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)
Light
A light hold, as stated by the brand.
Hold system
Mixed
Gums and synthetic polymers together.
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.
Oils and butters
None
No oils or butters in the list.

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.

Propane
General function
An aerosol propellant, usually blended with butane to set the spray pressure.
Supporting ingredientPubChemListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

Hydrolyzed Rice Protein
General function
A light plant protein that adds body and shine, popular in volume products.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitFrizz-prone, damaged, or high-friction hairFilling 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 stylingFilm 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 hairHydrolysed 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.

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.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
PubChemMay suitFine or easily flattened hairIt hydrates without adding oil or a film, which is the combination fine hair usually needs.
May suitFrizz-prone, damaged, or high-friction hairDeposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.

Estimated lower-concentration zoneIt 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 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 suitCurls or waves needing flexible holdThe detergent class most curl routines are built around: it lathers and cleanses without stripping the strand back to bare.
May suitDry, coarse, or high-porosity hairA gentler detergent leaves more of the surface oil that slows water loss from coarse or porous hair.
May suitVery dry or highly damaged hairCleanses with less sebum removal than a sulfate detergent, so hair that is short of moisture keeps more of it through the wash.

Dehydroxanthan Gum
General function
A plant or fermented gum. Gums thicken a water-based formula and give it a slippery, cushioned feel; in a styler they also contribute soft hold.
Estimated lower-concentration zoneIt 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 holdA polysaccharide film stays softer than a synthetic one as it dries, which is what leaves a curl defined but still able to move.
May suitFrizz-prone, damaged, or high-friction hairA soft film binds neighbouring strands together, which is most of what helps flyaways lie down.

Estimated lower-concentration zoneIt appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
International Journal of Cosmetic ScienceMay suitFine or easily flattened hairThe C16 quat binds mostly by charge rather than by chain, so it deposits measurably less than the C22 ones. Less deposit is less conditioning and also less weight, which is usually the trade fine hair wants.
May suitFrizz-prone, damaged, or high-friction hairA cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.

PubChemMay suitVery dry or highly damaged hairHumectants bind water into the strand, and water — not oil — is what makes dry hair flexible instead of brittle.

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
- 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.
- Commonly seen is the middle half of current prices for the 7 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 $9 comes from the 7 products we score as doing the same job as this one. A quarter of them cost less than $1.34/oz; at 7 oz that is $9. Under that line you are paying less than most of them.
- About $18 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 7 oz.

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.
- 2 sources consulted for this product (1 manufacturer or regulatory, 1 retailer, 0 editorial), last checked 2026-08-27.
- Ingredient references are linked for 9 of 18 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 2026-09-04.
