

    • butter
    • emollient
    • sealant
  • 14 Hydrolyzed Wheat Protein/Pvp 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.

    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

    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.

    May suitVery dry or highly damaged hair

    Hydrolysed fragments are small enough to sit in the gaps of a worn cuticle for a wash or two, temporarily restoring stiffness and cutting breakage in combing.

    • film former
    • polymer
    • protein
    • hydrolysed protein
  • 15 Hydrolyzed Wheat Protein PG-Propyl Silanetriol
    General function

    A protein given a positive charge so it deposits where hair is damaged. It conditions and adds temporary firmness in one ingredient.

    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

    A cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.

    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.

    May suitVery dry or highly damaged hair

    General function

    A corn starch given a positive charge so it deposits on hair for slip and light body.

    Secondary ingredient

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

    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.

    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.

    May suitVery dry or highly damaged hair

    The class that does the detangling in a conditioner. It deposits lubrication where the cuticle is worn.

    • conditioning agent

    General function

    Wheat protein broken into amino acids, used for lightweight moisture binding.

    Secondary ingredient

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

    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
  • 18 Caprylyl Methicone
    General function

    A light silicone used for slip and to help other silicones spread.

    Secondary ingredient

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

    Lays a smooth film along the cuticle, which lowers combing friction and flattens the surface irregularities that read as frizz.

    May not suitBuild-up-sensitive routines

    Dimethicone does not disperse in water. On a routine that skips detergent it stays on the hair and accumulates wash after wash.

    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.

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. 5 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 $38 is the price we have observed for the 5 oz. We need three stores before we call a price commonly seen.
  3. Good value under $26 comes from the 5 products we score as doing the same job as this one. A quarter of them cost less than $5.10/oz; at 5 oz that is $26. Under that line you are paying less than most of them.
  4. About $29 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 5 oz.

This is a complete mouss formula. It is also above the range for mousses per ounce, with 2 close matches selling for meaningfully less.

How the score is counted
  • 2 products that do the same job cost less per ounce
  • Costs more per ounce than 94% of the 138 mousses we’ve priced
  • Covers 6 of the 6 things a mouss should do
  • Salon tier

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.

Does the same job, for less

Same derived functions — what it cleans, conditions, coats or holds — at a lower cost per ounce. Scent, texture and where you buy it can still differ.

Hair that craves moisture who want moisture that stays in and defined, clumped curls

Biggest tradeoff

Worth skipping for anyone sensitive to fragrance, curly-method routines, or very dry or very humid climates

We do not sell products or take placement fees. This page states what the formula and the prices show; the consultation is what matches it to a person.

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.

Creates bouncy curls with visible volume and lift without weighing hair down, which reviewers found especially beneficial for fine or thin hair textures.

Provides soft-hold curl definition without the crunchiness that many other mousses leave, and reviewers specifically praised the moisturizing feel of the formula.

Application amount matters significantly; using too much product causes the hair to feel crunchy and weighed down instead of soft and bouncy.

Controls frizz effectively while retaining moisture and hydration in curls, making it particularly appealing for managing humidity and environmental challenges.

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 (0 manufacturer or regulatory, 2 retailer, 0 editorial), last checked 2026-09-05.
  • Ingredient references are linked for 15 of 31 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 2026-09-05.
