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 Unlikely

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

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 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 (37)

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

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.

4 Hydrolyzed Soy Protein

General function
A plant protein used for body and moisture retention.

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

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.

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
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.

10 Prunus Insititia Seed Oil

General function
The oil pressed from Prunus Insititia. 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.

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.

12 Panthenol

General function
Provitamin B5. It draws in water and penetrates the strand a little, which is why it is the standard ingredient for softness and shine claims.

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
It hydrates without adding oil or a film, which is the combination fine hair usually needs.

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.

May suitVery dry or highly damaged hair
A humectant that also penetrates the cuticle, so it holds water inside the strand rather than only on the surface.

PubChem
- humectant
- conditioning agent
- vitamin
13 PVP

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

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 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.

DependsCurls or waves needing flexible hold
It sets firm on its own. Whether the curl stays flexible depends on the plasticisers and oils the rest of the formula carries.

PubChem
- film former

14 Polyquaternium-4

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

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 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.

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
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.

21 Sodium C14-16 Olefin Sulfonate

General function
A strong non-sulfate detergent used in "sulfate-free" shampoos. It cleans about as thoroughly as a sulfate despite the label difference.

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.

General function
A conditioning agent closely related to cetrimonium chloride, used for static control and easier combing.

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
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.

DependsBuild-up-sensitive routines
Substantive by design. A routine with no detergent wash gives it nothing to leave with.
- conditioning agent
24 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
25 Silicone Quaternium-3

General function
A positively charged silicone that deposits where hair is damaged, for smoothing that survives rinsing.

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 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

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
28 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

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.

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

6.5 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.
Seen at $31 is the price we have observed for the 6.5 oz. We need three stores before we call a price commonly seen.
Good value under $9 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $1.42/oz; at 6.5 oz that is $9. Under that line you are paying less than most of them.
About $13 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 6.5 oz.

Formula

Formula score

9 of 10

The formula carries what a mouss is built around, and 3 products we score as close matches cost at least a quarter less per ounce. The difference is buying the label, not a different formula.

Should you buy it?

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.
1 source consulted for this product (0 manufacturer or regulatory, 1 retailer, 0 editorial), last checked 2026-08-27.
Ingredient references are linked for 15 of 23 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.
