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 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.

Humidity resistance Claimed

The brand claims humidity resistance; the ingredient list cannot confirm it.

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 Rinses with water

The silicones here are the water-soluble kind.

Fragrance Present

Fragrance is listed; it sits below the working ingredients.

Full ingredient list (26)

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/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 Hydrofluorocarbon 152a

General function
A non-flammable aerosol propellant used in dry shampoos and finishing sprays.

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

3 Isopentane

General function
A very fast-evaporating carrier used in aerosols to make the spray dry almost instantly.

Leading ingredient
Listed in the first three ingredients, it is likely a structural part of this formula.
PubChem
- solvent
4 VP/VA Copolymer

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

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.

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
5 Polyacrylamide

General function
A thickening polymer that also leaves a light film, used in gels and styling creams.

▾Below about this point, order stops being meaningful — these are typically used at 1% or less.
6 Iodopropynyl Butylcarbamate

General function
A preservative used at very low levels against mould and yeast.

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
7 C13-14 Isoparaffin

General function
A light carrier used to spread silicones and polymers thinly.

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.
- emollient
- solvent
8 Hydrolyzed Silk

General function
A light protein used for slip and shine rather than strength.

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
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
- protein
- hydrolysed protein
9 Laureth-7
- emulsifier
- solubilizer
10 Sodium Cocoyl Amino Acids

General function
An amino acid of the kind hair protein is built from. Small enough to sit inside the cuticle, and used for water binding rather than strength.

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
Amino acids are the smallest protein fraction and bind water as well, so they add far less stiffness than a hydrolysed protein does.

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.

DependsProtein-sensitive hair
The lightest option in the protein family, but still protein — worth watching if protein reliably stiffens your hair.

- mild anionic cleanser
- humectant
11 Potassium Dimethicone Peg-7 Panthenyl Phosphate
- emulsifier
- silicone
- water-soluble silicone
12 Peg/Ppg-18/18 Dimethicone

General function
An ethoxylated or propoxylated formulation aid. Ingredients of this family keep oils, silicones and fragrance evenly dispersed in a water-based 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.

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.
- emulsifier
- silicone
- water-soluble silicone
13 Diazolidinyl Urea
- formaldehyde releaser

14 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
15 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.

19 Fragrance · FRAGRANCE/PARFUM

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.

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

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.
Seen at $22.50 is the price we have observed for the 8 oz. We need three stores before we call a price commonly seen.
Good value under $9 comes from the 7 products we score as doing the same job as this one. A quarter of them cost less than $1.19/oz; at 8 oz that is $9. Under that line you are paying less than most of them.
About $23 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 8 oz.

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.

Reviewers

What people report

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

One fine, flat-haired user says it adds lots of volume without weighing the hair down.

fine flat hair

A critical reviewer reports dry, frizzy hair after a month of use and says the product dispenses as a clear spray rather than a foam.

short-hair user applying to damp hair

A flat, thin-haired reviewer says the spray-foam gives a noticeable root-volume boost without a sticky or crispy feel, though the volume fades sooner than desired.

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.
3 sources consulted for this product (1 manufacturer or regulatory, 2 retailer, 0 editorial), last checked 2026-08-26.
Ingredient references are linked for 6 of 15 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.
