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 kind of hold.
Cast risk
Likely
Film formers with little to soften them, so 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.

Full ingredient list (29)
In the US, ingredients above 1% are listed from most to least. Below 1% they can appear in any order. Each note keeps three things apart: what the ingredient generally does, its role in this type of product, and what its position can tell you.

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

Hydrofluorocarbon 152a
General function
A non-flammable aerosol propellant used in dry shampoos and finishing sprays.
Leading ingredientPubChemListed in the first three ingredients, it is likely a structural part of this formula.

VP/VA Copolymer
General function
A hold polymer that dries to a clear film. It sets the style and washes out with water.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
May suitClimate-sensitive or frizz-prone hairA set polymer film is a physical barrier to humidity, so a style keeps its shape longer in damp conditions.
May suitMaximum-hold stylingSynthetic film formers dry into a continuous film, which is what holds a shape against movement and against humid air.
DependsBuild-up-sensitive routinesSome acrylate copolymers rinse with water and some need a detergent; the label alone does not say which one a formula used.
- film former
- polymer

4
Dimethyl Ether
General function
An aerosol propellant that also helps the formula spray as a fine, fast-drying mist.
Supporting ingredientPubChemListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
- propellant
- solvent
-
5
Isopentane
General function
A very fast-evaporating carrier used in aerosols to make the spray dry almost instantly.
Supporting ingredientPubChemListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
- solvent
-
6
PVP
General function
A classic hairspray polymer. It gives firm hold but attracts moisture, so humidity can soften the set.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
PubChemMay suitMaximum-hold stylingSynthetic film formers dry into a continuous film, which is what holds a shape against movement and against humid air.
DependsBuild-up-sensitive routinesSome 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 hairThe 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.

PEG-12 Dimethicone
General function
A water-soluble silicone that smooths without the build-up concern of standard silicones.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitBuild-up-sensitive routinesThe 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 hairA 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 hairDelivers the slip and surface smoothing of a silicone without needing a detergent wash to remove it afterwards.

May suitVery dry or highly damaged hairOne of the mildest detergent classes. It is usually there to let a formula lather without a harsher detergent doing the work.

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
- 10 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.
- Commonly seen is the middle half of current prices for the 10 oz at recognised stores. We leave out the cheapest and most expensive quarters, so one sale or one overpriced listing can’t move it.
- Good value under $18 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $1.80/oz; at 10 oz that is $18. Under that line you are paying less than most of them.
- About $27 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 10 oz.

The formula score measures completeness for the job: a weighted share of the systems this product type is usually built around that we find in this list. It does not rate how well the product works or its quality, and it never compares across product types.

Claims check
What the brand says, and what the formula shows
Claims are quoted from the brand. We mark a claim supported, partly supported or conflicting only when the ingredient list speaks to it. Everything else stays "stated by the brand". That isn’t a criticism: most claims can’t be checked from a label.

How this page was made
- Everything above comes from our researched product record: identity, the ingredient list as printed, the brand's own claims, dated prices and review themes our researchers wrote in their own words. No part of this page is written by hand for one 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 12 of 19 product-aware annotations on this page. Fit notes are general formulation guidance. They aren’t a verdict on the finished product or on you.
- We haven’t tested this product in a lab, and we don’t physically test your hair. Formula readings come from the ingredient list. Claims about how it behaves are labelled as the brand's.
- Ingredient order tells you relative amount only above roughly 1%. Prices are what we saw on the dates shown and can change.
- 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 v23. Record last updated 2026-08-27.
